AURORA | An unidentified man walking on East Colfax early Saturday said he was shot by someone in a car that pulled alongside him and another person he was arguing with, police said.

A local hospital notified police that a man had come to the emergency department about about 3 a.m. suffering from a gunshot wound.

“According to the victim, he was involved in a physical altercation with someone while walking on Colfax” at about Dallas Street, Aurora police spokesperson Agent Matt Longshore said in a statement. “A few moments later, an unknown vehicle drove up next to him and an occupant fired a shot, grazing his abdomen.”

It’s unclear how the man made his way to a hospital.

“Officers have been unable to develop any suspect information at this time and we ask anyone who might have information to contact Metro Denver Crime Stoppers,” Longshore said.

Police said anyone with information can call Metro Denver Crime Stoppers at 720-913-7867. Tipsters can remain anonymous and still be eligible for a reward of up to $2,000, police said.
