Police have identified a man stabbed to death Saturday in West Philly as David McMillian, 60.

Detectives arrested Keith Beckham, 20, of 54th Street near Market for murder, possession of an instrument of crime and related offenses for the 12:45 p.m. incident on Market Street near 52nd, said Officer Leeloni Palmiero, a police spokeswoman.

An argument sparked the violence, Palmiero said. McMillian, who was stabbed in the neck and face, died at Penn Presbyterian Medical Center about 13 hours afterward. Police listed his address as the 100 block of Wynnwood Avenue but listed no hometown.
