Pittsburgh ? A woman suspected of cutting open a pregnant woman’s uterus and stealing the baby has been charged with homicide, unlawful restraint and kidnapping, police said Sunday.

Andrea Curry-Demus, 38, of Wilkinsburg, Pa., is charged in the death of Kia Johnson, 18, of McKeesport, Pa. Curry-Demus is accused of taking the baby boy to a Pittsburgh hospital and claiming it was her own.

Johnson’s body was found Friday in Curry-Demus’ apartment. The body was positively identified through dental records, Allegheny County Medical Examiner Karl Williams said Sunday.

In the criminal complaint, police said that video surveillance at the Allegheny County Jail from Tuesday afternoon shows Curry-Demus talking with Johnson for several minutes. The women were at the jail visiting different inmates, police said.

The clothing Johnson is seen wearing on the surveillance tape was consistent with the garments found on her body, police said.

Allegheny County Police Superintendent Charles Moffatt said the jail was the last place Johnson was seen alive.

Curry-Demus was being held in county jail on Sunday and it was not immediately clear whether she had an attorney. A lawyer who had represented her previously did not immediately return a phone message left Sunday.
