PHILADELPHIA, AUG. 16 -- A man sought by police since the remains of six people were found in his apartment and bones of a seventh on his roof was charged with murder today after his mother persuaded him to surrender, authorities said.

Harrison (Marty) Graham, the subject of a weeklong manhunt, was charged with seven counts of murder and seven counts of abuse of a corpse, said police Lt. Dennis Logan. The murder charges came several hours after police began questioning Graham about the remains authorities found Aug. 9 amid a jumble of trash in his apartment.

Graham, 29, accompanied by his mother, Lillian Graham, surrendered to police about 1 p.m. on a street corner about 10 blocks from his apartment, said Capt. Robert Grasso.

Graham had called his mother Sunday morning and asked her for food and cigarettes, according to Detective Gerald Whartenby, a police spokesman. After meeting her son, she persuaded him to surrender and then called police, Whartenby said. Graham was last seen a week ago when his landlord's son asked him to move from the noisome apartment, a reputed drug haven. Shortly afterward, the six bodies were unearthed from a piles of mattresses trash, and a warrant was issued for Graham's arrest.
