The man suspected of gunning down four police officers in a suburban coffee shop was shot and killed by a lone patrolman investigating a stolen car early Tuesday. Four people were arrested for allegedly helping the suspect elude authorities during a massive two-day manhunt.

Maurice Clemmons was carrying a handgun he took from one of the dead officers when a Seattle policeman recognized him near a stolen car in a working-class south Seattle neighborhood about 2:45 a.m., Assistant Police Chief Jim Pugel said.
