Who Was Dr. Mathew Betkouski? Man Linked to Unsolved 1982 Tylenol Murders
"The identity of the Tylenol killer from 1982 can be shared,” forensic psychiatrist Dr. Park Dietz told reporters.
In 1982, a series of seven unsolved poisoning deaths occurred in Chicago, known as the Tylenol murders. Organic chemist Dr. Mathew Betkouski, who struggled with mental illness, is now being investigated for possible involvement in the crimes. Betkouski's body was discovered inside Sacred Heart Catholic Church in Boise on December 4, 1982, with $1,900 in cash and a suicide note signed "Wm. L. Toomey." The note referenced a cyanide capsule he had taken.
Despite the note and his background, Ada County Sheriff Matt Clifford stated that Betkouski has not yet been named as a suspect in the Tylenol murders or placed in Chicago during the time of the poisonings. However, Chicago police have been provided with information by investigators, including some not revealed during the press conference.
Dr. Park Dietz, a forensic psychiatrist who worked on the initial investigation, believes that the case against Betkouski is strong. He noted that Betkouski's connection to the Tylenol murders is extraordinary, as he was alive in Chicago during the time of the homicides and is now identified as a likely suspect. Betkouski's mental health issues, including schizophrenia, depression, and paranoia, may have contributed to his actions, as well as a cascade of stressors including the death of his mother, loss of his job, and a failed invention presentation.
The Tylenol murders have since led to the creation of tamper-proof bottles to prevent similar incidents.
