PITTSBURGH (CNN) - The body of a woman, found at the apartment of a Pennsylvania woman who arrived at a hospital with a newborn infant this week, had been partially eviscerated, and her uterus had been cut open, an autopsy found.
A placenta was found at the scene, the Allegheny County, Pennsylvania, medical examiner said.
The body "was in a state of moderate decomposition" and the woman had been dead for about two days, Medical Examiner Karl Williams said in a written statement.
The woman's hands and feet were bound by duct tape. The cause of death remains undetermined, Williams said.
Drugs were found at the scene, and authorities are awaiting toxicology results to determine whether the woman was sedated, he said. It's unclear whether the woman was alive when the infant was taken, he added.
"The most important thing right now is to identify this individual," said James Morton, assistant superintendent of Allegheny County Police.
He said investigators are seeking dental records to help with the identification process.
The body was found Friday at an apartment in Wilkinsburg, Pennsylvania, belonging to a woman with a history of attempting to steal newborns, according to court records obtained by Pittsburgh Tribune-Review.
Andrea Curry-Demus, 38, is charged with endangering the welfare of a child, a felony, and dealing in infant children, a misdemeanor. Court records show that she was arraigned on the felony charge Friday and is next set to appear in court on Thursday. She is being held at the Allegheny County Jail, WTAE reported.
According to a criminal complaint, Curry-Demus was taken by ambulance to a local hospital Wednesday with the baby, claiming it was hers. Tests at the hospital proved that she was not the mother, and police were notified.
Curry-Demus told Grande she had suffered a miscarriage in June and "did not want her mother to get upset."
In the complaint, Detective Rich Grande said Curry-Demus told him she purchased the baby from a woman named Tina for $1,000. Morton said fingerprint testing had ruled out a woman named Tina Carter, one of two other pregnant black women who have been reported missing in the area.
On Wednesday, Curry-Demus said, Tina showed up with her newborn wrapped in a towel and left. Curry-Demus said she called medics because the baby was still "dirty from birth," the complaint said.
The baby is in good condition, a hospital spokeswoman said, and will be released to child welfare workers when he is ready.
Reporters visiting Curry-Demus' apartment earlier Friday had noticed flies and smelled an odor from the sidewalk below, WTAE said. Police Chief Ophelia Coleman said the body was not found earlier because Curry-Demus' sister led them to another apartment.
Friends and relatives said Curry-Demus had told them she was pregnant for months, even having a baby shower.
"I went to the baby shower and her wedding," Ivee Blunt said. "I had no idea something like this could happen. I'm totally shocked. And she was so nice and kind. It's just unbelievable."
But Stephanie Epps, Curry-Demus' sister-in-law, said Curry-Demus would never allow her to touch her stomach.
"Pregnant women do things like that," she said. "They're happy because they're pregnant. But she would never do none of that."
As she was led out of the Wilkinsburg Police Department, Curry-Demus told reporters, "I didn't do nothing," according to WTAE.
According to court records obtained by the Pittsburgh Tribune-Review, Curry-Demus became pregnant at 12 and miscarried four months later. She had a second miscarriage in 1990, when she was 21, the paper said.
Only a few months after the second miscarriage, Curry-Demus befriended a woman who had just given birth but later attacked her with a knife and tried to steal the baby, the paper said, citing the court records.
The woman's husband intervened, and she fled, the newspaper reported.
The next day, she went to a hospital and befriended a woman who had brought her 3-week-old daughter to the hospital to be treated for meningitis, the Tribune-Review said.
When the woman went home for the night, Curry-Demus left the hospital with the baby. It was found at her home, unharmed, the following day.
In 1991, according to the records, she pleaded guilty to various charges stemming from both incidents and was sentenced to three to 10 years in prison, the newspaper reported.
She was paroled in August 1998 and ordered to serve 10 years of probation, the paper said.
Curry-Demus was examined by psychiatrists at the Allegheny County Jail before her sentencing and was diagnosed with severe depression, personality disorders and auditory hallucinations, the newspaper reported, citing court records.
She told doctors she spent a lot of time thinking about her miscarriages and "kept hearing babies cry," the Tribune-Review said.
Wilkinsburg is just east of Pittsburgh, Pennsylvania.
Earlier this year, a Kansas woman was sentenced to death in the 2004 killing of a Missouri woman whose baby was cut from her womb.
Lisa Montgomery was convicted in October in the death of Bobbie Jo Stinnett, 23, who was found strangled in her Skidmore, Missouri, home. Stinnett's womb was cut open, and her unborn child was missing. Montgomery was found days later at home in Kansas, where she was attempting to pass the baby off as her own.

PITTSBURGH (KDKA) - A woman is facing criminal charges after police say she lied about giving birth and allegedly bought an infant.
Andrea Curry-Demus, 38, allegedly told police she purchased a newborn baby boy from a woman.
The bizarre story began when paramedics took Demus to West Penn Hospital from a home in Wilkinsburg.
She claimed to have just given birth to the baby. The umbilical cord was still attached. The doctors were suspicious and tests showed she was not the mother.
Police were called and in paperwork officers claimed Demus admitted to them to buying the baby from a woman she only knew as "Tina" for $1,000.
KDKA has learned that Demus made news 18 years ago when she was accused of abducting a baby from Children's Hospital.
That same year, when she was known only as Curry, was also charged with stabbing a woman in an alleged plot to steal a newborn baby from a home in Wilkinsburg.
Demus told police she had a miscarriage in June and didn't want her mother to get upset about it. That's why she started talking to this woman named "Tina" about getting the baby.
Demus claims the woman dropped off the newborn yesterday wrapped in a towel.
