The abstruseness begins with a man abounding advised a archetypal citizen. To his son, Jon, and daughter, Jocelyn, Dr. David Cornbleet was both a ancestor and a friend.

And he volunteered to advice strangers as well. He advised bake victims in New York afterwards 9/11 and patients in Louisiana afterwards Hurricane Katrina.

JON CORNBLEET: He aloof admired to give. He admired life, actual blessed person, blithe guy.

But he additionally actual anticipated aback it came to time.

His son says he formed beeline admitting the day afore calling home amid 6 and 6:30 p.m., and afresh alive aback to the abode for a home-cooked meal with his wife Aileen. They were affiliated 38 years.

JON CORNBLEET: My dad is the best authentic actuality in the world. I mean, he does aggregate basically at the aforementioned time. And I knew at that point there was article amiss with why he didn't call.

So Jon alleged Jocelyn to analysis on their dad because she lived abutting to his burghal office. She accustomed aural 20 minutes, her fiance not far behind. She begin the aperture to his 12th attic arrangement unlocked,and bound absolved accomplished his three analytical rooms.

JOCELYN CORNBLEET: The aboriginal two rooms, the doors were closed. The aftermost one was open, so I went beeline aback into the aftermost allowance and there was annihilation in there. And I angry around, and as I was axis around, on the aperture to the additional room, which was closed, there was claret beyond it. So I knew that he was in there and opened the aperture and saw him on the floor.

He was dead. Her ancestor was dead. She anon alleged 911.

JOCELYN CORNBLEET: I said, "I allegation an ambulance here. My father's been murdered."

Then she phoned her mother.

She additionally alleged her fiance, Dan Drucker, who accustomed moments afore the badge and chock-full at the aboriginal attic aegis desk.

DAN DRUCKER: I asked the aegis bouncer who was sitting there, "What attic is Dr. Cornbleet on?" And she goes, "The 12th floor." And I go, "I anticipate he's aloof been murdered." And it was the acknowledgment she gave was actual affectionate of shocking. She was like. "Oh, my God - I can't accept it." Not so abundant like a shock of, like “What are you saying?” But added of like “That explains it,” 'cause it seemed like she knew article from before.

ROB STAFFORD: It seemed like she had apparent something?

DAN DRUCKER: Yeah, she had apparent something.

Turns out she had apparent article - a man acting strange, with claret on him. Luckily, so had the building’s aegis cameras. Soon, the badge would accept this tape, which aloof ability acquaint the accomplished story: Who was this man? And did he annihilation a admired doctor?

Dan Drucker accustomed at Dr. Cornbleet's arrangement aloof account afterwards his fiancee had begin her ancestor - murdered.

DAN DRUCKER: She was just a complete wreck, crying. [She] credibility me in the administration area in the arrangement area he is. I aloof advance accessible the slightly. I see him laying there. That was abundant advice for me. My capital job afresh was aloof to animate her.

Later, the sad job of anecdotic Dr. Cornbleet fell to his son, Jon.

JON CORNBLEET: They said that he was so burst and so baffled up that they aloof showed me, actually, a account of his head. My father, alike at 64, had a appealing abounding arch of beard and his beard had been shaved. So it was actual adamantine to attending at. I still see that angel all the time.

At the funeral, Jon was the aftermost to leave and the aboriginal to adjudge his ancestors would comedy an alive role in the investigation.

JON CORNBLEET: I looked bottomward in his grave and I was arrant . And I fabricated a vow to him appropriate afresh and there. And I said, "I'm not gonna arise aback until I acquisition amends for you."

The Cornbleets were grieving, but they were bent to acquisition their father's killer, and to do that they would accept to apprentice everything, no amount how difficult, about what happened before, during and afterwards the murder.

ROB STAFFORD: What do badge anticipate happened central your father's office?

JON CORNBLEET: Well, they apperceive that there's a huge attempt aloof basically because a lot of things in the arrangement were agape around. There were a lot of burst chairs and whatnot.

ROB STAFFORD: Your ancestor fought back?

JON CORNBLEET: My ancestor fought back. My ancestor was 64 years old, but he was in abundant shape. He was in absolutely acceptable concrete condition.

But in the end, the antagonist was able to overpower and ache him to death. Added than 20 wounds were begin on his body. It was a abandoned attack, but why? His arrangement wasn't ransacked; annihilation was stolen, not alike cash.

ROB STAFFORD: Did your ancestor accept enemies?

JON CORNBLEET: No, he didn't accept any enemies.

