Roll of Honor
Incident
Police Officer Patrick Zamarripa, Senior Corporal Lorne Ahrens, Police Officer Michael Krol, Sergeant Michael Smith, of the Dallas Police Department and Police Officer Brent Thompson, of the Dallas Area Rapid Transit Police Department, were shot and killed by an active shooter during a protest in downtown Dallas.
As the protesters walked down Main Street between South Lamar Street and South Market Street, a sniper opened fire on police officers who were providing security for the event. The man shot a total of 12 officers, killing five and wounding seven.
The subject was cornered in an adjacent college building and barricaded himself inside for several hours while he spoke to negotiators, during which time he stated he specifically targeted white police officers. He was killed when the Dallas Police Department's Bomb Squad moved an explosive device to the man's location using a robot and detonated it.
Officer Zamarripa was a U.S. Navy veteran and had served with the Dallas Police Department for six years.
Survivors
He is survived by his wife, 2-year-old daughter, and stepson.

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.
Police Officer Zamarripa gave the Dallas Police Department 6 years.

Rest easy, brother.
