REDDING, Calif. -

A man who claims to have heard to the officer-involved shooting in Redding Saturday night said he heard the whole thing.

The incident began shortly before 5:30 p.m. Saturday when officers were called to a house at 1250 Liberty Street in downtown Redding.

Inside the home, 28-year-old Daniel Copeland is said to have been acting suicidal and fired a shotgun in an attempt "to build up courage to shoot himself," according to a preliminary investigation by the Shasta County Sheriff's Office.

The Sheriff's Office said multiple Redding police officers arrived on the scene to confront Copeland.

Steve Kirk, who lives at an apartment complex across the street, said he heard it all.

"I heard the cops say, 'We're not trying to hurt you. Put the gun down.' And all of a sudden I heard a big old commotion with the shotgun being cocked, and all of a sudden the dude starts shooting the shotgun off."

That story lines up with one released by the Shasta County Sheriff's Office, who has taken over the investigation of the shooting according to critical incident protocol.

Copeland was taken to the hospital, treated and released into custody. He was booked on charges of assault on a peace officer, negligent discharge of a firearm and brandishing a firearm at a peace officer.

Kirk claims he heard at least 15 rounds being shot off.

That information has not been confirmed by authorities.

On Sunday, the home on Liberty Street was riddled with bullets.

Outside, Copeland's mother told KRCR that her son has mental health issues. She also claims the shotgun he was holding wasn't loaded when police fired on him.

As for the officers involved in the shooting, six have been put on paid administrative leave until the investigation is concluded.
