WILKINSBURG, Pa. (AP) — A body with its hands bound was found Friday at the apartment of a woman who showed up at a hospital with a newborn she falsely claimed was her child but later said she had obtained for $1,000, authorities said.

The body was found in the home of 38-year-old Andrea Curry-Demus, police said. Authorities would not say whether it was male or female.

Wilkinsburg Police Chief Ophelia Coleman said the body was found lying face down. She said she didn't know how long it had been there. Investigators said police checked on Curry-Demus' apartment after reporters called authorities about a foul odor coming from inside.

Earlier Friday, police said they were concerned that the infant's real mother — described as a thin, black female in her 20s or 30s named Tina — might be in danger, or need medical attention.

The mystery started when Curry-Demus showed up at West Penn Hospital in Pittsburgh on Thursday with a newborn baby that still had its umbilical cord attached, police said. Tests later proved she was not the mother — despite her claims to the contrary, police said.

Curry-Demus pleaded guilty in 1991 to aggravated assault after stabbing a Wilkinsburg woman in an alleged plot to steal the woman's infant. Curry-Demus, then known as Andrea Curry, was sentenced to 10 years' probation.
