Memorial to 5 officers killed in Dallas police ambush to be unveiled

Officials are set to unveil a sculpture honoring five police officers killed in an attack in downtown Dallas three years ago.

Sunday marks three years since Micah Johnson opened fire on a peaceful protest. The Army veteran killed four Dallas police officers and one transit officer. Authorities killed Johnson using a robot-delivered bomb. July 7, 2016, is considered the deadliest day for U.S. law enforcement since the Sept. 11, 2001, terror attacks.

A sculpture honoring Dallas officers Lorne Ahrens, Michael Krol, Michael Smith, and Patrick Zamarripa, and Dallas Area Rapid Transit Officer Brent Thompson will be unveiled Monday in front of police headquarters.

Dallas Police Association President Mike Mata spoke about the numbness police felt that night, realizing what was happening, as well as the support the department felt the following days.

“I think what it did show — out of a tragedy like that -- it showed the citizens of Dallas truly do care about the men and women, not just the police department, but the fire department. First responders, in general,” he said. “How the city came to our defense, to our support. It was amazing.”
