A Casper man has admitted that he brutally beat his girlfriend.

Thirty five year old Russell Wright has pleaded guilty to one count of aggravated assault and one count of strangulation of a household member..

Investigators with the Casper Police Department say in late April, officers responded to a residence in the 100 block of North Washington Street.

Detectives observed the bedroom had blood spatter all over the walls and floors of the bedroom.

There were broken items scattered on the floor, items tipped over, broken photo frame, bloodied scissors, hammers and a broken white broom stick on the floor with blood on it.

Other officers went to the Wyoming Medical Center where they interviewed Wright's girlfriend who had bruises, abrasions, and a cervical collar on her neck.

She told officers she and Wright had been drinking and she had been been doing laundry, when a verbal argument with Wright escalated to physical violence.

She tried to leave, they pushed each other, and she was hit in the ankle and fell.

Wright began hitting her with what she thought was a metal rod.

Wright hit her with a hammer then she blacked out.

When the victim came to, Wright put a knee on her chest, held her down by the throat with one hand and swung a hammer with the other hand.

She found a pair of scissors and stabbed Wright in the hand.

The victim was able to walk to a friend's house where her friend called 911.

Wright initially claimed self-defense and told police the victim wouldn't quit yelling at him.

As part of a plea deal, prosecutors will seek no more than a two-and-one-half to five year prison sentence.

Wright is being held without bond and will be sentenced at a later date.
