Even before finding the blood, police didn’t believe Josh’s alibi. Who leaves for camping in the middle of the night during a blizzard, without scheduling time off work or even calling in sick, only to return less than a day later? Also, a phone call Josh made to Susan seemed staged. Adding to suspicions, Josh moved the boys back to Washington only a month after Susan disappeared, an action that seemed out of line for someone married to a missing person unless he knew her to be deceased.
As investigators would learn from friends and Susan’s own diaries, the young mother was unhappy in the eight-year marriage and even feared for her life. She had a handwritten will, dated June 28. 2008, which she addressed to friends and family, but specifically excluded her husband with the line “except for Josh Powell husband, I don’t trust him!”
The 28-year-old mother’s friends described a very controlling and abusive situation. For example, Susan was forced to give up her car and bike seven miles to work and back each day. She also expressed concern over her children ending up with Josh if something were to happen to her. And it appears her fear was completely justified.
