The custodial mother of a 2-year-old boy found dead two years ago at a northern Arizona campground has been sentenced to 17 years in prison.

Christina Priem of Flagstaff, Ariz., pleaded guilty in May to two counts of child abuse in an agreement with prosecutors. She was sentenced Monday (June 4), KPHO-TV, Phoenix, reported.

The skeletal remains of Sylar Newton were found in a wash in August 2010, weeks after he was reported missing from the campsite near Rimrock. Authorities said witnesses told them the boy appeared to be under the influence of drugs or medication. No one was charged with his death.

Priem had faced more than 32 years in prison. Her 17-year sentence will be followed by supervised probation.

Priem’s mother, Nancy Collins, was also sentenced Monday in the case, receiving supervised probation. Collins had pleaded guilty to one count of child abuse.
