The Chicago cyanide slayings began on Sept. 29, 1982. Adam Janus, a 27-year-old postal worker, died in a Chicago-area hospital of what was first thought to be a heart attack. When his family gathered in his home to mourn that evening, brother Stephen Janus, 25, and his wife, Theresa, 19, unknowingly took cyanide-laced pills to ease their stress. Both died within the next two days. Mary Kellerman, a 12-year-old, also died that day from taking a poisoned Tylenol tablet.
