Figueroa apparently wanted to raise another child after her adult son died of natural causes past year, authorities said.
When Ochoa-Lopez was dead, the elder Figueroa cut the teen's baby from her womb, and then called 911 and said she'd just delivered a baby that wasn't breathing, according to Murphy.
Arnulfo Ochoa, the father of Marlen Ochoa-Lopez, is surrounded by family members and supporters, as he walks into the Cook County medical examiner's office to identify his daughter's body. She was willing to buy, trade or accept a donation.
"She wanted to do great things, like all of us", added her husband, Yiovanni Lopez.
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 US, an expert said. The baby is in grave condition at a hospital. All three appeared in Cook County Court Friday and were denied release on bail.
As she left Latino Youth High School last month, 19-year-old Marlen Ochoa-Lopez had one quick errand to run before picking up her 3-year-old son from day care.
"Words really can not express how disgusting and thoroughly disturbing these allegations are", Chicago Police Superintendent Eddie Johnson said at a news conference. Once Ms Ochoa-Lopez had died, her baby was forcibly removed from her womb.
"Ultimately, DNA evidence and interviews led us to the three offenders that are now charged", Johnson said. "I know our detectives do the best they can".
The baby was taken to a hospital that day along with a woman who claimed to be the mother, according to fire department spokesman Larry Langford.
Clarisa Figueroa connected with Ochoa-Lopez on March 5 via a Facebook page for pregnant women. Desiree Figueroa told them her mother was in the hospital for problems with her legs.
In February, Clarisa Figueroa posted a picture of a crib and baby's room to a Facebook page aimed at helping improve access to baby items for families in need, Murphy said. Ochoa-Lopez's auto was found near the home.
When Ochoa-Lopez managed to get her fingers under the cord, Clarisa Figueroa yelled at her 24-year-old daughter - "You're not doing your f--ing job!" Figueroa offered new clothes for the teen's baby, and suggested that she contact her in a private message.
Julie Contreras is a spokeswoman for relatives of Marlen Ochoa-Lopez, whose body was found in a garbage can this week.
The two women have been charged with one felony count of first-degree murder and one felony count of aggravated battery of a child less than 13 years old, police said. Clarisa's boyfriend, 40-year-old Piotr Bobak, who is charged with the concealment of a homicide, was also denied bond.
She left behind a 3-year-old son, Joshua, who has reportedly been asking for his mother.
Ochoa-Lopez's family had been looking for her since her disappearance on April 23, organizing search parties and holding news conferences as they pushed police for updates in the investigation.
"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", Deenihan said.
"We lived together for four years and now I see her with her eyes closed", Yovany Lopez, standing outside the morgue in tears, told CNN affiliate WGBO. She did nothing to them.
"She didn't deserve it because she was a smart woman, a good student".
She was supposed to pick up her 3-year-old son from daycare, WGN-TV reported, but never showed up.
"She was an angel. and now she's in heaven", her mother, Raquel Uriostegui said. "This can't stay like this".
Police later found Ochoa-Lopez's body in a trash can on the property.
Subsequent DNA tests revealed that Ms Ochoa-Lopez was the baby's mother. He did and then hired a private investigator, who Cortes said helped find Ochoa-Lopez's auto near the home where her body was found. "Instead, they're mourning the loss of the mother and possibly that young child".
Figueroa and her daughter, Desiree Figueroa - who police say helped in the strangulation - were arrested this week after investigators found the teen's body in a trash can in Figueroa's yard Tuesday.
The pastor said the information was turned over to the police, but they did not enter the home and detain the residents until the forensic evidence established that Ochoa-Lopez was the mother.
