Toronto police say they're searching for a sniper who killed a man on a residential driveway last fall using a high-powered rifle.
Clinton Yow Foo, 37, died from a single shot in the city's east end in October last year.
Police say the gun used in the killing was found near the crime scene.
Det.-Sgt. Tam Bui says the shooter killed Foo in the dark, on a windy night, while the target was moving.
He says Foo was known to have connections to organized crime in the Greater Toronto Area, while the shooter might have a connection to Quebec.
Bui says police are also looking to speak with a friend who found Foo on the driveway, and a person he was talking to on an international phone call when he was shot.
Since his death, they discovered that Foo might have travelled to St. John's in July last year when his family believed he was out of the country.
"The circumstances leading up to this are a little bit unusual," said Bui. "The evidence we've recovered, the planning, this, we believe, is unique."
