Rebecca's death was ruled a suicide by the San Diego Sheriff's Department last week, a finding that her family categorically disagrees with.
Rebecca's sister, Mary Zahau tells RadarOnline.com: "There is no way my sister EVER would have killed herself. We have set up a website, and are seeking donations from the public so that we can hire our own private investigators to look into Rebecca's death.
“We need help from the public, who have been supportive of our family through this tragedy."
The Zahou family has hired Seattle based attorney, Anne Bremner.
