Englewood police are seeking witnesses who were in the area of where a chef at a popular Denver restaurant was gunned down on Saturday night.

Sgt. Chad Read said Tuesday that members of the public who were near the 3000 block of South Acoma Street between 7:30 p.m. and 9:30 p.m. on Saturday are asked to contact investigators.

Police have released few details in the killing of 33-year-old Nicholas Lewis, a chef at the popular Denver restaurant Blackbird Public House and a single father to a young boy. Read declined to say if Lewis lived in the area where he was killed or if he was targeted.

“We are following up on several leads right now and because it’s an ongoing investigation there’s a not a lot of information we can put out at this time,” Read said.

Brian Midtbo, Blackbird’s owner, told The Denver Post on Monday that Lewis was a devoted father of an 8-year-old.

“He’s one of the nicest people I’ve ever met in my life,” Midtbo said. “He worked all night and got up every morning and took his kid to school. Nick was a great guy and a great dad. Nick actually never had anybody that didn’t love him.”

Midtbo said Lewis’ death remains a shocking mystery.

Englewood police say they found Lewis while responding about 8:30 p.m. on Saturday to a report of shots fired on the 3000 block of South Acoma Street. Investigators said he was “on the ground with several gunshot wounds,” according to a police news release on Sunday.

Lewis was taken to a hospital where he later died.

Anyone with information on the shooting is asked to call Metro Denver Crime Stoppers at 720-913-7867. Tipsters can remain anonymous and are eligible for a reward up to $2,000.
