Authorities matched fingerprint of Timothy Joley, 71, from taxi application to evidence on truck of one of the victims

Authorities investigating a 1978 double murder in Massachusetts have arrested a suspect in Florida after matching his fingerprint from a taxi application to evidence on the truck of one of the victims.

The arrest of Timothy Joley, 71, in the shooting deaths of Mark Harnish, 20, and Theresa Marcoux, 18, not only demonstrated the power of forensic fingerprint analysis – but it brought a measure of justice to families who had shown “patience, resolve and … faith” for nearly 46 years, Hampden county, Massachusetts, district attorney Anthony Gulluni said at a news briefing on Wednesday.
