Idaho cold-case identification yields possible suspect in 1982 Tylenol murders

Idaho investigators have named Dr. Mathew Francis Betkouski, found dead from cyanide in a Boise church in December 1982, as a possible suspect in the Chicago-area killings of seven people with cyanide-laced Tylenol that year. No one was ever charged. Chicago police say detectives are in contact with Idaho authorities. The case remains open.
