A woman and her daughter pleaded not guilty Wednesday to charges alleging they strangled pregnant 19-year-old Marlen Ochoa-Lopez and cut her baby from her womb.

Clarisa Figueroa and her daughter, Desiree, each face more than two dozen counts of first-degree murder, aggravated kidnapping, dismembering a human body and concealing a homicidal death.

Piotr Bobak, identified by prosecutors as the elder Figueroa’s boyfriend, joined both women in pleading not guilty in a courtroom packed with Ochoa-Lopez’s family and supporters. Bobak allegedly helped clean the scene after the killing.

Moments after the brief hearing, Ochoa-Lopez’s family stood in the lobby of the Leighton Criminal Court Building carrying poster-size copies of the defendants’ mugshots with “GUILTY” emblazoned on their foreheads.

“If there’s no justice for this family, there will be no peace,” activist and family spokeswoman Julie Contreras told reporters.

With the case drawing intense public interest, Desiree Figueroa’s attorney asked Wednesday that a “gag order” be instituted. Such orders usually prohibit attorneys or anyone associated with the case from speaking publicly about the matter, in an effort to limit pretrial publicity.

The case was assigned Wednesday to Judge Peggy Chiampas, a former Cook County prosecutor who took the bench in 2007.

But in her absence, Judge Sophia Atcherson handled Wednesday’s arraignment. She left the gag order for Chiampas to rule on later.

The Figueroas’ indictment includes charges of aggravated battery alleging they injured Ochoa-Lopez’s baby.

Those charges will likely be upgraded to murder to reflect that the boy, Yovanny Jadiel Lopez, died June 14, seven weeks after he was cut from his mother’s womb. His death was ruled a homicide by the Cook County medical examiner’s office.
