The man was discovered on December 4, 1982, inside Sacred Heart Catholic Church with no identification but an envelope containing $1,900 in $100 bills and a typed note signed 'Wm. L. Toomey.' According to UPI, he had dyed hair, finely filed nails, unseasonably tanned skin, and either brand new or recently pressed pants.
Ada County Detective Tim Cooper reopened the case in 2019 and identified Betkouski through a key found on his person that led detectives to Jacksonville, Florida. A DNA sample from the man showed a 'very high probability' that he shared the same father as the decedent's only living relative.
Betkouski had worked at two drugstores during his undergraduate studies and had a history of volatility, including a documented fascination with cyanide and explosives. According to CBS News, colleagues became concerned about him after he discussed 'the perfect crime' and how 'cyanide could be used as a less messy means of taking one's life.' He was fired from his job at Lockheed in March 1982 after creating an unspecified disturbance at a pharmacy.
Police found pictures of Betkouski in Chicago, but they believe these were likely taken in December 1981. According to Daily Mail, authorities tracked down his family and visited his childhood home, where they uncovered a small bottle of cyanide that was 'likely homemade' and a map of Chicago.
The Ada County Sheriff's Office has shared its findings with the Chicago Police Department and is calling on members of the public with information about Betkouski to contact them. The developments are to be the subject of an Unsolved Mysteries documentary titled Unmasking the Tylenol Killer, which is set to air on Roku in October.
