Mother arrested in the deaths of her 3 young children in East L.A.

A mother has been arrested in the killings of her three young children, who were found not breathing in an East Los Angeles home, officials announced Tuesday.

Sandra Chico, 28, was arrested on suspicion of murder on Monday.

Sandra Chico, 28, is seen with her daughter Mia in an undated photo provided by family members.

The arrest came after a family member at a home in the 600 block of Ferris Avenue called authorities about two children who were possibly not breathing. Deputies arrived to find three unresponsive children in a bedroom around 12:45 p.m. Monday, according to the Los Angeles County Sheriff’s Department.

The children, two boys and one girl, were pronounced dead at the scene.

There were no signs of trauma to the children and it remains unclear how they died.

The L.A. County coroner’s office later identified the children as 4-year-old Mia Camila Rodriguez, 3-year-old Mason Mateo Rodriguez and 1-month-old Milan Mateas Rodriguez.

Milan Mateas Rodriguez, Mason Mateo Rodriguez and Mia Camila Rodriguez are seen in undated photos posted to GoFundMe.

The young mother is being held on $2 million bail, according to county inmate records. She is scheduled to appear in court on Wednesday.

Officials have not provided information on a possible motive for the killings.

“We still don’t know the cause, or the motive. All I know is, she wasn’t right,” the children’s grandmother, Rosalba Flores Castillo, said in Spanish.

Sheriff’s Lt. Chuck Calderaro said Monday there was no indication of prior calls for service or suspected abuse at the home.

No further details were immediately available.

The family has set up a GoFundMe page to cover the children’s funeral expenses, and loved ones planned to gather at the home for a private prayer vigil Tuesday night.

Anyone with information is asked to contact the Sheriff’s Department’s Homicide Bureau at 323-890-5500.
