GARDEN GROVE, Calif. — The man accused of stabbing four people to death in the city of Garden Grove is due in court. Police took 33-year-old Zachary Castaneda into custody Wednesday after a deadly rampage in Garden Grove and Santa Ana.
Authorities say they believe Castaneda acted alone when he robbed several businesses and attacked a half dozen people. He also reportedly has an extensive criminal history.
They are still trying to figure out the motive behind the deadly attack.
