The 'womb raider' accused of strangling a pregnant teenager to death distracted her with a photo album of her dead son then ambushed her with an electrical cable and then used a butcher's knife to cut her baby out from her womb, it was claimed on Friday as fresh, sickening details of the murder emerged.

Clarisa Figueroa, 46, her daughter Desiree, 24, and her boyfriend Piotr Bobak, 40, were all denied bond on Friday during their first court appearance in Chicago.

Cameras were not allowed inside the courtroom for the hearing. They will return before a judge on June 3.

After their appearance, prosecutors shared the bond proffer they presented to convince a judge not to grant them bail.

It contained harrowing details about the killing including the fact that it was the second time victim Marlen Ochoa-Uriostegui, 19, had been to the home and the fact that Clarisa told her daughter in October last year that she was pregnant despite having had her Fallopian tubes tied.

Clarisa Figueroa, 46, and her daughter Desiree Figueroa, 24, ambushed Marlen Ochoa-Uriostegui, 19, on April 23 while she looked at a photo album in their home. Both were denied bond on Friday

The revelations on Friday included that;

Clarisa claimed she was pregnant in October 2018 to her daughter Desiree

On April 1, Marlen went to their home to get baby clothes and Clarisa wanted to kill her that day

She escaped with her life because Clarisa's daughter's boyfriend was there

After presenting her with a photo album on April 23, the next visit, Clarisa climbed on top of Marlen and strangled her with an electrical cable

It went on for four to five minutes until the pregnant teenager died

Clarisa used a butcher's knife to slice her stomach from side to side

She retrieved the baby, placenta and umbilical chord and put them in a bucket

At hospital, she was checked and doctors found no evidence she had given birth

It remains unclear if anyone called police to report how suspicious she was

Blood was found on the living room carpet of the home and the bathroom

Police found her boyfriend bleaching and hosing a rug on Wednesday

Desiree, who is four months pregnant, has made a full confession to the plot

A month before the murder, Claris also told her adult daughter - who made a full confession on Thursday - that she 'needed help killing a pregnant woman and taking a baby.'

Social media posts reveal that she had been obsessed with babies since last year and was telling friends she was pregnant with a baby she planned to call Xander.

Marlen's first visit to their home was on April 1 when she went to pick up free baby clothes Clarisa offered her on a Facebook group for women in need where the teenage other had made appeals for strollers and baby clothes she couldn't afford.

During that visit, Clarisa told her daughter that she wanted to kill her and steal her baby. The only reason Marlen escaped with her life that day was that Desiree's boyfriend, who was also there, refused to help them.

Clarisa passed off her murderous intentions as an 'April Fool's joke.' On April 23, Marlen returned to the house for more goods and the boyfriend was not there.

While she was in the living room, Desiree - who is four months pregnant herself - and her mother turned up the music inside the home, according to the proffer.

They then gave her a photo album of Clarisa's dead adult son. Police previously said his name was Xavier and that he had died aged 26.

Marlen Ochoa-Uriostegui had gone to the house first on April 1 after meeting Clarisa on Facebook. During that visit, the 46-year-old allegedy wanted to kill her but was stopped by her daughter's boyfriend. On April 23, the second time she went to the home, she fought for her life by putting her fingers between her neck and an electrical cable as she was strangled but was outnumbered. Clarisa then used a butcher's knife to cut her son out from her womb. He remains in neonatal intensive care with zero brain activity

In their proffer, prosecutors said he was in fact 20, called Xander, and that he had died only last year.

Desiree 'distracted' Marlen with a photo album of him while her mother crept behind her on the couch with an electrical cable, according to prosecutors.

She then ambushed her, wrapping the cable around her neck, but the 19-year-old was able to slip her fingers in between her neck and the cable.

As she struggled to get it away from her neck, Clarisa yelled out to Desiree, who was watching: 'You're not doing your f****** job!'

