A Sunset man who pleaded guilty to aggravated sexual abuse of a child has been ordered to undergo treatment at the Utah State Hospital, then serve a minimum term of 9 years of a 5-years-to-life term at the Utah State Prison.

Michael D. Thornock, 39, 1009 N. 250 West, was found competent to stand trial in 2nd District Court on the two first-degree felony charges after an evaluation at the state hospital.In a plea negotiation, Thornock pleaded guilty to one charge, which carries a minimum mandatory sentence of 3, 6, or 9 years, in return for having the second charge dropped.

Judge Rodney S. Page this week said the evaluation and Adult Probation and Parole pre-sentence report determined Thornock is a danger to all female children and that he would not voluntarily undergo treatment on his own.

He ordered Thornock into the state hospital for treatment. Then, when the staff determines Thornock is either cured or treatment has progressed as far as it can go, he must to serve the remainder of his sentence in prison.

Thornock was charged with the two felonies in incidents involving an 8-year-old girl that occurred in Sunset between July and August in 1987 and during the 1985-86 school year, according to court records.
