Rebecca Zahau's family is seeking donations so they can conduct their own investigation into her death, RadarOnline.com is exclusively reporting.

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.
