SEATTLE — The man suspected of gunning down four police officers in a suburban coffee shop was shot and killed this morning by a lone patrolman investigating a stolen car.

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 south Seattle neighborhood about 2:45 a.m., Assistant Police Chief Jim Pugel said.

The officer saw something moving, got out of his car, saw Clemmons and ordered him to show his hands and stop.

"He wouldn't stop," Pugel said. "The officer fired several rounds."

Clemmons also had a serious gunshot wound from one of the four officers killed in the coffee-shop shooting.

Police planned to arrest more people who helped Clemmons.

"We expect to have maybe six or seven people in custody by the day's end," said Ed Troyer, a spokesman for the Pierce County sheriff. "Some are friends, some are acquaintances, some are partners in crime, some are relatives. Now they're all partners in crime."
