New Study Shows 92% Of Convicted Murderers Suffer From Aspergers Syndrome

92-percent-murderers-diagnosed-aspergers-wit-scienceThe Wyoming Institute Of Technology‘s very own, Dr. Franklin Forrester, will be published in next month’s American Journal of Medicine. The essay details recent findings from a seven year study which focused on convicted murderers who have been diagnosed with Aspergers syndrome.

Dr. Forrester and his team of psychiatric professionals, doctors and criminal psychologists interviewed over two thousand different prisoners, in seven different states. The group focused on the correlations between autism, and criminal offenders. What they found shocked everyone.

The following is an excerpt from the AMJMED article due out next month.

“My inspiration for this study was the tragedy that took place on April. 16th 2007, and is widely refereed to as the Virginia Tech Massacre. Seung-Hui Cho, took the lives of 32 students and wounded 17 others. He had been diagnosed with autism as a child, and after watching the video he released prior to the killings, I felt this was an accurate assessment.

I began my research in the fall of 2008. I initially financed and managed the launch of the project. A year later I was fortunate enough to receive multiple generous government grants in order to continue the study. The inquiry has been my primary focus for the past 7 years.

These travesties have become common place in today’s news, and are occurring with an unsettling frequency. This study has enabled us to outline the distinct interconnections between autism and manslaughter, we hope that ultimately, this study will provide professionals with the information they need in order to intercept potential offenders before tragedy strikes. Our goal is to save lives.

After conducting extensive interviews with 2,342 prisoners, and evaluating the psychiatric histories of another 10,000 inmates, we were able to conclude that roughly 92 percent of murderers fell somewhere within the high-functioning autism spectrum.”

In the full essay, Dr. Forrester goes onto describe the scientific methodology behind his study, as well as releasing further data, and proposes several solutions to the epidemic.

The issue will hit stores July 12th, 2014.

    this article is dangerous as it adds to the negative views of those on the Autistic Spectrum. I accept that SOME of those in prison for murder and other offenses are on the spectrum, BUT that can be said of any group of people, if the article focused on race saying a high percentage of a murderers are of a certain racial group, there would be an out cry and the scientist and those who printed the article would be branded as racists (quite rightly) and yet saying that in a SMALL sample a high percentage of murderers were on the Autistic Spectrum and as a result they are implying that a high percentage of ALL murderers are on the Autistic Spectrum seems to be fine. IT IS NOT FINE !!! HATE AND BIAS AGAINST A GROUP WITH A CONDITION LIKE ASD IS STILL HATE AND BIAS AND CAUSES DISCRIMINATION AND THAT IS A CRIME.

    As someone who is on the spectrum with other family members on the spectrum including my son, I am scared that this article and others like it could make my son’s life more difficult.

    If you MUST make generalisations about a group of people then say MANY of those who “thought differently” and made discoveries and inventions both past and present, like Newton and Steve Gates are or were probably on the Autism Spectrum and the world is a better place for ALL as a result of those who thought differently.

      Hello Dr. Forrester,
      I am commenting on an article that you wrote/published in the Wyoming Institute of Technology: “New Study Shows 92% Of Convicted Murderers Suffer From Aspergers Syndrome , By Dr. Franklin Forrester on June 27, 2014. I am the parent of a sixteen-year-old girl with Asperger’s syndrome, and I found the title and tone of the article somewhat offensive. Professionals and researchers have to be very careful of the context here. There is absolutely no scientific evidence that Asperger’s syndrome is the cause of homicidal behavior. While this may be correlative to some degree (such as the autistic relational claims to schizophrenia), you know as well as I do, that there are a complex number of emotional, social, and psychological aspects that can mix and lead into a specific psychological trigger. Proceeding with these kinds of claims, and their interpretations requires extreme caution as to cause and effect.

      I would want to know if your research team screened their subjects for a host of many other psychosocial and biological traits / variables, as well as early childhood influences and the environmental situ that these people were afixed and associated with, and how you and your colleagues arrived at their diagnostic criteria and certainties. I know a lot of families who care for autistic spectrumed children, who would find this kind of blunt claim offensive, since the majority of these misunderstood and wonderful individuals have never displayed psychopathic tendencies. Oh, by the way, I am a trained Criminal Profiler.

        I feel that this study may be wrong. I doubt if they also included car crashes and things like that, because those who run someone over would be convicted of murder, and there are alot of things like that. I doubt many of them would also have aspergers.

