A man has been charged with second-degree murder in connection with the killing of 59-year-old Robert Gladue. Gladue was found injured in a home near 95 Street and 106 Avenue on Thursday by officers responding to an assault call, police said. He was taken to hospital with life-threatening injuries. Police said 42-year-old Dustin Chisholm, who was found nearby, was initially charged with aggravated assault. The charge was upgraded to second-degree murder after Gladue died in hospital from blunt force trauma injuries on Sunday. Police said the two men knew each other.
