One of two pleads guilty in murder of off-duty Philly officer, Moses Walker Jr.

One of two men charged in the robbery and slaying of an off-duty Philadelphia police officer almost two years ago has pleaded guilty in the case.

Twenty-one-year-old Chancier McFarland pleaded guilty to third-degree murder and robbery Thursday in the August 2012 shooting death of 40-year-old officer Moses Walker Jr.

Prosecutors said McFarland also agreed to testify against his co-defendant, 25-year-old Rafael Jones. Jones could face the death penalty if convicted of first-degree murder when he goes on trial in December.

Authorities said Walker was in street clothes and walking to a north Philadelphia bus stop after an overnight shift when two men crossed the street and tried to rob him. Police said the 19-year veteran was able to draw his gun but was shot in the chest, stomach and arm.
