Homicide investigators are looking for clues in a car where a man's dead body was found slumped over the steering wheel on Sunday morning.

Police say the man appears to have been shot in the chest, adding it could have happened as early as 7 p.m. Saturday night. He was pronounced dead in the silver sedan.

Investigators haven't identified the victim, except to say he is a well-dressed man.

However, a man at the scene told CP24 he believes the victim is his cousin, suggesting a positive identification by police could be coming soon.

The car was parked on Hammell Street near Alexis Boulevard, in the Bathurst Street and Sheppard Avenue area. The body was found by a woman who was walking her dog Sunday morning at about 8 a.m.

"I saw the car sitting there with the door open," she says. "I looked in the passenger window but I didn't see anything because they were tinted.  Then I walked back and looked in the door and I saw a body."

One witness says she noticed one of the car's doors was open on Saturday evening, but said she was too scared to investigate further.

Residents of the neighbourhood say they didn't hear any signs of a struggle or gunshots last night.

"Nobody heard anything," says Bryan, who lives nearby. "I've been talking to people. That's the strange thing, nobody heard a thing. It's a shock to everyone around here."

There are reports a gun was found on the car's passenger seat and a black balaclava was discovered on the road.

Toronto Police Det. Wayne Fowler wouldn't confirm those details Sunday morning, saying it is too early to release such information.

"We're at the preliminary stages of the investigation," he says "We've yet to determine who this person it, if it is the person who actually operates the car. We don't know.

"At this point in time we don't know... when this actually took place. That is going to be the focus of our investigation."

Fowler did say that the incident was "definitely not a suicide," saying police are treating it as a murder. It is the city's 61st homicide this year.

Police are transporting the car, with the body inside, to a forensic lab where they will do further testing.
