Police are searching for witnesses after a 25-year-old man was shot to death near Trinity Bellwoods Park early Sunday morning.

Officers arrived at the west-end park just after 3 a.m. to find an empty black vehicle riddled with bullets. The discovery prompted police to search the surrounding area.

About an hour later, police found the victim on nearby Crawford Street suffering from a single gunshot wound to his chest.

"He was found in between a couple of houses in the area," said Toronto police Det. Sgt. Wayne Banks.

The man was transported to a local hospital, where he succumbed to his injuries within the hour and was pronounced dead.

Homicide investigators are working to determine what lead to the shooting.

Banks is urging anyone who knows anything about the shooting to come forward.

"The slightest bit of information could be the most important bit of information," he told reporters on Sunday.

There was a Scotiabank Nuit Blanche art installation in Trinity Bellwoods Park on Saturday night but Banks said police aren't making a connection between the shooting and the art show yet.

Police have already interviewed a number of witnesses and intend to speak to more, added Banks.

The victim's identify hasn't been released yet.

Homicide investigators are yet to reveal if there are any suspects in the case.
