A man who admitted setting a pair of fires -- inside San Juan High School, in Southeastern Utah -- will spend up to 15 years in prison.
Deven White, 19, has been sentenced this week, on arson and burglary charges.
He was also ordered to pay $1-million in restitution.
Blanding police say White, and a 23 year old accomplice, broke into the school twice, to start fires.
Christopher Stolzer has been found incompetent to stand trial, and is at the Utah State Hospital.
