ARVADA, Colo. (KDVR) — The Jefferson County District Attorney announced Monday that the officer who shot and killed Johnny Hurley will not be charged.

Hurley was killed by police on June 21 after he had killed a gunman targeting officers in the Olde Town part of Arvada.

The attacker had shot and killed Officer Gordon Beesley, who responded to Olde Town for a report of a suspicious person. Hurley, who was inside a nearby Army Navy Surplus store, heard the gunshots and went outside where he shot and killed the gunman.

When officers arrived on the scene, they saw Hurley with a gun standing over a body and assumed he was involved.

“Based on the facts, this officer had reasonable ground to believe Hurley was a second mass shooter,” District Attorney Alexis King said.

In a statement released through Hurley’s attorney, his mother encouraged people to see this as an opportunity for change.

“I imagine that many people are angry and that is understandable. I would ask that instead of acting out on your anger, that you use that energy to be the change you wish to see in the world. Engage in meaningful conversations that might make a difference in how we all may move forward together,” Kathleen Boleyn said.

After details of Hurley’s actions were released with the initial police investigation, Arvada Police Chief Link Slate called Hurley “a true hero” and said he “likely disrupted what could have been a larger loss of life.”

The officer who shot Hurley has been on paid leave since the shooting. He has not decided if he will return to work, but a department spokesperson said reintegration counseling will be offered if he does decide to return.

Bill Troyanos works at the surplus store where Hurley had been. He said Monday he heard the gunfire that day in June.

“I still sit in the Square and think about that day,” Troyanos said.

“I feel bad for the police officer that shot him (Johnny Hurley). I mean, that’s horrible. He’s got to live with that for the rest of his life,” Troyanos said. “I don’t blame him, given the circumstances at the time.”
