The man, identified as dr.Mathew Betkouski, was found dead in December 1982 with no identification, cash, and a false name. Cold case detective Tim Cooper, who began investigating in 2019, matched photos and DNA to connect Betkouski to a Florida man who disappeared in 1982. Betkouski had a history of working with chemicals,discussions about cyanide,and an incident at a pharmacy suggesting he was attempting to obtain pills for experiments. The 1982 Tylenol murders resulted in seven deaths and lead to new regulations on over-the-counter medication safety.
