PITTSBURGH, July 20 (UPI) -- Officials say they have positively identified the body of a woman found with her uterus cut open in the apartment of a woman who had a baby that wasn't her own.

The Allegheny County medical examiner identified the dead woman as Kia Johnson, 18, of McKeesport, Pa., the Pittsburgh Tribune-Review reported Sunday.

Andrea Curry-Demus, the 38-year-old woman who showed up at a Pittsburgh hospital Wednesday, claiming to have given birth prematurely, is being held in the county jail on a charge of endangering the welfare of a child.

Other charges will be filed as the homicide investigation continues, Assistant Allegheny County Police Superintendent James Morton said.

Curry-Demus allegedly told police she bought the baby for $1,000 from a woman named Tina. She was being held on child endangerment charges.