ROB STAFFORD: Could you anticipate of anyone who would accept done this?

JON CORNBLEET: No.

ROB STAFFORD: And did you go through every name you could possibly anticipate of?

JOCELYN CORNBLEET: There wasn't anyone to go through. He wasn't a adumbral character. He didn't do drugs. He wasn't accepting affairs. He wasn't that affectionate of person. There was not one actuality we could anticipate of who could do that. I beggarly we affected it would be a accommodating because that would be the abandoned actuality that could accomplish sense. But he didn't accept complaints. There wasn't bodies that were suing him. So we didn't accept anybody to point a feel at.

But badge had a lot of clues to assignment with: Concrete affirmation larboard at the amphitheatre and cine from the architecture aegis cameras, which showed a adolescent man walking in and out - a man the aegis bouncer had seen.

ROB STAFFORD: What do you see on the tape?

JON CORNBLEET: I aloof saw a adolescent man aggravating to burrow his identity, walking into the architecture actual suspicious-looking aloof in how he was bath abroad from the cameras. And afresh aback you see him leaving, it's actual axiomatic that, you know, article had occurred.

ROB STAFFORD: Are you assertive that man on the band is the man who asleep your father?

JON CORNBLEET: Yeah - we were assertive of it appropriate away.

ROB STAFFORD: Appropriate away?

JON CORNBLEET: Appropriate away, yeah. Somebody absolutely rode bottomward the elevator with the adolescent man and she declared him as actuality actual suspicious. He was breath actual heavily, aggravating to awning up his face, had claret on his shoes, which she anticipation was actual peculiar. Claret was advancing out of his nose.

The man on the band appeared to apperceive absolutely what he was doing, anxiously concealing his face from the camera.

JOCELYN CORNBLEET: He wears altered hats as well.

ROB STAFFORD: He goes in cutting one hat and comes out cutting a altered one?

JOCELYN CORNBLEET: Right. He additionally uses some affectionate of tissue or handkerchief aback he pushes accessible the aperture and aback he touches the elevator button to advance it - so as not to leave fingerprints so it absolutely fabricated him added suspicious.

JON CORNBLEET: This was a carefully-plotted murder, that this was somebody who went in there with the ambition to annihilate him.

ROB STAFFORD: You anticipate your ancestor was targeted.

JON CORNBLEET: Definitely.

ROB STAFFORD: How generally do you anticipate about what allegation accept happened?

JON CORNBLEET: I anticipate about it everyday. What went bottomward there and what the attempt was like. What affectionate of affliction he was in, what his aftermost thoughts were 'cause it's got to be bizarre. You know, there you are in your own arrangement accessible to advice bodies and this bedlamite comes in there with a knife aggravating to aching you.

The analgesic larboard abaft DNA and an abnormal but bare accouterments abundance item. The badge won't acquaint us what it is, but that item, forth with its packaging, seemed to be advantageous affirmation for detectives to assignment with.

DAN DRUCKER: They came in appealing assured that they anticipation would bolt the actuality - that it was somewhat of a awkward crime, if you will.

And afresh they had that surveillance band - so they knew the man they were attractive for was young, white, albino and about 6 anxiety tall.

ROB STAFFORD: Do you anticipate that badge will break this quickly?

JON CORNBLEET: I anticipation it was gonna be actual quick.

Image Source:

But two months later, there was no arrest, not alike a suspect. Afresh there was a accessible break: It turns out that abnormal accouterments account the analgesic larboard abaft was awash abandoned at Home Depot stores. Badge were reviewing abundance aegis tapes aback they spotted a man who seemed to attending familiar, affairs that abnormal account three and a bisected weeks afore the murder.

JON CORNBLEET: This actuality was the abandoned one who akin the description and this actuality abandoned bought this authentic item, which is affectionate of a appropriate item. That's what prompted badge to say, “The detectives absolutely wanna allocution to this person.”

The badge arise the video to the media with a appeal to the accessible to advice acquisition the man.

ROB STAFFORD: You're assertive the guy on the band at Home Depot was the man that asleep your dad.

JON CORNBLEET: Yeah, I was assertive of it.

Two pieces of band of a man the Cornbleet ancestors and the badge anticipation were one and the same. But alike with the absolution to the accessible of both tapes, the abomination remained unsolved. A new analytic apparatus was bare -- so the ancestors angry to MySpace.

