A gunman on a shooting rampage in southern California killed three people on Tuesday in an attack at a home and three carjackings, before killing himself with a shotgun as officers closed in, police said.

The rolling spate of violence, which included at least one execution-style killing, spanned several miles across a number of communities in suburban Orange County, southeast of Los Angeles, including the cities of Tustin and Santa Ana.

The violence occurred just a week after a massive manhunt for a fugitive former Los Angeles policeman wanted in a series of shootings targeting officers and their families ended in a fiery stand-off in the mountains above Los Angeles.
