DENVER — Three people were critically injured in a shooting near 15th Street and Market Street in Lower Downtown Denver early Sunday morning, the Denver Police Department said.

Police said three people — two men and one woman — were taken to a hospital.

Two of the victims have injuries that are not life threatening, police said.

Market Street was closed between 15th and 16th streets, but it reopened about 1:20 p.m.

Witnesses say they heard dozens of shots just after 2:30 a.m.

“All of a sudden, we heard probably 30 shots or so break out,” says Pierce McKenna, the bar manager at Oskar Blues, which is less than a block away from where the shooting happened.

“We looked down Market Street and saw everybody running and screaming.

“We walked toward 16th just to see if we could help somebody, and as soon as we got here we saw a woman who was shot through her stomach, and she was just kind of walking toward this parking lot with her boyfriend holding her.”

Within minutes, he said officers had the area covered.

“It was just kind of mayhem, honestly, people running and screaming,” McKenna said. “I’ve lived in Denver for 3 1/2 years, and I’ve never seen anything like this.

Police did not release information regarding a possible suspect.

The investigation into the shooting is ongoing. Anyone with information is asked to call police at 720-913-2000 or Metro Denver Crime Stoppers at 720-913-7867.
