Toronto police are probing a shooting at a backyard birthday party BBQ that left two men dead and a woman in hospital in serious condition.
They say they're not getting a lot of co-operation from witnesses.
Officers were called to a home in the city's east end at 1 a-m Sunday, where they arrived to find many of the 200 people attending the party running from the scene.
Investigators are asking anyone with backyard surveillance video in the neighbourhood to submit it to police.
