Michael Mark Welner (born September 24, 1964) is an American forensic psychiatrist and Chairman of The Forensic Panel. Welner is best known for his work in sensitive and complex litigation. He has acted as lead forensic psychiatric examiner in numerous criminal or court proceedings of national and international prominence, including precedent-setting trials and higher court decisions. Welner is also known for a number of innovations in forensic science, forensic psychiatry and justice, including protocols for prospective peer review in forensic medicine consultation, research to standardize an evidence-based distinction of the worst crimes, The Depravity Standard, and recommendations for upgrading forensic science assessment. He has been featured in network television news coverage of forensic psychiatry issues, has authored publications for professional and public audiences, and has contributed to emerging legislation on mental health reform.

Notable cases

Welner is best known for his role and impact in a range of legal cases within the criminal and civil courts. Those of particular prominence or legal significance include:

State of New York vs. Pedro Hernandez – Etan Patz disappearance and murder

Nearly 40 years after Etan Patz disappeared, Pedro Hernandez was arrested in connection with his kidnapping and murder. Prior to Hernandez' arrest and a relative's revelations about his confessions, many authorities believed that Jose Ramos, convicted of other sex crimes, was responsible for Etan Patz' disappearance.

Prosecutors first involved Welner at the early stages after the arrest, before filing charges, to consider defense claims from several psychologists that Hernandez was mentally ill and intellectually disabled and falsely confessed. The defense presented multiple expert opinions in support of their claims that Hernandez was and that his confessions were unreliable. Welner interviewed Hernandez for sixteen hours, interviewed police, studied confessions he had made many years earlier to a prayer group and to a fiancée, as well as to an acquaintance, and the more recent confessions he made to police interrogators in 2012, medical staff, as well as Welner himself. Welner concluded that Hernandez confessed because he felt intense guilt and that the spontaneous, voluntary confessions Hernandez made decades earlier to a prayer group and his fiancée couldn't be attributed to a psychiatric condition.

The case proceeded to trial in 2015. Eleven jurors voted guilty, with one holdout juror remaining after nearly three weeks of deliberation. Welner testified for prosecutors at the original trial and then at the retrial, in which a jury unanimously rendered a guilty verdict to Hernandez in early 2017. Among other points, Welner told jurors it was possible Hernandez tried to minimize the damage he'd done even though he confessed. "It is not remarkable at all for a person to recall a sequence of events and to portray it in a way that is as unremarkable as possible, scrubbing away details … (creating a) much more detached relationship between that person and a victim."

U.S. vs. Brian David Mitchell – Elizabeth Smart kidnappers – Sect Psychology and Brainwashing

Brian David Mitchell, a self-proclaimed prophet, was charged along with his wife in connection with the 2002 kidnapping of Elizabeth Smart. In a case involving the complexities of determining religious zeal from psychosis, Mitchell had been found not competent to stand trial in 2005. Mitchell then began a consistent pattern of singing hymns in court and silence to forensic examiners.

Subsequent evaluations in a state hospital, with which Mitchell did not cooperate, deemed Mitchell to be unchanged – and therefore incompetent. Three years passed, and the case was contemplated for dismissal in state court when federal prosecutors asked Welner to study the matter to a definitive end. He filed a 206-page report detailing extensive new information uncovered in his evaluation, and testified to his conclusions that Mitchell was competent. At a 2010 hearing, Justice Dale Kimball ruled Mitchell was competent to proceed.

The case proceeded to trial, where Welner testified that Mitchell was a pedophile, a sadist, personality disordered, and not legally insane. His testimony drew particular attention to cognitive distortions as they differ from delusions, and culture-specific beliefs of fundamentalist LDS adherents. Mitchell was convicted and sentenced to life in prison. The defense waived its right to appeal.
