ST. GEORGE, Utah (AP) — A Utah mother has pleaded guilty to child abuse charges after her 12-year-old son was found severely malnourished in a feces-strewn bathroom where authorities believe he was locked for about a year.

KSL-TV reports the 36-year-old woman pleaded guilty to three counts of abuse in a St. George courtroom Tuesday. She’s scheduled to be sentenced Aug. 28.

The boy weighed just 30 pounds when he was found in January in a feces-strewn bathroom with one blanket, a few empty cans of beans and a camera.

Defense lawyer Edward Flint has said the boy’s mother was overwhelmed and didn’t know what to do.

The boy’s father also faces charges after prosecutors say he failed to help the child until the boy’s weight dropped to 30 pounds.

The Associated Press is not naming either parent to avoid identifying the child.
