Newly released documents in the Susan Powell disappearance
show that her husband Josh Powell may have been responsible for her death – and that Susan had predicted her own tragic fate.
In the papers from the 2009 investigation
, which were unsealed on Friday, it is revealed that authorities discovered her blood in the Powell's West Valley City, Utah, home as well as a note in which she said she feared for her life, the Seattle Times reports
. Susan went missing
from her home in December 2009, and her body has never been found.
Josh was considered a person of interest
in Susan's disappearance, yet was never arrested. And the new documents raise further questions about why her husband, who killed himself and their two children
in a house explosion in February, was never charged with her disappearance, according to the Times
A safety deposit box used by Susan contained a last will and testament, life insurance policies totaling $1.5 million, and a chilling note that read "if Susan Powell dies it may not be an accident, even if it looks like one," the Times
reports, citing the documents. The papers also describe Josh Powell as unwilling to cooperate with the police investigation.
"There is direct evidence. There is circumstantial evidence. There is motive," Washington state prosecutor Mark Lindquist, who had a first look at the files, told the Times
. "There is everything but the body."
