Prosecutors announced Friday they will not seek the death penalty against a South Bay woman charged with stabbing her three young daughters to death last year.

The decision was revealed in Compton Superior Court, where the trial for Carol Coronado was scheduled for Nov. 19. Coronado, 31, must return to court on Oct. 13, District Attorney’s Office spokeswoman Sarah Ardalani said.

Coronado is charged with killing her daughters — Xenia, 3 months; Yazmine, 16 months; and Sophia, 2 — on May 20, 2014, at their home on 223rd Street near Meyler Lane in the unincorporated county area near Carson.

Their bodies were found neatly arranged from youngest to oldest on her bed, court testimony revealed.

A county grand jury of 24 people indicted Coronado a year ago on three counts of capital murder with the special circumstance allegation that she committed multiple murders. Prosecutors could have sought the death penalty, but the maximum sentence she could now receive is life in prison with no chance of release.

Coronado also is accused of attempting to kill her mother, Julie Piercey, who walked into the grisly scene and grabbed the knife away from her daughter.

The killings occurred while Coronado’s husband, Rudy, was outside working on his truck.

Defense attorneys have indicated they believe Coronado suffered from postpartum depression following Xenia’s birth. She remains in custody without bail.

The District Attorney’s Office did not provide a reason for the decision not to seek the death penalty.