Images from surveillance tapes at a high-rise architecture and at a Home Depot abundance were the best affirmation so far in the chase for the man who'd atrociously stabbed Dr. Cornbleet to afterlife in his own office. But weeks into the investigation, Chicago badge still had no abstraction who the analgesic was.

ROB STAFFORD: What are badge cogent you about the investigation?

JON CORNBLEET: That it's actual slow, it's actual complicated, actual complex. And, you know, actuality we accept a abundance of argumentative evidence, we accept witnesses, we accept surveillance tapes. Yet, we can't amount out who this actuality is.

ROB STAFFORD: Are you accepting frustrated?

JON CORNBLEET: I'm accepting actual balked by it.

JOCELYN CORNBLEET: I anticipate the badge were as well. It wasn't your archetypal crime.

And Jon, Jocelyn and her fiance, Dan Drucker, began to accept the abomination would not be apparent in a archetypal way... So they asked themselves, area would you attending for a 20-something suspect? And that's aback Dan, who works in marketing, came up with an idea.

JON CORNBLEET: Dan says to me, "I anticipate we allegation to use accoutrement that the aggressor and his accompany would be on - those actuality MySpace, YouTube, things like that. The archetypal 20 to 25-year-old absolutely isn't gonna be watching the account or account the acceptable media newspapers.

ROB STAFFORD: So you adjudge to ambition the associate accumulation of the killer.

DAN DRUCKER: Basically the action was that I anticipate everybody anticipation the best advice was activity to arise from his peers. So at that point I told Jon that we accept to get online. I capital to put it aural an amphitheatre area by the nature, bodies are analytic for, abutting with and aloof overextension advice - and MySpace absolutely was the best way to do it.

They acquaint a flyer on MySpace forth with the badge buzz cardinal and they paid to accept the surviellance band from the arrangement and Home Depot enhanced, which they uploaded assimilate the Web.

DAN DRUCKER: Aloof by the attributes of the site, you're - you're able to affix with people, allure them to be your accompany and if they end up actuality your friends, they're absolutely affiliated to your site. So you can acquaint with them in assorted ways. But alike if they adjudge not to be your friend, they'll still be apparent to your site. So it's about like handing a flyer to someone.

Right abroad the acknowledgment was overwhelming.

DAN DRUCKER: Once Jon and I were on the armpit agreeable friends, we would be accepting 30 to 40 acquaintance requests every distinct day. And they would accelerate it off to their friends, all throughout the nation. It was phenomenal, the acknowledgment we got.

At first, best of the responses were condolences from bodies who knew him, like this one:

“I visited your ancestor already about 6 or 7 years ago to get some warts removed from my arm. He was a actual affectionate and affable man and I can't delay until this fiend is caught.”

“I ambition I could analyze this man. Pray that u acquisition him soon.”

There were additionally account and suggestions offered about aggravating to analyze the hats he was wearing, analytic whether he could be a bagman or messenger, admiration the analgesic was a academy apprentice active abreast the Home Depot the band came from.

All were accepted by the Cornbleets, but none led anywhere.

ROB STAFFORD: How did the badge acknowledge to what you were doing?

JON CORNBLEET: Annihilation to advice the case, they were pro. And they thought, "Hey, this is absolutely different," article they had never dealt with before, but they were appealing acceptant to it.

Jon additionally put up flyers about the city, abnormally abreast the Home Depot area the bearding man bought that appropriate account like the one larboard at the abomination scene. As time passed, Jon became alike added assertive this was the man who murdered his father.

JON CORNBLEET: 'Cause, I thought, “If it was me and I accustomed myself and I apperceive what food I purchased what at, I would accept austere my name immediately.” And aback that didn't arise aural a month, afresh I anticipation to myself, "This has to be the appropriate person."

ROB STAFFORD: You put the account out.

JON CORNBLEET: We did.

ROB STAFFORD: And you're accusation hard.

JON CORNBLEET: We're accusation --

ROB STAFFORD: -- to get answers.

JON CORNBLEET: Correct.

ROB STAFFORD: You wanna acquisition the guy on that tape.

JON CORNBLEET: Correct.

Then, finally, the man on the Home Depot band came forward.

JON CORNBLEET: He alleged the badge and said, "I'm the guy and I don't alike apperceive who this doctor is. - I allegation to about-face myself in over this. We allegation to ablaze this."

It turns out this adolescent man had a acumen for authoritative the acquirement and a assured account for the time of the killing.

ROB STAFFORD: Did the man on the Home Depot band accept annihilation to do with your father's death?

JON CORNBLEET: No, absolutely not.

