The case involving a Natrona County man accused of committing murder, is moving forward.

A judge has ruled that prosecutors have met their burden of probable cause, against 67-year old Charlie Mapp, who has been charged with second degree murder.

His case is now being bound over to district court.

Investigators with the Casper Police Department say earlier this month, 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 earlier in the evening, 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.

Mapp is being held on $150,000 bond awaiting trial, and could face between 20 years to life in prison, if convicted.
