Four months after Moises Mora was gunned down outside a house in Feltonville, police are still scouring the city for a man involved in his slaying.

Investigators issued an arrest warrant Wednesday for Kharee Muhammad, 22, of Rockland Street near 10th in Logan, police said today.

Mora, 24, was killed June 10 as he was hanging out with three friends on the front steps of a house on Caskey Street near 5th in Feltonville, police said. He was approached by three men, one of whom pulled out a handgun and threatened him.

Mora tried to escape by running inside. But the robbers chased him, shot him once in the back and then robbed his friends of money and a cellphone, police said.

In the days following the attack, police arrested Andrew Baker, 29, and Joshua Voght, also 29. Both have been charged with with murder, robbery, conspiracy and related offenses.

Investigators believe Muhammad to be the third, previously unidentified man who approached Mora that night, police said.

Muhammad is known to hang out around North Philly, specifically near 17th and Dauphin streets, as well as Susquehanna Avenue between 17th and 18th streets, police said.
