Rebecca's tragic death was ruled a suicide after her body was found hanged with her hands and feet bound, at her billionaire boyfriend Jonah Shacknai's historic Spreckles mansion in San Diego.
The death occurred just days after Jonah’s six-year-old son Max had an accident in the home, while under Rebecca’s care, that turned out to be fatal.
As RadarOnline.com has exclusively reported, Rebecca's family does not believe she committed suicide and have insisted that she was murdered,
and now Dr. Phil McGraw is going to have her body exhumed from her grave in Missouri and retested for any more evidence of foul play.
He will air the results on his show during the November sweeps season.
Dr. Phil has scored major interviews this season for his show, with George and Cindy Anthony as his first guests, and the Zahau family is hopeful that the tests will help them solve the mystery of what happened to Rebecca.
Despite what her family and their attorney say is overwhelming evidence that Rebecca was murdered, the authorities in San Diego closed the case into Rebecca's death but have told RadarOnline.com that if new credible evidence surfaces they would reopen an investigation into her death.
