Frank Burton, 56, was found on Sept. 30 outside his Highland Park home suffering from several stab wounds. He died later in hospital.

Burton, who had a history of mental illness, was known to instigating confrontations with people in the past. Police believe that may have played a role in the attack.

The attack, which took place during rush hour, would have been be visible from the street and police are hoping someone will remember seeing it.

Investigators are asking people who commute along Centre Street North to try and remember if they saw anything suspicious the morning Barton was killed.

The stabbing happened at the side entrance of a pink and white house in the 4200 block of Centre Street.

Police were called to the home after a witness reported seeing a man being attacked. According to that witness description, the suspect is described as a stocky, darker skinned man, about 5'10".

Other witnesses are asked to call the Calgary Police Service non-emergency line at 403-266-1234 or the Homicide Unit Tip Line at 403-428-8877. Tips can also be left anonymously by contacting Crime Stoppers.
