Police have yet to publicly identify a 33-year-old Garden Grove man who went on a killing spree Wednesday, August 7 that spread from Garden Grove to Santa Ana, but Thursday they released details of his more than two-hour stabbing rampage of seemingly random victims.

The rash of violence is the deadliest seen in Orange County in several years. The four dead are all men; two  others were hospitalized –  a 54-year-old woman and 44-year-old man. None of their names have been released.
