AURORA, Colo. (KDVR) — Colorado State Patrol said a 44-year-old man killed in a crash involving an Aurora Police officer did not yield to oncoming traffic when the crash happened.

According to CSP, the crash happened around 8:20 p.m. at the intersection of E. Bates Avenue and S. Chambers Road.

The 44-year-old man was driving a Toyota Corolla, and the officer was driving a marked police vehicle.

The police vehicle hit the passenger side of the Corolla and rolled after the crash.

The identity of the 44-year-old will be released by the Arapahoe County Coroner’s Office. The identity of the officer was not yet available.
