Authorities in Pittsburgh have arrested two more suspects connected to the shooting death of Wiz Khalifa’s uncle, Imani Porter. U.S. Marshals apprehended 20-year-old Paul "Los" Sanders, Jr., and handed him over to Pittsburgh police.

In addition to Sanders, Marshals also nabbed 20-year-old Michael Wolford, the alleged trigger man who shot Porter. Another suspect, Jaron Young, is already in custody and is being charged with homicide, conspiracy and several other crimes related to the shooting.

The tragic incident happened on Jan. 8 outside of a fast food restaurant at the Waterfront. According to police, Porter was delivering several bricks of heroin to the three suspects for distribution when he was shot in the head and later died at a local hospital.

“I’m sorry for his family,” said suspect Paul Sanders to CBS Pittsburgh News as he was entering the police station.

All three men have been charged with criminal homicide along with several other charges. Sanders and Wolford will also face additional drug charges as police found crack cocaine and digital scales in their possession when they arrested them on Wednesday.

Porter’s father, Jibril Abdul-Hafith, thanked Pittsburgh police for continuing to work the case and is grateful that arrests were made in his late son's death.
