Dorothy Otnow Lewis is an American psychiatrist and author who has been an expert witness at a number of high-profile cases.
She specializes in the study of violent individuals and people with dissociative identity disorder (DID), formerly known as multiple personality disorder. Lewis has worked with death row inmates as well as other prison inmates convicted for crimes of passion and violence, and was the director of the DID clinic at Bellevue Hospital, associated with New York University in New York City. She is a professor of psychiatry at Yale and New York University and is the author of Guilty by Reason of Insanity, a book she wrote based on research done in collaboration with neurologist Jonathan Pincus.
Lewis, born in 1938, is a graduate of the Ethical Culture Fieldston School, Radcliffe College and Yale University School of Medicine. This was an unusual achievement for a woman of her generation. She has stated in one of her books she originally went to medical school intending to become a psychoanalyst. [1]
She was married to Melvin Lewis, a child psychiatrist and professor at Yale, who died in 2007. She has two children.
During her research Lewis concluded that most, if not all, of the inmates she worked with had been abused as children or had experienced or witnessed potentially traumatic events, including violence. She found that in most cases both the accused and the family members have been reluctant to discuss the abuse that happened in the past; in many cases she concluded that the inmates had blocked out the memories. [1] In some cases she was able to find testimony to this abuse as well as corroborating evidence. The corroborating evidence often included scars said to be from the abuse, as well as hospital and criminal records potentially related to abuse. In many cases, the hospital records of the abuse were attributed to other causes, often accidents; the explanations often did not match the injuries according to Lewis, however. [2] She also found that the parents of these children often had the same problems as the children and concluded that they taught their behavior to the children. She argued that they often relied on excessive force to discipline their children and used it inconsistently, and that in many cases the children who received the strictest discipline became the most violent. [3] In some cases these children found that if they told other adults about the abuse, which in some cases was very extreme, they found that adults didn't believe them because the stories were too bizarre. [4]
However, other experts, such as forensic psychologist Barbara R. Kirwin, question Lewis' uses of small samples without control groups, and her own findings indicate a far lower estimate of how many murderers were abused as children. [5]
Lewis in fact focused on several possible antecedents of violence, and summed up her conclusions in 1998: "What brain damage does is it increases emotional lability, impulsiveness, poor judgment. But most brain-damaged people are not violent. And psychoses, even paranoia ... even paranoid schizophrenia does not usually create violence. Most people with this disorder are not violent. And probably abuse alone does not create a grotesquely violent individual. However, when you put these together brain dysfunction, a tendency to paranoia and early on-going horrendous abuse and violence, you get a recipe for violence." [6] Lewis has also highlighted the role of extremes of mood such as major depression and mania or even hypomania (including swings between them as found in the bipolar spectrum, previously known as manic depressive psychosis), and dissociative identity states (formerly multiple personality disorder, that Lewis originally doubted the existence of).
Lewis has assessed and/or testified for the defense on several high-profile criminal cases, including Mark David Chapman, Joel Rifkin, David Wilson (Louisiana) and Marie Moore (New Jersey), [7] Joseph Paul Franklin, Ted Bundy and Arthur Shawcross. She most recently testified as an expert witness for the defense in CO vs. Letecia Stauch for the disappearance and murder of Gannon Stauch in May 2023. Her testimony mainly benefitted the prosecution, however. The jury did not find her testimony to be credible and Stauch was found guilty on all four charges. [8]
In the Shawcross case, Lewis was the subject of some controversy. The first defense psychiatrist had concluded there was no insanity defense feasible for Shawcross, but Lewis reported diagnoses of post-traumatic stress disorder, dissociative identity disorder, brain damage, and psychomotor epilepsy. However, the prosecution took her case apart and it appeared that she had obtained some of her interview material from Shawcross by hypnosis, conducted without proper procedures for protecting against leading questions and false memories. In turn Lewis criticized the defense team for failing to obtain further brain studies to verify diagnoses of epilepsy and brain damage. She questioned the ethics of a prominent neurologist who was sent a brain scan by the defense and who ended up using the brain scan to testify for the prosecution. While Lewis stated that her long-term colleague Pincus found evidence of a temporal lobe cyst, frontal lobe scarring and electroencephalogram spiking, other neurologists found no evidence of abnormal ECG readings or any witnessed seizure, and concluded his neurology was within normal limits. [9] Over the course of the trial Lewis became the focus of some public ridicule for her rambling style, and afterwards some of the jurors said she had damaged the defense case. [10] Lewis has proposed a conspiracy theory to explain why she may have been deliberately undermined, based on the prosecutor sharing the same rare name as a former CIA operative and the possibility that her questioning of Shawcross's army days might have risked revealing he had been put through MKUltra-type brainwashing experiments. [11]
Lewis was also hired by the defense for the Washington Beltway Sniper John Allen Muhammad and assessed his mental state. Her report concluded that he had psychotic schizo-affective disorder and had brain dysfunction. [12] Lewis, along with a New York Times journalist who reported an interview with her prior to Muhammad's capture, has been criticized by the head of the American Psychiatric Association and National Alliance on Mental Illness for having asserted that the man is "clearly psychotic" and probably manic. Lewis defended her media work and referred to another article that said she was one of the few to have gotten it right; however, for that Newsweek article she was quoted: "He may be talking nonsense, but that doesn't mean he's delusional." [13]
Lewis is skeptical of the death penalty, but not necessarily the sentencing of inmates to life in order to protect the public. Neither Lewis nor Pincus believe the death penalty works as a deterrent. Lewis believes that the quest for justice often leads many prosecutors, judges, jurors to overlook things that could be considered mitigating circumstances. She believes that this leads to overlooking the root causes of crime and prevents long-term solutions that will help reduce child abuse and prevent more abused children from becoming killers. [14]
In 2004 Lewis alleged that British playwright Bryony Lavery's hit Broadway play Frozen , particularly the character of 'Agnetha', a psychiatrist sent to evaluate a serial killer, was based on thematic similarities with her book Guilty by Reason of Insanity and verbatim extracts from a New Yorker article about her by Malcolm Gladwell. Lewis hired a lawyer and began preparing for a lawsuit, including getting Gladwell to sign his copyright over to her for her case. The story was covered internationally in 2004 and Lavery states it has damaged her career. However, Gladwell himself has since said he was not comfortable signing over his copyright to Lewis (and did change his mind) and, while understanding that she was upset, suggests that the legal accusations were fueled by a lack of appreciation of the creative arts. [15]
In 2020 Lewis' work on the psychology of murders was portrayed in the documentary film Crazy, Not Insane by Alex Gibney.
