ST. GEORGE, Utah — A southern Utah woman whose malnourished son was found in a feces-strewn bathroom is appealing her sentence of up to 45 years on child abuse charges.

Court records show the 36-year-old mother has filed a notice of appeal in the case. Her lawyer has said she was overwhelmed and unable to care for the boy as she dealt with addiction to heroin and methamphetamine.

The Associated Press is not naming the woman or to avoid identifying the boy.

Police believe the 12-year-old boy had been locked away for at least a year.

He weighed 30 pounds when he was found with one blanket and a few empty cans of beans in the filthy bathroom with camera surveillance in the city of Toquerville.

The woman pleaded guilty to three felony charges of intentional child abuse.
