The mother, Alice Simpson, suffered injuries to her upper back, arms and chest. She is expected to be OK. She told officers that her daughter has a history of mental illness.
Police found the teenager in Huntington Beach and arrested her for assault with a deadly weapon. She is being held on $25,000 bail.
