It has been 50 years since the triple homicide of three Saskatoon individuals, and police are sending out a renewed request for public assistance in finding their killer.

Forty-seven-year-old Dorothy Cathcart, 41year-old William Graham, and 58-year-old Frank Harder were all found dead at a home in the 2700 block of 20th Street West.

Police say they observed that the back door to the residence had been forced open, and the thermostat was set to high. Both a revolver and casing were recovered from the scene.

The investigation remains open. Anyone with information is asked to contact the Saskatoon Police Service or Crime Stoppers.
