(AP) — A Kansas City woman has pleaded guilty to abusing her 10-year-old daughter who was found in a locked closet in 2012.

The woman entered the plea Tuesday to felony child abuse, child endangerment and assault charges. The Associated Press is not naming her to protect the child’s identity. The woman will be sentenced April 25 and prosecutors have agreed to seek a prison sentence of no more than 20 years.

The girl weighed just 32 pounds when she was found in a urine-soaked closet. She told authorities that she hadn’t been allowed to eat for days and hadn’t attended school since kindergarten.

The woman told a judge Monday she was pleading guilty because she believes the state’s case is strong enough to convict her.
