Law enforcement officials in Pennsylvania have arrested two more suspects in connection with the murder of rapper Wiz Khalifa's uncle.

The Black and Yellow hitmaker's relative, 20-year-old Imani Porter, was fatally shot in the head in the parking lot of a Steak 'n Shake fast food restaurant in Pittsburgh earlier this month (Jan14).

Suspect Jaron Young, 17, turned himself in to police following the shooting and was charged with one count of criminal homicide.

On Wednesday (22Jan14), U.S. Marshalls apprehended Paul 'Los' Sanders and Michael Wolford, both 20, and charged them with homicide. They also face robbery and conspiracy charges, as well as drug violations, according to the Pittsburgh Post-Gazette.

The suspects are due in court in February (14).
