Attacker Kills 4 in Series of Stabbings in California Cities Associated Press GARDEN GROVE, CALIFORNIA - Investigators believe a man who stabbed four people to death and wounded two others targeted his victims at random during a bloody rampage across two Southern California cities, authorities said. The 33-year-old man from the city of Garden Grove was "full of anger" when he carried out violent attacks and robberies at businesses and killed two men at his own apartment complex during the two-hour wave of violence Wednesday, police said. He was arrested as he walked out of a convenience store in the neighboring city Santa Ana, dropping a knife and a gun he had taken from a security guard he had just killed. Authorities planned to release his name Thursday afternoon. The violence appeared to be random and the only known motives seem to be "robbery, hate, homicide," Garden Grove police Lt. Carl Whitney told reporters. "We know this guy was full of anger and he harmed a lot of people tonight," Whitney said Wednesday. .
