The officer approached the man to ask him a few questions, but he first attacked him with his fists and then opened fire.

Surveillance footage shows Dayton police officer Thaddeus Holloway using a Taser on the suspect, identified as Antoine Lowe.

Then the black man pulls out a gun and shoots the officer. The bullet pierces his temporal artery.

"Please hurry," Holloway says in the video. "I was shot in the left side of my head. I can barely hear."
