PITTSBURGH (AP) — A man has pleaded guilty to voluntary manslaughter in a drug deal and subsequent shooting that left one man dead in Pittsburgh. The Pittsburgh Post-Gazette reports Dion Jackson pleaded guilty Monday. Jackson admitted he went to buy drugs from Raheem Porter in July 2017, and Porter was killed during the sale. Prosecutors say Porter’s childhood friend Russell Page fired a bullet that inadvertently struck Porter while the three men were sitting in a car. After Porter gave Jackson five bricks of heroin, Jackson pointed a gun at Page’s head and struck his collarbone. Page tried to return fire and shot Porter’s back.
