Police say a Pittsburgh-area woman paid $1,000 for a newborn baby and then claimed she gave birth to it.

Thirty-eight-year-old Andrea Curry-Demus is charged with endangering the welfare of a child.

A criminal complaint says police were called Thursday afternoon to West Penn Hospital after getting a report of a woman with a baby that wasn't hers.

Police say tests at the hospital showed Curry-Demus wasn't the mother. They say Curry-Demus told them she befriended a pregnant woman about buying the baby after she miscarried in June. Authorities say she told them she paid a woman named Tina $1,000 for the baby.

Police are trying to determine who the child's mother is.

Curry-Demus is scheduled to be arraigned in Pittsburgh early Friday. She says she has done nothing wrong.
