Read latest: Unsealed warrants reveal new details against Josh Powell

TACOMA, Wash. — Authorities investigating the 2009 disappearance of a Utah woman found her blood on the floor at her home, raising more questions about why her husband wasn't charged in her disappearance before he killed himself and their two young sons in a gas-fueled inferno in Washington state.

Court documents unsealed Friday show that blood found at Josh Powell's Utah home belonged to his wife, Susan Powell.
