A Casper man is accused of having sex with minors.

Twenty-One year old Andrew Nelson has entered not guilty pleas to three counts of second degree sexual assault of a minor, and two counts of third degree sexual assault of a minor.

Prosecutors say between February 2010 and last December, Nelson had inappropriate sexual contact with a number of girls that were at least fourteen years old.

One of the girls was a runaway he took into Nebraska.

Nelson and the girls eventually admitted to investigators the incidents occurred.

If convicted, Nelson could face up to twenty years in prison.

He is currently being held on fifty-thousand dollars bond, awaiting trial.
