William Chrisman, 33, was shot and killed on September 27, 2017, while working as a part-time security guard outside Flash Dancers strip club in Jacksonville. Chrisman, a two-tour Iraq veteran and father of four, had picked up an extra shift when he attempted to break up a fight between two customers and was shot in the parking lot.

Family remembered him as a protective, kind-hearted man who stood up for those more vulnerable; his father-in-law, Mike Ellis Cooper, said Chrisman lost his life trying to stop the situation from escalating. The Jacksonville Sheriff’s Office opened an immediate investigation and released surveillance images showing two people believed to have information about the shooting. The shooter remains at large.

Does anyone who was in that area that night or who recognizes the people in the surveillance images have information to share with investigators?
