Murder charges have been filed against a woman and her daughter in the death of a pregnant Chicago woman whose baby was cut from her womb.

Police say 46-year-old Clarisa Figueroa and her daughter, 24-year-old Desiree Figueroa were charged Thursday with first-degree murder in the death of 19-year-old Marlen Ochoa-Lopez. The older woman’s boyfriend, 40-year-old Piotr Bobak, is charged with concealment of a homicide.

Police say the break in the case came after detectives learned more than a week after Ochoa-Lopez’s April 23 disappearance that she had responded to a Facebook offer of free clothes and arranged to pick them up.

The newborn was in grave condition and not expected to survive, police spokesman Anthony Guglielmi said.

Ochoa-Lopez was found dead early Wednesday behind the house, more than three weeks after she disappeared. The nine-months-pregnant woman was last seen leaving her high school on April 23, the same day paramedics were called to the home several miles away on the Southwest Side about a newborn with problems breathing.

"We believe that she was murdered, and we believe that the baby was forcibly removed following that murder," Guglielmi said, calling it an "unspeakable act of violence."

Chicago Fire Department spokesman Larry Merritt said a 46-year-old woman called 911 reporting that her newborn baby was in distress. When paramedics arrived "the baby wasn't breathing, the baby was blue," said Merritt. Paramedics tried to resuscitate the baby on the way to the hospital, he said.

The family of Ochoa-Lopez, a married mother of a 3-year-old son, said a woman on Facebook had lured her to the home by offering a stroller and baby clothes.

"She was giving clothes away, supposedly under the pretense that her daughters had been given clothes and they had all these extra boy clothes," said Cecelia Garcia, a spokeswoman for the family.
