Beer Killer: "I Wish I Had Gotten More Of The People"

SOUTH WINDSOR, Conn. (CBS 2/WCBS 880) -- First he murdered eight co-workers in a bloody rampage and then he called 911.

On Thursday, CBS 2's Tony Aiello heard the chilling confession from the killer responsible for the massacre in Manchester.

While Omar Thornton holed himself up in the building, unwilling to give up his location, he told the operator he wanted to make sure everyone knew why he opened fire in his workplace.

"You probably want to know the reason why I shot this place up. This place is a racist place. They treat me bad over here. They treat all the black people bad over here, too. So I had to take it into my own hands, had to get my hands on the problem. I wish I could have gotten more of the people."

The operator insisted he help him surrender to police, but Thornton expressed fear for his life.

LISTEN: 911 Call from Omar Thornton

Thornton: "These cops are going to kill me."

Operator: "No they're not. We're just gonna have to get you to relax."

The operator offered an agitated Thornton a safe way out, but he refused.

Operator: "Where in the building are you Omar?"

Thornton: "I'm not gonna tell you. I'm not going to tell you that. When you find me that's when everything will be over. It's all right. I guess I got enough ammo to take care of business. Tell my people that I love 'em and I gotta go now."

Operator: "Omar, I really want you to help me stop this situation. Okay."

Thornton: "Okay."

Operator: "If you work with me we'll get this to stop. Okay?"

Then there was a hesitation on the line, followed by the operator repeating "Omar? Omar?"

It's the same story Thornton had been telling family and friends for months -- racism on the job. His union and the company said he never filed complaint and was fired for stealing beer and selling it to third parties.

The phone call lasted around four minutes and police later found Thornton's body in a corner office area of the building.
