TACOMA, Wash. (AP) - Documents unsealed today reveal that authorities investigating the 2009 disappearance of a Utah woman found her blood in the family home and a hand-written note expressing fear about her husband.
    
The files raise further questions about why Susan Powell's husband was never charged in her disappearance before he killed himself and their two young sons in February.
    
The documents were used as justification to search the home where Josh Powell was staying last year.

They detail a widespread case that investigators had built against him.
    
They say shortly after Susan Powell disappeared, authorities found blood on a floor next to a sofa and determined it was hers.
    
Investigators found several life insurance policies on Susan Powell that totaled $1.5 million and determined that Josh Powell had filed paperwork to withdraw her retirement account money about 10 days after her

disappearance.
    
And they say a safety deposit box used by Susan Powell contained a hand-written letter she wrote saying she didn't trust her husband and that they'd been having marital troubles.

It also said that "if Susan Powell dies it may not be an accident, even if it looks like one."
