A Canada-wide warrant has been issued for a suspect in a stabbing death in downtown Calgary last month.
Police said the victim, who was identified by police as Russell David Younker, 49, was stabbed on April 15 during a fight on 11th Street S.W. near the Downtown West-Kerby CTrain station.
Younker collapsed at the scene while the attacker ran away. Younker later died in hospital.
Police believe the victim and the accused knew each other, and the altercation resulted from a previous incident that occurred between them.
Christopher Douglas Mathers, 34, was identified as a suspect because of a tip provided by a member of the public, police said Tuesday.
Upon attempting to locate Mathers, investigators said they learned he had moved out of his house and had potentially left Calgary.
Mathers is believed to have connections to British Columbia, Halifax and London, Ont.
A warrant has now been issued for Mathers. He faces a second-degree murder charge.
Police describe him as six-foot-one, about 220 pounds and having brown hair and blue eyes.
Investigators are still hoping to speak with a potential witness.
The witness was seen wearing a blue hoodie with a red logo on the front, a baseball cap, sunglasses and a backpack.
Anyone with information on the whereabouts of Mathers is asked to call the homicide tip line at 403-428-8877, or the Calgary Police Service non-emergency line at 403-266-1234.