Clarisa's boyfriend Piotr Bobak, 40, tried to help them cover up the murder by washing the house of blood. When police arrived at the home on May 14, he was hosing and bleaching a rug in the backyard

At that, Desiree 'stepped up' and started 'peeling' Marlen's fingers away from her neck.

Clarisa then climbed on top of her and continued to strangle her for 'four to five minutes', until she urinated.

It was then that she realised she had died, she told her daughter, because she'd read that 'a person will urinate on themselves when they die.'

Once she was dead, Desiree brought her mother a butcher's knife, blanket and bucket.

Clarisa then cut the pregnant teen's belly open 'from side to side' and retrieved the baby, the placenta and the umbilical cord.

She placed him in a bucket with the placenta and left the umbilical cord sticking out, the proffer states. Clarisa then wrapped her in a blanket and 'lugged' her to an outdoor trash can with the cable still tied around her neck.

Social media screen grabs show she began posting about a baby as early as February 5

On March 5, more than a month before she went to the house, Marlen and Clarisa spoke on the group, with Clarisa offering her baby clothes

Figueroa also posted this in the mother's group in March. After one woman responded 'right here', she replied: 'I don't feel lonely anymore yay'

In March, on her Facebook page, Clarisa Figueroa posted a photo of the nursery in her home. It showed that a mural of a tree had been painted to surround 'Xander'

That is when she called 911, claiming to have just given birth and saying the baby was not breathing. She was covered in blood when paramedics arrived but it was the victim's.

Once at the Christ Hospital, she was cleaned of the victim's blood by an OB Technician.

Though she showed 'no signs consistent with a woman who had just given birth', she was not arrested.

The hospital declined to comment on the case when asked by DailyMail.com if it alerted authorities on April 23.

'Our top priority is to provide the safest and highest quality care for the patients and communities we serve.

'Out of respect for patient privacy and in compliance with federal and state regulations, we are unable to provide comment.

'We have been cooperating with authorities and as this is an ongoing police matter, we’re referring all inquiries to local law enforcement,' a spokesman said.

Instead, over the next three weeks, they cleaned the home with the help of Clarisa's boyfriend Bobak and set up a GoFundMe account claiming the baby was hers and asking for money.

This is the home where the young mother's body was found and where the baby was born three weeks ago. Paramedics went to the house on April 23 after Clarisa called 911 saying she had just given birth but they never went inside. Instead, she brought the baby out

Police were seen inspecting a fire pit in the woman's backyard on Wednesday night (pictured). Her body was found in a trash can

They were arrested on Wednesday after police received a tip about the Facebook interaction Marlen had been having with her from one of her friends.

The young mother had been missing for three weeks and her distraught husband was frantically looking for her, allegedly with little help from the police.

When authorities went to the home for the first time on May 7, they encountered Desiree who told them that her mother had just given birth.

They then located the victim's car a block away - Desiree had put it there - and ordered a DNA test of the baby who was and is still in a neonatal intensive care unit with zero brain activity.

That is when they discovered the plot and arrested all three suspects.

Once in custody, Desiree made a full confession. It is unclear if Bobak or Clarisa have confessed.

Marlen's body was found in a trash can in the back yard with the cable still around her neck.

The suspects created a GoFundMe campaign to raise money for the baby's medical expenses. Police say Clarisa Figueroa called 911 claiming she had just given birth at home

'These defendants were not that wise. The body's in a garbage can on the premises with the murder weapon,' one official said on Wednesday.

Police are also now looking into whether they tried to lure any other expectant mothers to the home.

According to neighbors, all three lived in the basement of the house which belongs to Clarisa's parents, Jose, 70, and Angelita, 60.

Marlen's family is distraught.

'[They are] in complete agony mourning the loss of the child,' translator Julie Contreras told DailyMail.com shortly after the arrests. Contreras added that Ochoa-Uriostegui 'suffered a horrific death at the hands of monsters.'

'The family wants justice for Marlen,' she said.
