The Edmonton Police Service has released a photo of an SUV and surveillance video of two suspects in last week's fatal shootings of a gang member and his 11-year-old son, who were gunned down while parked outside a fast-food restaurant.

Staff Sgt. Rob Bilawey with the EPS Homicide Section says in a news release that they hope sharing the images might help someone

recall seeing the black BMW SUV or the suspects before or after Thursday's shooting.

Police have identified the father as 41-year old Harpreet Uppal and say he was a high-level gang member involved in the drug trade, but they have not identified the boy.

Police say they were told the suspects arrived in a black BMW SUV, exited their vehicle, ran towards Uppal's white SUV, fired a weapon and fled the scene.

They've said that another boy who was with Uppal's son and was around the same age was also in the car but escaped without physical injuries.

Police have been investigating a possible link between the shooting and a burned 2012 BMW X6 found on a road nearby, but said in Sunday's news release that they're still working to determine if it's the same vehicle from the crime scene.
