A Golden Police Department officer was killed and a second was seriously injured after he was struck by a suspected drunken driver in a crash on Colorado 58 Wednesday evening.

The two officers, a man and a woman, were investigating a crash near Washington Avenue and were outside their vehicle when they were struck just before 5 p.m., Golden Police Chief Joe Harvey said late Wednesday night.

The section of highway is a curved overpass and another officer was stationed nearby, Colorado State Patrol officials said in a news release.

Both officers were forced under the vehicle and trapped in the previous accident, CSP officials said.

One officer, a 33-year-old man, died at the scene of the accident. The second officer, a woman, was taken to hospital with serious injuries.

The driver was arrested at the scene on “suspicion of impaired driving,” state police officials said late Wednesday. The agency did not release the driver’s name.

Harvey declined to reveal the officer’s name Wednesday night, citing his family’s wishes, but held back tears as he described the man as an “amazing human being” who served in the military and flew Black Hawk helicopters.

Colorado 58 is closed in both directions and there is no expected reopening date.
