A suspect armed with "machete knives" fatally stabbed four random people and wounded two others in a Southern California stabbing spree Wednesday, police said. An unidentified 33-year-old Orange County man who police said was "full of anger" was arrested. He allegedly stabbed a woman at an insurance business, two men at the Garden Grove apartment complex where he lived and a man at a gas station. The crimes spanned a period of two hours from Garden Grove to Santa Ana, which are under 10 miles from each other
