Cross-country cold case leads detectives to Chicago-area Tylenol murders
ABC7 Chicago • • nation
Key Points:
- Idaho investigators have identified Dr. Matthew Betkouski, a chemist with a history of mental illness, as a person of interest in the 1982 Tylenol murders, though there is no evidence placing him in Chicago at the time of the poisonings.
- Betkouski, who died by suicide in December 1982, allegedly made comments about using poison in capsules and committing the "perfect crime" during his employment at various companies.
- The Tylenol murders resulted in seven deaths from cyanide-laced capsules in the Chicago area, leading to a massive product recall and changes in medication packaging to include tamper-proof bottles.
- Chicago and Arlington Heights police are reviewing the new information from Ada County, while the FBI cautions against drawing conclusions until evidence substantiates any claims.
- Family members of victims, like Michelle Rosen, urge transparency and public release of investigative records to further examine Betkouski's potential involvement.
