A Casper man is accused of brutally beating his girlfriend.

Thirty five year old Russell Wright has pleaded not guilty to one count of aggravated assault with a deadly weapon, one count of felonious restraint, one count of strangulation of a household member, and one count of domestic battery, second offense.

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 is claiming self-defense and told police the victim wouldn't quit yelling at him.

He fell asleep, woke up, tried to fix breakfast and she then tried to stab him with a pair of scissors.

Wright is being held without bond awaiting trial and he could face up to 10 years in prison on the aggravated assault charge, five years in prison on the felonious restraint and strangulation charge, and one year in jail on the domestic battery charge if convicted.
