A Gumshoe's Justice: The Unlikely Role of Forensic Science in Solving Cold Cases The Everett Police Department's use of an undercover gum sales pitch to collect DNA from a suspect may seem like a scene straight out of a crime comedy, but the outcome is anything but humorous.
Mitchell Gaff, 68, has been sentenced to 50 years in prison for the decades old murders of Susan Vesey and Judith Weaver.
Gaff's DNA had already been entered into the national Combined DNA System Index after he was convicted of raping two teenage sisters in 1984. This made him a potential match for evidence from Weaver's murder.
