LA Mom Arrested in Killings of Her 3 Young Children

A Los Angeles mother initially described as a person of interest in the deaths of her three young children has been arrested for murder. Police say Sandra Chico's three children were pronounced dead at the scene after a family member found them unresponsive in a bedroom Monday and called for help, CBS Los Angeles reports. No cause of death has been released. The children were identified Tuesday as 4-year-old Mia Camila Rodriguez, 3-year-old Mason Mateo Rodriguez, and 1-month-old Milan Mateas Rodriguez. "She would do anything for those kids," Arturo Cerezo, the children's uncle, tells NBC Los Angeles. "That's what's so hard to understand. What happened?" Chico is being held on $2 million bond. Authorities say numerous motives are being considered, including postpartum depression. (More Los Angeles stories.)
