PHILADELPHIA (AP) – Authorities say it had been a violent night in Philadelphia even before the early morning shooting death of an off-duty police officer.

Late Friday night, a 47-year-old man was shot in the head in North Philadelphia and pronounced dead just before midnight at Einstein Medical Center.

At about 3:40 a.m. Saturday in Southwest Philadelphia, a 23-year-old man was shot in the back and was pronounced dead minutes later at the scene.

A double stabbing shortly before 2:30 a.m. Saturday in North Philadelphia sent a 24-year-old man and a 48-year-old man to the University of Pennsylvania hospital in critical condition.

Minutes earlier, another man in his 20s was critically injured in a shooting in West Philadelphia takeout restaurant.

Shortly before 12:30 a.m. Saturday, a 24-year-old man was stabbed in the face on a city bus in Southwest Philadelphia. He was reported in stable condition.