After all that, the Home Depot advance was a asleep end. It was a big disappointment, but the family's MySpace Website was about to pay off. About the aforementioned time, their folio had accustomed a abstruse e-mail in the wee hours of April 12, six months afterwards the annihilation of dr. David Cornbleet.

JON CORNBLEET: The accountable was, "Jonathan, do not delete." And acutely I apprehend it and aloof by the accent of the email and what he wrote in there and how aboveboard this actuality sounded, I knew that this was a appealing authentic advance appropriate away.

In fact, it'd be the advance they'd been cat-and-mouse for -- and it was a shocker.

Six months afterwards vowing to acquisition his father's killer, Jon Cornbleet woke up to acquisition an email he was apprenticed not to delete. A man in New York had article he bare to say.

JON CORNBLEET: It basically says that "I'm a Abyssal and I don't wanna get your hopes up, but I accept that I accept advice pertaining to this case." And afresh he attempted to lay out area he was from, area he went to college, what infantry he was with, so it looked very, actual aboveboard and actual compelling.

The Abyssal had additionally contacted the Chicago police.

JON CORNBLEET: A Abyssal isn't gonna alarm the badge and accord them affected information.

But what would a U.S. Abyssal aloof home on leave from Iraq - apperceive about the annihilation of a doctor in Chicago a bisected year earlier? Jon capital to allege with him and asked the Abyssal to alarm him.

JON CORNBLEET: My buzz rings at about 12:00 that afternoon. I aloof knew by the accent of his voice, by how abundant advice that he had, I knew that this was very, actual accurate.

In this email to Dateline, the Marine, who wants to abide anonymous, describes seeing a acquaintance who was scared, afraid and not himself. Aback the Abyssal asked him what was wrong, he artlessly said: "I anticipate my above acquaintance asleep someone."

According to the Marine, his acquaintance said the man had been one of his attached for best of 2006 in an accommodation in New York City's high east side. The acquaintance declared the acquaintance as "increasingly anti social, manic, decumbent to bourgeois behavior, generally blockage alive for days"... And he threatened to abuse a doctor who said he had done him wrong.

Then in October 2006, the acquaintance abruptly larboard New York for several days, afresh returned, arranged a attache and larboard again. About two weeks later, the Marine's acquaintance heard about Dr. Cornbleet's murder, "put two and two together" and had what he alleged "a gut activity that article angry had gone down."

Most important, though, the acquaintance had the name of the man he anticipation was the killer.

JON CORNBLEET: The name is Hans Peterson.

ROB STAFFORD: Had you anytime heard that name before?

JON CORNBLEET: No, I had never heard that name before.

ROB STAFFORD: Jocelyn?

JOCELYN CORNBLEET: No, never.

ROB STAFFORD: Dan?

DAN DRUCKER: No.

But Chicago badge were able to bout the name anon to the account of Dr. Cornbleet's patients. Hans Peterson had apparent the doctor bristles years earlier. The catechism was, did Peterson's DNA bout the DNA at the annihilation scene? Peterson no best lived in New York, in fact, the Abyssal said he no best lived in the country, but the abyssal knew the abode of his above apartment. So detectives flew to New York, they went to the accommodation attractive for DNA, and they begin it on a cigarette butt.

ROB STAFFORD: Did the DNA match?

JON CORNBLEET: It was a match.

Peterson was no best in New York, but the ex-roommate did accept a forwarding abode for Peterson, which the Abyssal gave to police: It was in the Caribbean island of St. Martin in the French West Indies.

Image Source:

JON CORNBLEET: He knows every distinct aspect about area this actuality is appropriate now.

ROB STAFFORD: You anticipate this case is solved.

JON CORNBLEET: Essentially, yes.

So did the police. Armed with evidence, including the surveillance video and a DNA match, they issued an all-embracing arrest warrant. But there were still two big questions in the case. One: would the connected arm of the law be able to grab him in the Caribbean?

JOCELYN CORNBLEET: We aloof affected that our government - the FBI would allege to the admiral in St. Martin, explain the situation, appearance the evidence. They would arise in and arrest him and accelerate him aback to the United States because the affirmation was aloof so overwhelming. This is what my brother and Dan had been alive for - for months to achieve. And we were gonna access amends for my dad.

The additional question: could there be any affectionate of aegis for such a aboriginal murder? An accepted acknowledgment to that catechism would arise from the suspect's own father.

ROB STAFFORD: You assume to be blaming the victim.

THOMAS PETERSON, Hans Peterson’s father: Who are you calling the victim?

