The latest case out of Chicago - in which 19-year-old Marlen Ochoa-Lopez was strangled and her baby cut from her womb - has similarities to numerous roughly 30 similar crimes carried out over the last three decades across the United States, an expert said.
Police said Ms Marlen Ochoa-Lopez, 19, who was lured to the home of someone she knew on April 23 with the promise of free baby supplies, was instead strangled to death, and her baby extracted from her womb.
"Words can not express how disgusting and thoroughly disturbing these allegations are", Police Superintendent Eddie Johnson told reporters at a news conference to announce the murder charges against Figueroa and her 24-year-old daughter, Desiree Figueroa.
Yavani Yadiel Lopez, the newborn baby of 19-year-old Marlen Ochoa, was in critical condition and on life support at Advocate Christ Medical Center, after her mother was strangled and Yavani was cut from her womb.
Figueroa's boyfriend, Piotr Bobak, 40, was charged with concealing a homicide.
The same day Ochoa-Lopez went missing, the Chicago Fire Department received a call about a newborn in distress at the home where her body was eventually found, authorities said.
The teenager, who was nine months pregnant, 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. The woman apparently was offering to give away extra baby clothes and a stroller that had been given to her daughter.
Her death is considered a homicide, Chicago police spokesman Anthony Guglielmi stating: "We believe that she was murdered and we believe that the baby was forcibly removed following that murder". "She was a good person".
Ms Evans and her 10-year-old daughter, Samantha, were killed in their Addison apartment and Ms Evans' 7-year-old son, Joshua, was found slain in a Maywood alley. "We won't let it go", Lopez said.
Police say that woman was Figeroa.
But Ochoa-Lopez's family said they notified authorities about her interaction with the woman much sooner. That's when the two women first connected, and when Ochoa-Lopez was allegedly lured to Figeroa's home.
The family said it has been told that DNA extracted from Ochoa-Uriostegui's toothbrush and hairbrush was used to establish a match between the teen and the baby. "She did nothing to them", Lopez told reporters in Spanish on Wednesday night. They said Ochoa-Lopez had bought items from Clarisa Figueroa before she was killed.
Ms Ochoa-Lopez's body was found at the same property on Wednesday, 15 May.
Relatives also told the paper that a few weeks ago, Ochoa-Lopez's Honda Civic was found abandoned a few blocks from the same house.
"They are finding remains of burned clothes, they are finding some blood indication on the living room carpet, some blood indication on the hallway, some blood indication on the bathroom floor", police said.
Cortes, the pastor, said Ochoa-Lopez's husband tried to immediately report her missing to the police, but was told to come back in 72 hours.
"I can't even pretend to imagine what that family is going through right now".
