PUEBLO, Colo. -

The man shot and killed by police Tuesday, may not have fired at an officer, as originally thought, police said.

Police responded to a domestic violence call shortly after 11 a.m. Tuesday. When they arrived, the suspect menaced the officer with a gun. Police first thought he shot at the officer, but now they think that wasn't the case.

"There was confusion because they thought the male suspect fired at him. But it might've been the door slamming," said Sgt. Eric Gonzales, with the Pueblo Police Department. "Because he slammed the door, and he might've heard the door slamming, and some people might've thought that was a gunshot."

After menacing the officer, police said the suspect took off running. Officers caught up with him near an apartment complex between Evans and Abriendo Ave. Gonzales said when he pointed a gun at one officer, another officer shot and killed him.

Neighbors told KRDO NEWSCHANNEL13 on Tuesday, they heard eight to nine gunshots. But police said they can't confirm how many shots were fired.

"It was in front of a brick apartment complex, right in front of a patio, things are going to echo, and there's cars around," Gonzales said. "It can also be echos they're hearing."

The Critical Incident Team is investigating the incident. Gonzales said they are reviewing tapes of officer radio chatter, they confiscated the weapons, and they are waiting for snow to melt to find shell casings. Investigators will also interview officers involved and neighbors.
