DENVER (KDVR) — Police are investigating a shooting that sent four people to the hospital Sunday night.

The shooting was reported at 9:24 p.m. on X by the Denver Police Department, which said the shooting took place in the 1900 block of Market Street. The area is only a couple of blocks away from Coors Field and has many nightclubs, bars and other establishments.

Denver police originally said three people were transported with unknown injuries, but a police spokesperson on Monday morning said there was a fourth victim injured. Police on X Monday morning said that person self-transported to the hospital.

The police spokesperson on Monday said the four victims appeared to have suffered non-life-threatening injuries.

One man walking past the scene told FOX31’s Shaul Turner that he heard 10 gunshots and at first, thought it was a car backfiring.

The 19th and Market Street intersection was largely closed as officers worked to develop suspect information related to the shooting.
