Family and friends gathered this evening at the wake of a Bronx teen killed two weeks ago during an NYPD drug raid. Ramarley Graham, 18, was shot Feb. 2 in his Williamsbridge apartment. Investigators have since disclosed that the officer who fired on the victim might not have been properly trained. Mourners filed into the Crawford Memorial United Methodist Church on White Plains Road to view the open casket, with Graham's father saying each day is an uphill battle. Funeral services will be held Saturday from 10 a.m. to 1 p.m. at the same church. Friends, family gather to honor slain BX teen