Hans Peterson had fled the country to the island of St. Martin in the French West Indies. Aback in his home accompaniment of Oregon, his father, addition doctor alleged Thomas Peterson, watched the high-rise surveillance band for the aboriginal time.

ROB STAFFORD: You attending at that aegis camera video and what do you see?

THOMAS PETERSON: I see that is him walking in and out of there - yeah.

ROB STAFFORD: Your son?

THOMAS PETERSON: Yes.

ROB STAFFORD: Did your son annihilate Dr. Cornbleet?

THOMAS PETERSON, Hans Peterson’s father: I accept so.

Dr. Cornbleet lived his activity by the active of a clock. And Hans Peterson, too, seemed to accept a alarm active in his life, nut in his case it may accept been counting bottomward to disaster.

The ancestor says Hans, who played football as a boy, was already abounding of promise. He describes him as acutely ablaze as a adolescent but socially awkward.

THOMAS PETERSON: There was a lot activity on in his head, but he didn't consistently enunciate it much. But everyone admired him.

His son's backwardness became a botheration as he got older.

THOMAS PETERSON: He would actual rarely admit a conversation. He wouldn't generally allege added than a few sentences at a time.

ROB STAFFORD: Were you afraid about it?

THOMAS PETERSON: It aloof was who he was. About age 15 or 16, you know, aback amusing activity became added important and he became a bit depressed, you know, we took him to the doctor, he got on anti-depressants, and his abasement seemed to be somewhat cyclical. It would affectionate of arise and go.

ROB STAFFORD: Did the medication help?

THOMAS PETERSON: It seemed to help. It seems to bland out the bumps in the ride. I don't anticipate it really, you know, makes the botheration go away.

ROB STAFFORD: Allegation accept been difficult for you as a dad to see him struggle.

THOMAS PETERSON: Yeah, it's consistently adamantine to see your accouchement struggle.

After acceptance from the University of Wisconsin with a bifold above in economics and philosophy, Hans eventually took a job as an options banker in Chicago in 2002. Anxious about an abscess problem, that bounce he best Dr. Cornbleet out of a buzz book and fabricated an arrangement -- an arrangement that would change abounding lives.

ROB STAFFORD: May 2002, what happens?

THOMAS PETERSON: I get a alarm from him saying, "I took this abscess biologic and I am activity horrible. I'm actual depressed, I can't anticipate straight. I accept a abhorrent headache, I accept this abhorrent babble in my ears. I allegation to arise home."

ROB STAFFORD: What did you say?

THOMAS PETERSON: “I'll get you a acceptance to arise home tomorrow, backpack your actuality up and stick it about and we'll anguish about it later.”

Hans told his ancestor the account of his affecting abatement was Accutane, the biologic Dr. Cornbleet had assigned him. It comes in assorted doses, but Hans told his ancestor he was assigned the accomplished one - two 40 milligram pills - that he took for two days. Hans says Dr. Cornbleet told him to booty both pills at the aforementioned time rather than abandoned during the day as recommended.

THOMAS PETERSON: He alleged Dr. Cornbleet aback he started accepting the headaches and Dr. Cornbleet told him to stop the medication.

ROB STAFFORD: Did your son go aback to see Dr. Cornbleet?

THOMAS PETERSON: I don't accept so.

Hans flew home to his father, who says he was abashed by the son he saw.

THOMAS PETERSON: He's actual agitated. There was a attending of affliction in his eyes, but yet his eyes were vacant, you absolutely couldn't acquaintance him. And he was captivation his arch in pain.

ROB STAFFORD: Had you anytime apparent him like this before?

THOMAS PETERSON: Never. This was annihilation like his depression. He was in pain. You couldn't attending in his eyes and accept a animal to animal chat about anything.

ROB STAFFORD: And what does that feel like for you?

THOMAS PETERSON: It feels like I absent my son.

ROB STAFFORD: Did you alarm Dr. Cornbleet?

THOMAS PETERSON: No.

He took Hans to assorted doctors for advice and says a analyst diagnosed Hans as certifiable and assigned Zoloft, an anti-depressant.

Still, admitting his problems, Hans took the law academy acceptance analysis and did so well, he accustomed a scholarship to a law academy in New York, area he enrolled in January 2003.

ROB STAFFORD: Does he abide to booty anti-depressants?

THOMAS PETERSON: Yes.

ROB STAFFORD: How does he get them?

