Three people, including a mother and daughter, have been charged in the death of a young pregnant woman on Chicago's Southwest Side.

Wednesday, the Cook County Medical Examiner's Office said remains found at a home in the 4100-block of West 77th Place in Chicago's Scottsdale neighborhood were identified as those of Ochoa-Lopez. She was reported missing three weeks ago from Pilsen and was nine-months pregnant when she disappeared.

Officials said her cause of death was ligature strangulation. Her death has been ruled a homicide.

The baby allegedly taken from Ochoa-Lopez's womb remains in grave condition at Christ Hospital.

Ochoa-Lopez had previously been identified as Marlen Ochoa-Uriostegui. Uriostegui is her mother's name. Both police and the Cook County Medical Examiner identified her as Marlen Ochoa-Lopez.

The loss of 19-year-old Marlen Ochoa-Lopez has left her family in shock as her baby continues to fight for his life.

Articles of Ochoa-Lopez's clothing and blood were found inside the home, CPD officials said at a press conference Thursday.

Her loved-ones have been left heartbroken and horrified.

"Why did these people, why did these bad people do this? She did nothing to them," said Yovani Lopez, her husband. "She was a good person."

Ochoa-Lopez's family was seen entering the medical examiner's office late Thursday morning to see her body. In addition to the newborn baby, Marlen also leaves behind a 3-year-old child.

"It's so hurtful, so hurtful to see the person, your wife, who you lived with for four years and now you see her with her eyes closed," he said.

The family said they believe the pregnant teen was lured to the home through a Facebook post promising free baby items.

"It just seems surreal, like you see this stuff on movies," said family spokesperson Cecilia Garcia.

Police were seen investigating outside a home on Chicago's Southwest Side where a missing pregnant teen's remains were found.

On the day Ochoa-Lopez vanished, the fire department went to the home after a woman said she'd given birth.

"The caller gave birth 10 minutes ago," a 911 dispatcher tells the Chicago Fire Department. "Forty-six years of age. The baby isn't breathing. The baby is pale and blue. They are doing CPR."

Marlen Ochoa-Uriostegui, 19, was last seen last Tuesday after leaving Latino Youth High School in Pilsen.

That baby is now fighting for his life at Christ Hospital in Oak Lawn.

"The detectives went to see the baby, get the DNA testing, and confirm that that is Marlen's baby," Garcia said.

A person who didn't want to be identified said that the woman from the home, one of three people being questioned, used to babysit her infant, until she began acting strangely.

"She told me how she was getting really attached to the baby, how she couldn't wait to be a mom again," the woman said.

Police have yet to name the three persons of interest and what charges they could be facing.

As for the baby fighting for his life, Ochoa-Lopez's family said he has been named Yovani Yadiel Ochoa-Lopez.

About a half a block away from the house where Ochoa-Lopez's remains were found, a memorial of flowers, candles and stuffed animals is growing.

"I can't fathom what could be in your mind to hurt such an innocent young person that's trying to do good for her family," said Cristy Hall.

Hall came by to drop off a bear and paper flowers her son had made.

"It makes me -- as a mother -- want to just bring my kids closer. Like it makes you not want to let your children out of your sight," she said.

Ochoa-Lopez's aunt said they are hoping to set up a GoFundMe campaign to help with expenses soon, but warned that the campaigns currently listed on GoFundMe for the family are not by or associated with them, and warned the public not to donate.
