CHICAGO — Two Chicago women charged with killing a 19-year-old have pleaded not guilty to murder charges in the death of the victim's child.

Yovanny Jadiel Lopez died weeks after prosecutors say 49-year-old Clarisa Figueroa and her daughter, 24-year-old Desiree, cut the child from his mother's womb. They entered not-guilty pleas Monday in Cook County.

The women previously pleaded not guilty to first-degree murder charges in the death of Marlen Ochoa-Lopez.

They stand accused of luring Ochoa-Lopez to Clarisa Figueroa's home by offering to give her baby clothes, then strangling her and cutting the baby from her womb. Clarisa Figueroa then went to a hospital with the newborn, claiming the boy as her own.