THOMAS PETERSON: He would get them off the Internet at times. And at times, I would get a atrocious buzz alarm from him saying, "I'm out of Zoloft, can you alarm in a prescription?" I would acquaint him, "You allegation to accept a analyst there at the academy demography affliction of you. I will get you abundant for two weeks."

ROB STAFFORD: Did your son see a psychiatrist?

THOMAS PETERSON: I don't accept he did.

As graduation approached in the bounce of 2005, Hans chock-full abiding his father's buzz calls.

THOMAS PETERSON: So I larboard him a bulletin saying, "I'm gonna alarm the badge for a missing person." So he calls and afresh tells me that he had not been activity to classes and had clearly taken a leave of absence a ages ago. And he is now become an online gambler. Aback his abasement is beneath control, he's accomplishing actual well, and aback his abasement is bad, he's not playing.

For addition year, his ancestor says Hans connected to alive in New York City, bank online as his job, and rarely socializing... still bedeviled with Accutane and the doctor who assigned it.

Then, in October 2006, according to Jon Cornbleet, Hans busy a car in New York and collection 800 afar to Chicago. Using a apocryphal name, he alleged and fabricated an arrangement with Dr. Cornbleet for 4:45 p.m. - the aftermost arrangement of the day - on Tuesday, October 24.

Jon told us what he understands happened next. Hans Peterson went to Chicago to advise the doctor a assignment and took with him a apparatus bag for torture: accustomed a rope, aqueduct tape, pliers, a hacksaw, knife, alike a baby draft torch. His plan was to cut off the doctor's easily and anxiety and use the draft bake to bake his limbs. But the plan went amiss aback the doctor fought back, so Hans stabbed him to death.

Two months later, in backward December 2006, Hans confused to St. Martin, area he lived abandoned in this admiral apartment, afterwards adopting suspicion - until aboriginal August 2007, aback he begin out the FBI was closing in. Afresh he abruptly absolved into a badge base and accepted to French authorities that he murdered Dr. Cornbleet. He was taken into custody.

Even alive all that, Hans's ancestor believes his son is not alone amenable for the barbarous killing.

ROB STAFFORD: Who do you accusation for Dr. Cornbleet's homicide?

THOMAS PETERSON: It's a aggregate of factors. I would accusation Roche Pharmaceuticals for accepting this biologic on the bazaar in animosity of all the abominable things that accept happened. I would accusation the FDA for acceptance them to accumulate it on the market. I would accusation Dr. Cornbleet for giving it to him.

He says his son's abscess was not bad abundant to be accustomed such a able drug, with warnings of accessible austere ancillary effects, psychiatric ones. Because of these accessible ancillary furnishings and others, the biologic is controversial, its admonishing admit says doctors should appoint Accutane for abandoned the best astringent cases of acne. But because it's so effective, dermatologists frequently appoint it for all kinds of acne.

So is Accutane dangerous?

DR. DOUGLAS BREMNER, PSYCHIATRIST: I'm actual anxious about this drug.

Hans' ancestor referred us to this man, Dr. Douglas Bremner, a articulate analyzer of the drug, who is a analyst and radiologist at Emery University in Atlanta.

BREMNER: There's a cardinal of cases in the abstract of suicide and behavioral changes. Not a anniversary goes by that I don't apprehend of addition case arise to me, aloof from accompany and family.

Dr. Bremner conducted a abstraction on accutane that claims the biologic may affect a allotment of the academician complex with abasement - and can be actual chancy for some patients.

Image Source:

DR. BREMNER: I anticipate that it has furnishings on the academician that can advance to psychiatric ancillary furnishings like depression, suicidality, changes in behavior, including abandon and aggression.

Dr. Bremner has never met or evaluated Hans Peterson, but he thinks Accutane could accept contributed to Hans killing Dr. Cornbleet.

ROB STAFFORD: Is this a acceptable case of account and effect?

BREMNER: I don't anticipate that you can absolutely say that that was the sole account of this homicide.

ROB STAFFORD: Can you alike say for abiding that Accutane, the drug, had annihilation to do with this homicide?

BREMNER: I anticipate it did accord in some way because it acquired the psychiatric ancillary effects.

But his assignment on Accutane has its critics. His abstraction was actual baby and adjourned by bodies suing Roche over the drug. And admitting Dr. Bremner is an able attestant in some Accutane cases adjoin Roche, one adjudicator afresh barred his testimony, analytic whether he was accouterment "personal assessment or accurate science."

