A Natrona County man is denying he sexually assaulted a teenager.

James Rogers has pleaded not guilty to charges of first and second degree sexual assault of a minor, and two counts of third degree sexual abuse of a minor.

According to Evansville Police, the victim told investigators that Rogers was watching her in April, when he took her into a bedroom and had sex with her.

The victim's mother and stepfather were at work at the time, and had asked Rogers to look after the victim and her younger brother.

Prosecutors say they have DNA evidence to back up their case.

Rogers is being held on 35-thousand dollars bond and could receive up to 50 years in prison if convicted.