    • Natalie Holder

      August 30, 2014 at 8:41 am

      As someone with Aspergers I think the study should include how we are treated by the our families, our communities, and our peers. I was abused, raped multiple times and no one believed me. I was subject to all kinds of abuse both as a child and an adult. I did not become violent or consumed with rage. I became a writer and an activist trying to comfort and give support to others experiencing the abuse because they perceive the world differently. This article does not mention the environmental context in which these acts of violence occur. And I fear this kind of thinking will only justify the stigma and abuse we face as we try to create lives for ourselves and function in society in a meaningful way.

        So sorry that happened to you Natalie! I couldn’t agree with you more! Children on the spectrum are often highly stressed without added abuse, etc…

        Nonetheless, I think this “studies” claim is hogwash! I’m sure there are Plenty of things they didn’t take into account & I think they went into the study with a negative mindset due to the tragedy that triggered there study!

      Thank you for this comment! I have to agree: much of the world has been pathologizing or even demonizing Autistic Spectrum Disorders. And it was going to happen, that a “connection” between crime and ASDs would be made. As a woman in her 20s on the spectrum (diagnosed with Asperger’s under DSM-IV), I can’t help but cringe and wince and wonder: Who the hell is going to listen to US, the people with first-hand experience, the people who experience and live with it every single day of their lives in a way that their family/guardians/advocates don’t?

      I am asking people now: The most important voices to be heard are OURS, the ones on the Autism Spectrum. We do need help sometimes. We do need supports, and to be understood. Just listen to us; the answers don’t always come from doctors and “experts” and organizations like A$, but from us.

      If this study is accurate — and we have no proof that it is — then it suggests that non-Autistic/Aspergers murderers were canny enough to hire competent lawyers, or clever enough not to get caught.

    The doctor and other professionals involved in this study should have question the patients diagnosis. I and many other living with FASD affected individuals believe that UN-diagnoses, UN-treated or misdiagnosed individuals exposed to alcohol in-utero are more likely to be in jail for repeat crimes. Fetal Alcohol Spectrum Disorder are the number one preventable cause of mental health issues, cognitive impairment and social disorder……I think this study missed the boat.

  3. Edward Judd

    June 28, 2014 at 6:46 am

    I’m sorry but this will only fuel unnecessary stigma against the Asperger’s community. Wouldn’t a MUCH better study would be to find out how many of those with Asperger’s Syndrome are convicted murderers? Not the other way round which is completely and utterly stupid.

    Further research should be done on this. The Aspies I know wouldn’t hurt a fly! The question shouldn’t be to see if they have autism. How were they treated while growing up, research their background. They are not in prison because of autism… They have been convicted because they broke the law…Autism has nothing to do with it!

      I have 2 sons with Aspergers both doing very very well and living productive and happy lives. Any problems they’ve ever encountered has come from other people’s misconceptions and ignorance.
      So thanks a lot “Doctor”, as if kids with Aspergers don’t get bullied enough without this !!

    I’m curious to know if Fetal Alcohol Syndrome was included as a possible disorder among these folks as well. I have a hard time believing it is Aspbergers if FAS wasn’t even considered. FAS seems more likely since it most always causes damage to the parts of the brain that controls behavior, and specifically behaviors that involve self-control, impulsiveness and regard to rules/authority.

  6. Alyssa Âû

    June 28, 2014 at 10:19 am

    I agree with most of the other comments… I myself have AS and know many people on the spectrum. While I have seen things like emotional problems associated with Asperger’s, they don’t usually influence aspies to act violently unless there are other mental health issues involved, or other environmental factors. Aspies are prey animals and are more likely to be victims than offenders.

  7. Elaine McLeod

    June 28, 2014 at 10:24 am

    Seriously! This is bull pucky! So you’re saying that only 8% of everyone in jail are psychopaths, sociopaths, have other mental illnesses or committed crimes of passion. That doesn’t add up. There are many similarities in mental illnesses and mental disorders and it’s all in how it is perceived. If you set out to demonstrate that 92% of the murderers were psychopaths you could do that too. Just because one person with Autism commits a crime it doesn’t mean that all criminals are Autistic. This is stereotyping at it’s finest. Let’s create more stigma in an already judgemental world!

  8. VJ West

    What kind of a scientist makes a catalogue of diagnosis but not a catalogue of the mind altering drugs these killers are consuming? Since the DSM V eliminates “Asperger’s Syndrome” that’s 7 years down the drain for trumping up a connection to a diagnosis that doesn’t exist. Back to the drawing board! Try a catalogue of psychotropic use next. Might be much harder to get funding since the manufacturers are the ones who throw out the cash, but at least that isn’t a factor eliminated with a stroke of a pen.

