Rolando Alberto Tirado, 37, was killed in the early hours of May 1, 2011, while working an off-duty security detail in a parking lot on South 35th Avenue in Phoenix. A U.S. Marine Corps veteran and a Buckeye Police Department officer for seven years, Tirado served as a School Resource Officer and a negotiator on the SWAT Team; his law enforcement career totaled eleven years.

At about 1:15 a.m. Tirado and a partner stopped a truck with dark tinted windows after it was seen driving erratically. As Tirado spoke with the driver, a male passenger exited, walked around the back of the vehicle and shot Tirado from behind. Tirado died at the scene. A gunfight then broke out; the gunman was shot and killed, Tirado’s partner suffered multiple gunshot wounds and was taken to a hospital in critical condition, and the driver of the SUV was critically wounded. A third person fled and was arrested by the Phoenix Police Department two days later.
