Police are seeking the public's help in locating a stolen car believed linked to a fatal shooting in the Annex, while the victim's father wants the shooter to turn himself in.

"If they are man enough to come forward and go to the police and say something why they did that, but I don't think they're man enough," Enrique Herrara told CTV Toronto on Wednesday about whoever killed his 23-year-old son Sebastian.

The young man had been out with his girlfriend in the Annex at the Brunswick House bar, a popular hangout for students.

At 1 a.m. Saturday, police were called to a shooting.

Det. Stacy Gallant told a Wednesday news conference that Herrera and his girlfriend returned to their car for a cigarette. They were parked in a laneway south of Bloor Street between Major Street and Brunswick Avenue.

As they were returning, a gunman confronted them. He got out of the passenger side of a vehicle, robbed Herrara of a crucifix necklace and then shot him in the stomach as the victim lay on the ground.

"It was for nothing. It was a standard steel necklace," Enrique said

Paramedics took Herrara to hospital, but he died there of his injuries, becoming Toronto's 31st homicide victim of 2008.

Gallant said the car used in the homicide may have been stolen on Friday.

"We're asking for the public's help in locating this stolen vehicle," he said. "With the potential of more than two million people out there who have eyes, more than us, we need them to search the areas, search the underground garages, the parking lots, the back alleyways -- anywhere where that car may be."

The car in question is a 2001 four-door Toyota Corolla sedan, either silver or grey in colour. Its Ontario licence plate is ARRN 777.

The suspect is described as black, 6 feet to 6'2" with shoulder-length, cornrow-style hair. He is estimated to be 25 years old with a large nose. A white male, also thought to be 25, drove the car.

Potential witnesses ares asked to contact police at 416−808−7400, Crime Stoppers anonymously at 416−222−TIPS (8477), online at www.222tips.com, or text TOR and a message to CRIMES (274637).
