The sources said they suspect Maurice Clemmons' friends and family are trying to throw investigators off his trail as the 37-year-old tries to avoid capture.

Ever since Clemmons was named as a suspect in the fatal shooting of the Lakewood officers, police agencies have been inundated with calls and tips. Detectives said they now believe some false leads came from people trying to buy Clemmons time by keep search teams busy.

UPDATE 5:54 PM: The Seattle Times has a more authoritative report:

Maurice Clemmons has been getting help and shelter from friends and relatives since shortly after the Sunday morning shooting deaths of four Lakewood police officers, authorities have concluded.

"Basically, there's no way that he could be doing this by himself; he was shot in the abdomen," said Sheri Badger, Pierce County spokeswoman at the incident command center.

Also frustrating to law-enforcement officers is that Clemmons reportedly told acquaintances the night before the attack to "watch the news" because he was going to "kill cops.""
