Not guilty by reason of insanity is a plea that didn’t sway the judge in a bench trial for California’s 32-year-old Carol Ann Coronado.

The mother of three was convicted of three counts of first-degree murder in the stabbing deaths of her three daughters, 2-year-old Sophia, 16-month-old Yazmine and 2-month-old Xenia, and sentenced to life in prison without parole.

She’d been found covered in blood on a bed next to her dead children inside their home on May 20, 2014.

She’d injured herself with self-inflicted stab wounds after carrying out the grisly incident.

Her defense attorney maintains she was suffering from postpartum psychosis.

Her neighbor, 27-year-old Ashley Madrid, even told the LA Times back in 2014, “She had a zoned-out look” as she was led away in handcuffs.


Her husband, Rudy Coronado, who found the horrific crime scene, said he thought he saw “a demon” inside his wife when he discovered what he did.

Her lawyer had asked for leniency and asked the judge to send her to a mental hospital instead of jail.

The judge declined, saying that any treatment would have to be in prison.

The motive for the murder is still unknown, but prosecutors say she may have wanted revenge on her husband, who’d told her he was considering a divorce.

They also believe that a messy bathroom accident by one of the girls may have caused Coronado to “snap”.

Her obstetrician, however, testified that she showed no signs of depression after the birth of her third daughter.

Her lawyer plans to appeal.
