Elisabeth “Betty” Broderick, the jilted ex-wife of prominent San Diego attorney Daniel T. Broderick III who turned to murder to settle festering scores with her longtime husband and his new bride before spending decades in custody for her crimes, has died at a hospital after being transferred from a state prison in San Bernardino. She was 78.

The first wife of the high-profile lawyer who specialized in winning medical malpractice cases was serving a 32-year-to-life prison sentence for the 1989 killing of her former husband and his wife, Linda.

Broderick’s death was announced by the San Bernardino County Sheriff-Coroner’s Office hours after she died Friday. County officials said Broderick died at the Chino Valley Medical Center. The cause of death was not disclosed.

Rhett Broderick, the youngest of the couple’s four children, said he and two of his siblings were able to travel to Chino and spent time with their mother before she died.
