Saskatoon Police are hoping to generate new leads by talking about two historical homicide cases from 1974 and 2014.

Tuesday marked the anniversary of the deaths of Dorothy Cathcart, William Graham and Frank Harder. The three (ages 47,41 and 58) were found dead inside a home in the 2700 block of 20th Street West. All three were shot and a revolver was recovered at the scene, but no arrests were ever made.

This week in 2014, 55-year-old Linda Clark died of gunshot wounds at an apartment in the 100 block of 25th Street West. Police responded to a call about gunshots and Clark was found dead outside.

Three persons of interest were identified during the investigation—but no arrests were made.
