A Colorado man has been arrested and charged with two counts of first degree sexual assault against a woman at Alcova Lake.

According to documents filed in Natrona County Circuit Court, sheriff's deputies arrested Levi Nathanael Keller on Wednesday evening.

Keller made his initial appearance in circuit court on Thursday and bond was set at $150,000.

Keller and two friends drove from Colorado on Monday to stay at a cabin owned by one of the friends.

The victim and her friends drove from Colorado on Tuesday.

Keller and the victim were watching TV. He is accused of plying the victim with a combination of alcoholic beverages and energy drinks. The affidavit says she had never been intoxicated before and never had sex before.

The victim passed out and woke up repeatedly and asked Keller to stop assaulting her.

She later was able to get away and was picked up by two men driving along Wyoming Highway 220 who dropped her off at Sloan's General Store.

These two good samaritans were later located by the sheriff's office.