    I think rhe Doctor that did this study needs to be educated on Autism more espeacially aspergers. I happen to jave aspergers and am very much a God fearing Christian and could never hurt another human in rhe fashion mentioned or otherwise. If one has aspergers and commits a crime like murder there is more involved than just that qeather it be spirirual or another mental condition with it or even a mix of the two. Stop pointing and blaming asperbergers for everything and look at the whole picture. Is or was rhe person doing drugs? Were they drinking alchol at the time? What other mental problems did they have that those thing might have enhanced, aspberger and other forms of autism do not cause one ro do these things, its lije anyone else its a matter of choice and cosequence just lije anyone else so stop teying to say its just one group or one mental disability or the other a bad person is a bad person. Focus on that. And get better educated on high funtioning autism before running your mouth and making us innocent ones look bad becuase of some else’s choices and actions.

    I am shocked and disgusted by this “study.” How dare someone attempt to say that all serial killers are on the Autism Spectrum. There are many people on the Autism Spectrum. Each of them is an individual. I, myself, have a diagnosis of Asperger’s, and I know countless others who are also on the spectrum. The degree of hatred that is currently being projected on to this community is shocking and disturbing. I am further offended by someone who insists that he is making diagnostic claims about how Asperger’s is such a dangerous threat to the world when, frankly, the Asperger’s experience is not his experience. Why not also assess other elements, such as drug abuse, mental illness, other medical conditions, etc. Why is it just this ONE diagnosis? I smell an agenda here!

  13. Amy

    June 28, 2014 at 3:18 pm

    This is done through bad science. First who is diagnosing many of these prisoners? The doctor who is gaining from the study? Second, have there been other studies in other prisons to support the findings of this particular study. Lastly, as a previous poster commented, this does not account for those living on the spectrum who are not in prison or convicted of a crime. It leaves out a large piece of the population and makes assumptions based on one persons ideals. Again, bad science.

    The media that reports misinformation and speculation have created the stigma on persons with mental health issues, usually pointing a “supposed correlation” to autism. This, in my opinion is RACIST against all people living with autism. Reports like this plant a suggestion in society’s mind and they roll with it. You cannot accuse someone of being a criminal or dangerous because they are autistic. This is worse than the “Refrigerator Mother” theory causing autism. Take your biased study and throw it out.

    This article is full of shit. Our children on the spectrum don’t need to hear this crap. They have a hard enough time with acceptance as it is. Now they will be viewed as possible school shooters and will be isolated even more. I’m bipolar and I’m tired of hearing all the bad press and assumptions that we are killers in waiting. This stuff hurts those of us with mental illness. I’m treated differently since my diagnosis and I’m sure it has to do with all the recent violent attacks committed by people who are bipolar. I am anything but violent. And my son is the sweetest, kindest, loving boy. Mental illness can really mess you up. Left untreated it can cause some disturbing behavior. I personally believe that environment makes a huge difference too. Without treatment and a strong support system makes the illness that much more difficult to handle. Please don’t give up on our kids. Children with asperger’s have a lot of potential to be successful. This article tells them they cant

      You’re are just in denial because you don’t want to hear it. This stuff is important for research to avert unwanted behaviors and understand the non-neurotypical mind better. Just because you have children on the spectrum doesn’t mean you know what goes on in their heads. Instead of ignoring what has been revealed, you can use it as a basis of research to help Aspies integrate better in society and protect Aspies from harm that could create a backlash.

    I have a son with Aspergers. I lead a support group for adults with Aspergers. I know a large number of people with Aspergers. The only common trait I consistantly found was that those of us with Aspergers are extremely hard on ourselves. We all are empathetic – we feel the emotions of those around us. We are NOT violent. When we get overwhelmed, we don’t lash out at others, we escape from others. Maybe 92% of murderers fell somewhere on the spectrum (or maybe they were just anti-social – NOT THE SAME THING) but regardless, Aspergers/Autism did NOT cause them to murder. I can guarantee that if you dug futher, you would find that each one of the 92% also suffered from some other phsychotic disorder like schizophrenia or bipolar, etc. I urge you and others to stop the assualt on autism/Aspergers. We are not deseased. We are different but not less. We are humans. We have feelings and emotions. We care. We love. We laugh. We cry. We might not show our emotions in front of you. But we do have them. We are too judgemental of our own actions to be able to kill innocent people.

    If this study is true: that (holy, freaking cow!) 92% of all convicted murderers are on the autism spectrum to some degree or another, and if other similar studies can corroborate and verify the conclusion of this study as a fact, then, why isn’t the news getting out to the public? This is whopping big news.

