A Pennsylvania teenager has been arrested and charged over the shooting death of rapper Wiz Khalifa's uncle last week (ends10Jan14). The Black and Yellow hitmaker's relative, 20-year-old Imani Porter, was shot in the head in the parking lot of a Steak 'n Shake fast food restaurant in Pittsburgh last Wednesday (08Jan14) and he died from his injuries on Thursday (09Jan14). Suspect Jaron Young, 17, turned himself in to police on Thursday and he has since been slapped with a count of criminal homicide. Allegheny County detectives believe Porter and two associates had been planning to sell heroin to Young and a second suspect, who is still at large, when he was killed. Khalifa paid tribute to Porter via his Twitter.com blog on Thursday, writing, "Rest in peace Imani. Your (sic) with Allah now... My uncle was younger and more level headed than all of us. I would have never seen this happening in a million years... God has a plan. Rest with God Imani."
