CHICAGO (AP) — The Latest on the killing of a pregnant Chicago teenager whose baby was cut from her womb (all times local):

1:20 p.m.

A 46-year-old Chicago woman charged with killing a pregnant 19-year-old and cutting her baby from her womb told her family last October that she was pregnant, and later posted on Facebook an ultrasound and photos of a room decorated for a baby.

Prosecutor James Murphy said Friday that Clarissa Figueroa told her 24-year-old daughter that she was pregnant not long after her adult son died in 2018 of natural causes. He says the daughter, Desiree Figueroa, was surprised because her mother had previously had her fallopian tubes tied to prevent pregnancy.

Murphy says Clarissa Figueroa later told her daughter that she needed her help getting a baby. He says the mother met the victim, Marlen Ochoa-Lopez, through a Facebook page for pregnant women and lured her to her home, where the Figueroas strangled Ochoa-Lopez and cut her baby son from her womb.

12:50 p.m.

A prosecutor says a pregnant Chicago teen who was killed and whose baby was cut from her womb was strangled while being shown a photo album of the late son and brother of her attackers.

The prosecutor told Cook County Judge Susana Ortiz on Friday that 19-year-old Marlen Ochoa-Lopez managed to get her fingers under the cord around her neck and that the woman strangling her, 46-year-old Clarisa Figueroa, then yelled at her daughter, "You're not doing your f---ing job!"

The prosecutor says the daughter, 24-year-old Desiree Figueroa, then pried Ochoa-Lopez's fingers from the cord while her mother continued to strangle the teen.

Ortiz denied bond to the Figueroas, who are charged with murder, and to Clarisa Figueroa's boyfriend, 40-year-old Piotr Bobak, who is charged with concealment of a homicide.

Prosecutors say Clarisa Figueroa's adult son died last year of natural causes.