    I was more likely to believe that most convicted murderers (murderers of individuals, or of their families, or coworkers, or of masses of strangers) probably have schizophrenia or one (or more) of the Cluster B personality disorders, or psychopathy, so I am quite surprised that autism spectrum disorder is evident in such an incredibly high percentage of convicted murderers.

    I would like to see other independent, corroborative studies first, before I accept this as gospel, so to speak. But if its true, then we can have a chance to make a significant, positive difference in murder rates by focusing our limited financial resources on the autism spectrum disorders and getting much-needed help/treatment for those on the Autism spectrum much earlier in their lives.

    No, No, NO! Please be more careful in how such correlations are reported, and in how things are presented to public media. Perhaps people who are psychotic sociopaths ALSO happen to have some autism traits. Putting that there are several other correlations – white male, teen/young adult, certain parenting traits at home, etc. There are millions of autistics/Aspergers folks who wouldn’t hurt anyone. PLEASE get an ethics clue about how these things are reported. This sort of thing fuels horrible bias against a large majority of people who are not threats to society.

    The Aspies tend to deny it because they can only relate to personal experience. Therefore they believe what goes for them goes for every Aspie. While many sources point out that people with Aspergers are more likely to murder, are more likely to be victims, commonly get out of jail early (due to good behavior), etc. It must be further examined to filter out inconsistencies. My recommendation to prevent such murders and get that rate down to NT levels is to develop intervention, spread awareness to prevent Aspies from being abused, ensure an Aspie friendly environment, because commonly if Aspies get abused long enough or get together with the wrong people, something is bound to happen.

    June 6, 2015 at 10:25 pm

    And it should be noted here that nobody is born evil, evil is what society made them to be. I have an understanding of what could drive people to terrible crimes like murder, and worse. And do you know why, at the very heart of the matter, they do it? Because of perception. If you spend your whole life isolated, shunned, rejected, being different can change your perspective. In only ways that someone who has been a victim for decades understands, I know why many of them did what they did.

    The sad thing is, people are very predictable. And by posting this study, people will correlate autism with this now. And that means further isolation, further shunning. By human nature itself, the odd an unusual is scorned. But if you add in the element of fear… You could be the cause of many people with autism to be hurt very badly. Did you think about the implication of this study? Or do you care? Maybe making a name for yourself is more important than the safety of innocents who already struggle in this world. Or maybe you never gave it a thought.

    I am on the autism spectrum, and I’ve never murdered anyone. But how many people, seeing my oddness, will now be afraid because of this article, this little study of yours. I could tell you that 99% of all criminals are criminals because of faults in society, but would you believe that you contribute to these faults through blind conformity to the “norm”? I believe the results of this study, I do. But I also believe that a vast majority of the public is too stupid to use this information in any sort of constructive way. So I have to ask, just what are your motivations here?

    Do you know what it was like for me, what it is like for me? Do you have any idea how much worse it would be if the results of your study were common knowledge? There’re no words grandiloquent enough to properly convey the struggles brought on by isolation, mistreatment, ignorance, and “justified” vindictiveness of the normal person. The people who create monsters are the real monsters. And you, you are a monster. How many children will suffer because of your study? How many will kill themselves? How many people will feel even more isolated, even more misunderstood, all because you did a study to confirm what many of us already suspected. It’s what drives people to such acts that is the problem. And you’ve certainly done a fine job in contributing to the stigma and hardships of autism. Bravo.

    July 6, 2015 at 8:30 am

    This… This article is terrible. As others have said before, no other aspects of the criminals’ lives have been taken into account. Having Asperger’s Syndrome does not make you more likely to commit crimes.

    If this study does have accurate results (which I seriously doubt), it isn’t the Aspergers itself that’s caused this percentage. It’s how those with Aspergers have been treated differently to those without. This article is just separating Aspies and Typicals farther, making them even more likely to commit crimes.

    This article doesn’t mean much to me because of the way it was done. If you go to a prison and find that most prisoners have a prison uniform, does that mean that most prisoners wore a prison uniform before going to prison? No, it means most were given the uniform while in prison.

    Just because 92% of prisoners exhibit signs of Aspergers, that doesn’t mean that 92% of those people exhibited those same signs before prison. It could mean that prison itself is causing them to exhibit those signs.

    For another example, lets say that 200 people went to Azkaban, that Harry Potter prison with dementors that make you experience your worst memories constantly. Three years later, each of the prisoners are interviewed, and a study comes out showing that 92% of them are traumatised wrecks. Would you believe that any significant number of them were wrecks before Azkaban? I doubt it.
