A 17-year-old who was wanted in connection with an armed robbery and murder of a North Philadelphia store clerk May 26 surrendered to police Thursday after his accomplice was arrested by U.S. Marshals.

Police identified Marvell Hargrove on Monday as a suspect in the robbery and shooting at the Trax Food Store on the corner of Girard Avenue and Front Street.

Surveillance video inside the store and near its entrance on Front Street showed that accomplice Quasheam Richburg, 20, was armed with a shotgun during the incident.

Hargrove can be seen trying to grab the cash register and running from the scene with Richburg after police say he shot and killed the 50-year-old store clerk.

Acting on a tip, U.S. Marshals arrested Richburg at his home in South Philadelphia on Norwood near McKean at about 8:30 a.m. Thursday.

Police said Hargrove surrendered at about 3 p.m., and officials were anticipating announcing which charges the teen will face.
