Gunfire
Senior Corporal Mark Nix was shot and killed while attempting to apprehend a murder suspect.
Corporal Nix and his partner had responded to backup two plainclothes officers who had spotted a car believed to have been used during a homicide two days earlier. The suspect vehicle crashed in the 4100 block of Bernal Drive following a short pursuit, and the suspect opened fire from inside the car, striking Corporal Nix in the chest, neck, and leg.
Rush-hour traffic prevented ambulances from promptly responding to the scene, so another officer transported Officer Nix to Parkland Memorial Hospital, where he succumbed to his injuries.
The killer remained in his vehicle following an exchange of gunfire with officers in which he was wounded. After an approximate two-hour standoff, members of the Dallas Police Department's SWAT team breached the car and took the man into custody. The subject was convicted of capital murder and was subsequently sentenced to death. He was executed on February 1, 2023.
Senior Corporal Nix was a United States Navy veteran of Operation Desert Storm and had served with the Dallas Police Department for just under seven years.

In tribute
I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Senior Corporal Nix gave the Dallas Police Department 7 years.
Thank you for your service to the Dallas community. Thank you for your service before it. Gone but never to be forgotten.
Rest easy, brother.
— S. Vincent Anthony, U.S. Army 1985-1993
