Senior Corporal Lorne Bradley Ahrens, 48, was one of five Dallas Police Department officers killed on the night of July 7, 2016. Ahrens, born May 9, 1968, in Los Angeles, had served with Dallas for 14 years after 11 years with the Los Angeles County Sheriff’s Office. He was working security at a downtown protest when a sniper opened fire, killing five officers and wounding seven others.

Ahrens was shot, taken to hospital, underwent surgery, and died of his injuries. The shooter, identified as Micah Johnson, targeted white police officers; after a standoff in a college building he was killed when a Bomb Squad-delivered explosive device was detonated. No other suspects were identified in Ahrens’ death.

Ahrens is survived by his wife, Katrina, a Dallas Police detective, and their two children. His colleagues and community paid tribute to his service and sacrifice. If anyone knew Lorne Ahrens or has information about that night, please share what you remember.