The insanity defense, also known as the mental disorder defense, is an affirmative defense by excuse in a criminal case, arguing that the defendant is not responsible for their actions due to a psychiatric disease at the time of the criminal act. This is contrasted with an excuse of provocation, in which the defendant is responsible, but the responsibility is lessened due to a temporary mental state. It is also contrasted with the justification of self defense or with the mitigation of imperfect self-defense. The insanity defense is also contrasted with a finding that a defendant cannot stand trial in a criminal case because a mental disease prevents them from effectively assisting counsel, from a civil finding in trusts and estates where a will is nullified because it was made when a mental disorder prevented a testator from recognizing the natural objects of their bounty, and from involuntary civil commitment to a mental institution, when anyone is found to be gravely disabled or to be a danger to themself or to others.
The abuse defense is a criminal law defense in which the defendant argues that a prior history of abuse justifies violent retaliation. While the term most often refers to instances of child abuse or sexual assault, it also refers more generally to any attempt by the defense to use a syndrome or societal condition to deflect responsibility away from the defendant. Sometimes the concept is referred to as the abuse excuse, in particular by the critics of the idea that guilty people may use past victimization to diminish the responsibility for their crimes.
Mark David Chapman is an American man who murdered English musician John Lennon in New York City on December 8, 1980. As Lennon walked into the archway of The Dakota, his apartment building on the Upper West Side, Chapman fired five shots at the musician from a few yards away with a Charter Arms Undercover .38 Special revolver. Lennon was hit four times from the back. He was rushed to Roosevelt Hospital and pronounced dead on arrival. Chapman remained at the scene following the shooting and made no attempt to flee or resist arrest.
William Stanley Milligan, also known as The Campus Rapist, was an American man who was the subject of a highly publicized court case in Ohio in the late 1970s. After having committed several felonies including armed robbery, he was arrested for three rapes on the campus of Ohio State University. In the course of preparing his defense, psychologists diagnosed Milligan with dissociative identity disorder. His lawyers pleaded insanity, claiming that two of his alternate personalities committed the crimes without Milligan being aware of it. He was the first person diagnosed with dissociative identity disorder to raise such a defense, and the first acquitted of a major crime for this reason, instead spending a decade in psychiatric hospitals.
Bobbie Jo Stinnett was an American, 23-year-old, pregnant woman who was murdered in Skidmore, Missouri, in December 2004. The perpetrator, Lisa Marie Montgomery, then aged 36 years old, strangled Stinnett to death and cut her fetus from her womb. Montgomery was arrested in Kansas the next day and charged with kidnapping resulting in death – a federal crime. Stinnett's baby, who had survived the crude caesarean section, was safely recovered by authorities and returned to the father.
Arthur John Shawcross, also known as the Genesee River Killer, was an American serial killer active in Rochester, New York from 1972 through 1989. Shawcross's first known murders took place in his hometown of Watertown, New York, where he killed a young boy and a girl. Under the terms of a plea bargain, he was allowed to plead guilty to one charge of manslaughter, for which he served 14 years of a 25-year sentence.

Settled insanity is defined as a permanent or "settled" condition caused by long-term substance abuse and differs from the temporary state of intoxication. In some United States jurisdictions "settled insanity" can be used as a basis for an insanity defense, even though voluntary intoxication cannot, if the "settled insanity" negates one of the required elements of the crime such as malice aforethought. However, U.S. federal and state courts have differed in their interpretations of when the use of "settled insanity" is acceptable as an insanity defense and also over what is included in the concept of "settled insanity".
Neurocriminology is an emerging sub-discipline of biocriminology and criminology that applies brain imaging techniques and principles from neuroscience to understand, predict, and prevent crime.
Shawn Michael Grate is an American serial killer and rapist who was sentenced to death for the murders of five young women in and around northern Ohio from 2006 to 2016.

On November 21, 1987, 19-year-old Kathy Carol Bonney was killed by her father Thomas Lee Bonney in Camden County, North Carolina. The case gained media attention not only due to the brutal manner in which the killing had been carried out, but also because Tom Bonney pleaded not guilty by reason of insanity on the grounds that he had dissociative identity disorder and that an evil personality state was in control at the time of the killing. The book Deadly Whispers by Ted Schwarz and a television movie of the same name are based on the case.
