SEATTLE - Steven Powell's daughter said her father's failed motion to suppress evidence in the voyeurism and child pornography case against him means the truth about his behavior will finally be revealed.
Jennifer Graves, the sister of Josh Powell and the most outspoken member of Steven Powell's family, has said she believes both Josh and Steven Powell had some role in the disappearance of Josh's wife, Susan.
"I think that he belongs behind bars," she told KIRO 7 Eyewitness News reporter Kevin McCarty, speaking by phone from her home in Utah. "He has committed some crimes and he has obviously abused other people, and it's time to stop that."
Graves said her father is responsible for years of abuse within her family, that he supplied pornography to her brothers Josh and Michael, and that he abused her mother, who split with Steven Powell in a lengthy, contentious divorce after 19 years or marriage.
"I look back, and I wonder why it took so long, but I don't know all the details and all the emotions that she went through," Graves said.
Graves said she is writing a book about her father, the disappearance of Susan Cox Powell and the murder-suicide committed by her brother, Josh, who killed himself and his sons Charlie and Braden in an explosion and fire at a home in Graham in February.
"It will be about me growing up with my dad, with my brother Josh -- the perspective on that, my perspective on this whole thing that has happened with Susan," she said.
Graves said she could be called to testify against her father at his upcoming trial. She said she hopes he will decide instead to plead guilty to the charges against him.
