A 17-year-old boy is dead after a stabbing on Main Street Thursday night.

Officers were called to the 800 block of Main Street shortly after 6 p.m. and found the male victim who appeared to have been stabbed in the upper body, said police.

Officers have identified the victim as Jessie Jules Pierre McKenzie.

He was waiting at a bus stop with a 16-year-old male friend Thursday night when the incident happened.

Police say the investigation has revealed the victim and his friend encountered a man and a woman involved in a dispute.

The male suspect went after McKenzie in an unprovoked attack and allegedly stabbed him, said police.

Both the man and woman took off. The victim's friend also left but has since been located by officers.

When a bus arrived at the stop where McKenzie had been stabbed, the bus driver saw the injured teen and called 911. McKenzie was rushed to hospital but later died, said police.

CTV News has learned McKenzie was wearing an ankle monitoring bracelet and was a Level 4 car thief but investigators don't believe that played a role in the homicide.

The male suspect in the alleged stabbing is described as aboriginal in appearance, in his twenties to early thirties, five feet 10 inches to five feet 11 inches (177 - 180 cm) in height, with medium build, wearing dark clothing and in possession of a knife.

The woman is described as aboriginal in appearance, five feet five inches in height to five feet eight inches (167 cm - 176 cm) in height, with long dark hair in a ponytail and a medium build, wearing a light coloured jacket.

Officers are looking to speak to a witness who left the scene before police arrived and may have important information about the incident.

The witness is described as a white male, forty to sixty-years-old, five feet five inches to five feet six inches (167 - 170 cm) in height, with short grey or white hair, heavy build, wearing large glasses, an old dark blue baseball cap and a dark bomber-style jacket.

Anyone with information on the incident is asked to contact investigators at 986-6508, or Crime Stoppers at 786-8477.
