A Mills man pleaded not guilty to one count of first-degree sexual assault during his arraignment in Natrona County District Court on Wednesday.

John Kosmata was arrested last month after his girlfriend reported to police the alleged rape coupled with abusive and controlling behavior.

On Sunday, Feb. 7, Kosmata had returned to his residence intoxicated and beat the victim. He ordered her to undress and go to the bedroom, where he then used a number of sexual toys on her, causing her to bleed, according to the affidavit filed with Natrona County Circuit Court.

Kosmata also stabbed her with a fork, and then cut off a small piece of her hair.

The victim said the abuse continued into Monday, and Kosmata also told her to drink a glass of wine. During the assault, the victim's eye was bruised, and Kosmata told her to call in sick to work for two days.

On Wednesday, she was allowed to go to work, but was instructed that if anyone asked about her injuries, to say she fell in the bathtub and hit her head.

A co-worker asked the victim about the eye, and she later admitted what had happened and went to the hospital.

The victim then contacted law enforcement, and told officers she was in an abusive relationship.

Police interviewed Kosmata, who admitted to the various sexual acts and cutting the victim's hair.

When asked if he could have gone too far in his behavior, he said that if he hurt the victim and was in a police station, then yes, he went too far.

Kosmata is being held on $50,000 bond awaiting trial. If convicted, he could face between five and 50 years in prison if convicted.

At the time of this incident, he was out on bond for an unrelated aggravated assault case.

That case began in late November when he allegedly beat a man.

His bond had been set at $50,000, and was reduced to $25,000 in December before he bonded out.
