The officer’s partner opened fire on the man stabbing the officer, officials say. The man was pronounced dead at the scene.

A ping from a cellphone tower Wednesday morning led Trenton police to a 37-year-old armed murder suspect who was fatally shot during an interaction with officers, police officials said.

The incident, which was captured on several different security cameras in the area, unfolded at around 8 p.m. Nov. 21.
