A South Bay mother was back in court after being convicted of first degree murder for the death of her three daughters.

Carol Ann Coronado, 32, may face life in prison without the possibility of parole if she is found to be sane. Today, the sanity phase of the trial was scheduled to begin. If Coronado was determined to have been insane during the time of the killings she could be sent to a state mental hospital.

Last year, sheriff’s deputies responded to a rescue call at a home near Carson where they met family members who told them that Coronado had killed her three daughters.

Prosecutors declined to seek the death penalty.
