Wiz Khalifa's 20-year-old uncle, Imani Porter, was gunned down last night in Pittsburgh while sitting in a car at a local Steak ‘n Shake parking lot.

Porter was shot in the head and Allegheny County law authorities are still searching for the two suspects responsible for the slaying, while also investigating the murder's motive. Not much information is known about the heartbreaking tragedy, but police reports confirm heroin was found in the victim's car leading them to assume illegal activities were taking place prior to shots being fired. An official statement from police officer Lt. Andrew Schurman reads: “One of the things we look for is motive, and the drugs being present lends itself to some type of illegal activity prior to the shooting.”