Roche, the maker of Accutane, expresses its accord for the Cornbleet family, but adds this case is about murder, not the drug. Accutane, it says, has been acclimated by millions of bodies common and is safe and effective. Although the amalgamation does backpack warnings about psychiatric contest and violence, the aggregation says abundant studies accept begin no account and aftereffect accord amid Accutane and those events, attenuate letters of violence, or animal dysfunction.

ROB STAFFORD: You're blaming this annihilation on a biologic your son took four and a bisected years afore this advance alike happened, and he abandoned took the biologic for two days.

THOMAS PETERSON: Right, 'cause it damaged his affecting brain.

ROB STAFFORD: You assume to be blaming the victim.

THOMAS PETERSON: Who are you calling the victim?

ROB STAFFORD: Dr. Cornbleet.

THOMAS PETERSON: Don't you anticipate Hans is a victim? There's two victims actuality and anniversary family's gonna alarm their own the primary aloof because that's what bodies do with families.

ROB STAFFORD: Dr. Cornbleet is dead.

THOMAS PETERSON: Hans is about never gonna be a activity affiliate of association again. There are assorted victims and assorted villains. And I feel that one of the victims is Dr. Cornbleet and one of the villains is Dr. Cornbleet. One of the victims is Hans Peterson; one of the villains is Hans Peterson.

Hans's ancestor says his son batten with attorneys about filing a abuse accusation adjoin Dr. Cornbleet, but no one capital to booty the case. Besides, he echoes what his son wrote online in July 2007.

THOMAS PETERSON: So what? So you book a lawsuit. Apprehend his blog. It says, "Their lives will go on with aloof a little beneath money. Our lives will never be the same." And you know, I anticipate there's a lot of accuracy in that.

Hans' ancestor says his son went addition way and exacted his own justice.

THOMAS PETERSON: It was his way to avenge what happened to him. His activity was destroyed by Accutane and Dr. Cornbleet was the abettor who supplied it. So this was vigilante justice, in his mind.

If Hans took the law into his own hands, the catechism would anon become: would the law get its easily on Hans?

JOCELYN CORNBLEET: I don't anticipate anyone could accept predicted what would arise next.

Hans Peterson says he stabbed Dr. David Cornbleet to death, and his ancestor blames it on a biologic and the doctor who assigned it.

Dr. Cornbleet's ancestors is affronted and angered by that notion.

JOCELYN CORNBLEET: To aspersion him and say that he, with intent, approved to do article abhorrent to his son makes me sick.

JON CORNBLEET: To me, aggregate with the Accutane is a lot of smoke and mirrors. If there were any actuality to this, he would accept filed a able accusation or complained a brace years back.

Dr. Bennett Leventhal is a analyst at the University of Illinois in Chicago and an able in psychopharmacology, the abstraction of drug-induced changes in mood, cerebration and behavior. He says cerebral problems associated with Accutane are anecdotal and not scientifically proven. Like Dr. Bremner, he additionally has never met Hans Peterson, but he says Hans appears to accept had austere problems afore he anytime took Accutane.

ROB STAFFORD: Do you anticipate Accutane aggravated the problems Hans already had?

DR. BENNETT LEVENTHAL, PSYCHIATRIST: I anticipate it's absolutely accessible that in the canicule afterwards he took Accutane for the aboriginal time and abandoned time, that he may had had an affliction of his symptons. But afterwards three, four, five, six days, Accutane was gone, and I anticipate apparently played little role in what transpired in the consecutive four or bristles years.

He additionally says while Hans may be mentally ill, accutane best acceptable had annihilation to do with that -- or the annihilation of Dr. Cornbleet.

ROB STAFFORD: Hans' ancestor said he saw a night and day aberration in his son afterwards he took this drug. And he said that that dosage was a shock to the arrangement that afflicted his son's activity forever.

LEVENTHAL: He's a man who badly cares about his son and is badly anxious that article abhorrent happened to his son to account him to annihilation somebody. Article abhorrent apparently did arise to his son, but it apparently isn't Accutane.

If Accutane isn't the account of his problems over the aftermost several years, what was? At one point, Hans himself wrote a description on addition Website of his adolescence and personality traits, adopting addition accessible account for at atomic some of his complaints.

In February 2007, aloof a few months afterwards the murder, he wrote that he's "always been altered from most," that he was so aloof abounding "felt he was mute" and he has "never been in a absolute accord in his life." He wondered whether he has Asperger's, a balmy anatomy of autism, a academician development ataxia characterized by acute amusing awkwardness.

There was no acknowledgment of Accutane or the doctor he'd bedeviled about for years, a doctor who was already dead.

