Twenty-nine Arizona Highway Patrol/Department of Public Safety officers gave their lives in the line of duty. These brave heroes and their families are in the hearts and minds of all who worked with them, of those who follow in their footsteps and of the public whom they served.

Of the 29 deaths, eight were the result of murder, 17 were traffic related, two died in a helicopter crash, one died in a helicopter accident, and one killed when a train exploded.
