A 26-year-old man was killed by a speeding car while crossing West Alameda Avenue at Morrison Road, west of downtown, on Sunday night, the Denver police reported.

The accident happened just before 9 p.m. A vehicle suspected of involvement left the scene, but a 17-year-old suspect was later arrested for investigation of vehicular homicide and leaving the scene of an accident, according to police.

The Medical Examiner identified the victim as Nicholas Richling.

The driver then called family members, but not emergency responders, according to police. The suspect was arrested away from the scene.

The suspect was driving an orange Dodge Caliber. Witnesses told police that the Dodge and an unidentified black sedan were revving their engines at a traffic light, and then took off at “highway speeds.”

They travelled about 1,400 feet before one struck the pedestrian, according to police. Police are seeking any surveillance footage that may have captured the race.
