Authorities say a man told a Seattle TV newsroom that he had killed his wife and asked the station to post the message on its Facebook page.

KOMO reported Thursday (http://bit.ly/Z1GYVJ) that it notified police, who started a search that ended about 6 a.m. Thursday at a Tacoma motel where officers found the body of 42-year-old Sara Barrett.

Sheriff's spokesman Ed Troyer says she died of homicidal violence.

Hours earlier, police arrested 41-year-old Tony Barrett in Gig Harbor after a high-speed chase. They say he fought with a crowbar. He's in custody for investigation of murder.