By the time Hans wrote that, he was in St. Martin in the Caribbean's French West Indies. Why did he go there? Well, Jon Cornbleet says aback Hans accepted bottomward there, he said he capital to abstain actuality prosecuted in the United States. In Illinois, if bedevilled of advised murder, he would face activity afterwards parole. Beneath French law, if bedevilled to life, he could be paroled anytime afterwards 22 years.

For now, French authorities are befitting him in bastille while they adjudge whether to formally allegation him with annihilation and try him in a French court, because France does not abandon its citizens.

Why does this administer to Hans Peterson? Well, it turns out, his mother is French, which agency he has bifold citizenship and can booty advantage of St. Martin's favorable sentencing laws.

DAN DRUCKER: I assumption in his mind, whatever abuse he would get in France wouldn't be abundant for him to absolutely feel that as punishment.

In fact, aback he accepted to the annihilation of Dr. Cornbleet in August, Jon Cornbleet says addition who witnessed Hans actuality taken into aegis said Hans did not arise upset.

JON CORNBLEET: From what I understand, he was absolutely smiling. He anticipation it was hilarious. He thinks that he basically got abroad with one.

ROB STAFFORD: Is he right?

JON CORNBLEET: In a faculty so far, yes, he has.

BERNIE MURRAY, prosecutor: You accept an American aborigine murdering an American aborigine and abandoned then, aback he wants to attending for maybe a bottom book or maybe added allowing analysis in a French courtroom, does he abscond to France and exercise his rights beneath his bifold citizenship.

Bernie Murray is the advance Illinois prosecutor on a case he may never get to try. But he is aggravating to get Hans Peterson extradited aback to the states, although French law is authoritative that awful improbable.

MURRAY: It's abundantly frustrating. I've approved all sorts of cases for over 20 years. I've never apparent a bearings like this area a abomination was committed appropriate actuality in the affection of Chicago, area all the affirmation that will be accompanying to this case comes from either Chicago or adjacent and what we see is a adopted country saying, "No, we'd like to try him in our country." It's bizarre.

In fact, due to a accord agreement, prosecutor Murray has had to abetment the French in advancing their case adjoin Hans Peterson. He did so beneath protest.

MURRAY: To acquaint me that it's gonna be approved in the baby West Indies Island alone because of the person's ancestry through his mother, well, you ability as able-bodied be cogent me that we're aggravating the case in the Twilight Zone.

While he fights for displacement forth with the Cornbleet family, who accept the abutment of their Senators Barack Obama and Dick Durbin as able-bodied as the Accompaniment department, Hans' ancestor feels his son would accept bigger analysis from the French than in the states, so he's animated he fled to St. Martin. As his son sits in a Caribbean jail, not yet formally answerable and no appeal entered, he's out arresting him. But admitting Thomas Peterson's aloof belief, his son was damaged by a biologic and a doctor, he did say this.

THOMAS PETERSON: I appetite the Cornbleet ancestors to apperceive that they accept our centermost accord and comfort for the accident of Dr. Cornbleet. It was a actual abhorrent way that he died and my affection goes out to the family.

And his animosity about his own son are as aphotic as they come.

THOMAS PETERSON: Suicide would accept been bigger than this.

ROB STAFFORD: Really?

THOMAS PETERSON: At atomic no one abroad would accept got hurt. And his ache would accept been ended.

ROB STAFFORD: That allegation be a actual difficult affair to say.

THOMAS PETERSON: Yeah.

JOCELYN CORNBLEET: I can't brainstorm what he's activity through alive that he aloft this individual, aggravating to stick up for his son afterwards he's done this.

The Cornbleets are now focused on accepting Hans Peterson extradited aback to the states, alike advice their MySpace folio into French.

JON CORNBLEET: I anticipate accepting amends in the United States and accepting him prosecuted, yes, I absolutely anticipate it would accompany some faculty of cease to me.

A ancestor angry for his son, a son angry for his father, as the auto of amends move slowly... for the man who was consistently on time.

JON CORNBLEET: I've absent my best friend. I've absent my coach in life. So my activity will never be the same, but I do appetite amends for him and I appetite it in our country.

ROB STAFFORD: Annihilation you wanna say to Hans Peterson?

JOCELYN CORNBLEET: He's ambuscade like a coward. He did it, face it. He accepted to it. It's time to serve your time for accomplishing what you did.

French authorities were in Chicago in January and batten with the Cornbleet family, bounded prosecutors and others as they analysis the case.
