A Casper man accused of sex crimes against minors, will receive a mental evaluation to determine if he's fit to stand trial.

Forest Price has pleaded not guilty by reason of mental illness, to three counts of first degree sexual abuse of a minor, and five counts of third degree sexual abuse of a minor.

Investigators with the Casper Police Department say Price and the victim first met in Glenrock, and Price was the victim's father's roommate.

The victim told police that the sex acts started in June 2013 and lasted through June 2015.

When interviewed, Price denied the sexual encounters and at first agreed to take a polygraph, but later cancelled that appointment, and refused to speak further with investigators, unless his attorney was present.

Price is being held on $60,000 bond and is waiting his mental evaluation and trial.

He could receive between 25-to-50 years on charge of first degree sexual abuse of a minor charge, and up to 20 years in prison on each third degree sexual abuse of a minor charge if convicted.
