A Maryland woman accused of killing two of her adopted daughters and keeping their bodies in a freezer for months has pleaded guilty to first-degree child abuse involving a third girl.

Renee Bowman, 44, entered the plea Friday in Calvert County Circuit Court and could receive up to 25 years in prison.

The charge involves a girl adopted by Bowman who was found wandering in her neighborhood after jumping from a window in September 2008.

The child, then 7, had a bloodstained nightshirt and sores and lesions over much of her body. Authorities say they subsequently searched Bowman's house and found the frozen remains.

Bowman faces separate first-degree murder charges in the deaths of the other two girls. That trial is set to start Nov. 9.
