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 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. After an approximate two hour stand-off, Dallas SWAT breached the car and took the killer into custody. He was also taken to Parkland Memorial Hospital for treatment of gunshot wounds. The suspect was charged with capital murder and was subsequently sentenced to death.

Senior Corporal Nix had been a member of the Dallas Police Department for just under 7 years. He was a United State Navy veteran of Operation Desert Storm. He is survived by his fiancee, parents, and sister.

Mark, you were my academy classmate and partner and I will never forget you my friend. I was sitting here just thinking about the times we were DT partners at the police academy and when we worked CBD as young officers. I even remember some conversations we had about women back in the day....:). Good memories. I can't believe it's been almost 10 years since you left us. We will keep your mom and family in our prayers. We still holding it down in Dallas.
