Theresa M. “Terri” Tarasewicz Janus, a 20-year-old Caucasian woman from Arlington Heights, Illinois, tragically lost her life on September 29, 1982, in what became known as the infamous Tylenol poisonings. Theresa had recently married Stanley Janus on June 19, 1982, and the couple was in the early stages of building their life together. She was known for her intelligence and ambition, having pursued a business degree at Illinois Benedictine College.
Her nurturing nature made her a beloved member of her family and community.
On the day of her death, Theresa and her husband Stanley visited the home of Stanley’s brother, Adam Janus, who had suddenly collapsed and died earlier that day. The family had initially believed Adam, a 27-year-old Caucasian postal worker, had suffered a heart attack. In their grief, Stanley and Theresa unknowingly consumed Tylenol capsules from the same bottle Adam had used. Within hours, both Stanley and Theresa collapsed and were rushed to the hospital, where they were pronounced dead. Their deaths, along with Adam’s, raised immediate concerns among investigators.
Authorities soon discovered that the Tylenol capsules had been deliberately laced with cyanide. The poisonings were not isolated to the Janus family—seven people in total died from ingesting tainted Tylenol capsules purchased from various stores in the Chicago area. The case led to widespread panic, prompting urgent warnings from law enforcement and a massive recall of Tylenol products. The tragedy also resulted in significant changes in drug packaging, including the introduction of tamper-proof seals.
Despite extensive investigations, no one was ever formally charged with the murders. James Lewis, a man who attempted to extort Johnson & Johnson, the manufacturer of Tylenol, was considered a prime suspect. However, authorities lacked sufficient evidence to charge him with the actual poisonings. Lewis was convicted of extortion and served time in prison but remained a figure of speculation in the case. He was found dead in his Cambridge residence on July 9, 2023.
The deaths of Theresa Janus, her husband Stanley, and her brother-in-law Adam remain among the most haunting unsolved crimes in American history. The pain of their loss continues to be felt by their surviving family members, who still hope for justice.
