A Natrona County man accused of killing another man in an argument, is admitting to a lesser charge.

Sixty-eight year old Charlie Mapp, has pleaded guilty to one charge of voluntary manslaughter.

Investigators with the Casper Police Department say in August 2014, officers were called to the 400 block of North Washington Street, for a report of a shooting.

When they arrived they found Richard Abeyta, suffering from a single gunshot wound to the head.

He was transported to Wyoming Medical Center, where he later died of injuries that he sustained.

Witnesses told investigators that there was a small gathering of people at a residence, and alcohol was involved.

Mapp had gone to get more drinks, and when he returned, Abeyta then started an argument, accusing Mapp of making advances on his girlfriend.

A short time later, Mapp went to his vehicle, retrieved a .38 revolver and shot Abeyta.

When interviewed, Mapp told officers that during the argument, Abeyta's language became abusive and threatening.

He also claimed that he was about six-to-eight feet away from Abeyta at the time of the shooting, and he had pointed the gun at the ground, and not at Abeyta's head, but police could not find any evidence, that the bullet hit the ground, or ricocheted off of anything.

As part of a plea deal, prosecutors will seek no more than an eight year prison sentence.

Mapp is being held on $150,000 bond and will be sentenced at a later date.
