What on earth would possess someone to do something as horrible as this?

I’ve written about similar cases to this one before.

Woman charged in grisly crime

PITTSBURGH, Pennsylvania (CNN) — A Pennsylvania woman has been charged in the slaying of an 18-year-old woman who was found with her uterus cut open and her fetus removed, authorities said Sunday.

Andrea Curry-Demus, 38, of Wilkinsburg was charged Sunday with criminal homicide kidnapping and unlawful restraint in connection with last week’s death of Kia Johnson, Allegheny County police Superintendent Charles Moffatt said.

Police found Johnson’s body in Curry-Demus’ apartment Friday, two days after Curry-Demus arrived at a hospital with a newborn and falsely claimed that the baby was hers, authorities said. Police have not confirmed whether the infant belonged to Johnson, whose family reported her missing last week.

Johnson’s eviscerated body — which police said they found after receiving calls about a foul odor coming from the apartment — “was in a state of moderate decomposition,” and she had been dead about two days, Medical Examiner Karl Williams said. The cause of death hasn’t been determined, he said.
