Detective uses chewing gum sting to solve 1984 cold case murder

A detective from Everett, Washington, linked two cold case killings to a known predator by devising an undercover sting involving chewing gum, CBS News reported.

Detective Susan Logothetti, who investigates cold cases at the Everett Police Department, focused on a 1984 murder of Judy Weaver, a bar and cafe manager, according to CBS News.

Judy Weaver was known for her generosity and toughness with patrons, and her daughters described her relationship with her boyfriend Bill Richards, who was abusive, as reported by CBS News.

On the evening of June 1, 1984, Judy and Bill were celebrating the sale of the Bel-Nes Cafe with friends, during which Judy became intoxicated, CBS News detailed.

Detective Logothetti's innovative gum sting helped obtain fresh DNA evidence necessary to charge the suspect, showing how cold cases can be solved decades later, according to CBS News.

The story was also covered by CBS News' "48 Hours" correspondent Peter Van Sant, highlighting the detective's clever approach to catching the elusive killer.
