33-year-old gang member Zachary Castaneda has been taken into custody in the stabbing spree that has left 4 random people dead and 2 injured in Orange County
Police say Castaneda robbed more than half a dozen businesses and stabbed 6 random citizens during a two-hour wave of violence.
He was arrested as he came out of a 7-Eleven in Santa Ana, dropping a knife along with a handgun that he had taken from a security guard he just killed.
The video below posted on Facebook by the Garden Grove Police Department Thursday shows Castaneda unleashed his fury on an innocent woman at an insurance office. She fought back and survived.
