A 30-year-old mother was arrested Tuesday after authorities found her naked and holding a knife next to her three young daughters who had been stabbed to death in their home in an unincorporated area of Torrance.

Deputies arrived at the 1000 block of West 223rd Street after they received a rescue call around 5:10 p.m. Family members at the scene told the deputies that "a mother had killed her children," according to a statement from the L.A. County Sheriff's Dept.

Authorities told KTLA that they found the three girls, ages 3, 2 and 2 months old, in a pool of blood in bed with their mother, Carol Coronado. They were pronounced dead at the scene.

"There was a lot of blood," Lt. Dave Coleman told the L.A. Times. "It was a pretty substantial scene inside the residence."

Investigators found several knives at the home and are investigating if there were more causes to the children's deaths.

Neighbors said the children's grandmother visited Coronado's home and discovered the grisly scene after she received a call from her daughter earlier that day saying she was going crazy. The father was at home at the time but was working outside, fixing his car.

Coronado was arrested and taken to the local hospital for examination and then to Carson Sheriff’s Station where she was booked on suspicion of murder.
