PHILADELPHIA (AP) — A city police officer pursuing an armed suspect Tuesday afternoon was fatally shot, the fourth Philadelphia officer to die in the line of duty in the last year, authorities said. Another officer was wounded and the suspect was killed.

The officer who died, Patrick McDonald, 30, was shot in the chest, Mayor Michael Nutter said. The other officer, 35-year-old Richard Bowes, was shot in the leg. He was in stable condition and expected to be OK, Nutter said.

"We are in pain, and we are very angry about what's going on here in our city," Nutter said.
