Dina Shacknai, the mother of six-year-old Max Shacknai who tragically died last summer at his father's Coronado mansion, is suing the San Diego Medical Examiner's office to obtain his autopsy photos because she doesn't believe that he died by falling and hitting his head, RadarOnline.com is exclusively reporting.

As we previously reported, Rebecca Zahau, the girlfriend of Dina Shacknai's ex-husband Jonah Shacknai, killed herself just days after Max's fatal accident.

A top pathologist has slammed the ruling of suicide in the death of Rebecca Zahau, and stated that he is leaning strongly towards the cause of death being homicide.

Dr. Phil McGraw pledged to help get to the bottom of Zahau's mysterious death at her billionaire boyfriend's San Diego mansion by exhuming her body and performing a second autopsy — he aired the results of the examination on Tuesday, and RadarOnline.com has footage of the latest developments.

As RadarOnline.com previously reported, Rebecca's tragic death was ruled a suicide after her naked body was found hanged with her hands and feet bound at Jonah Shacknai's historic mansion on July 13.

Dina Shacknai's twin sister, Nina Romano was at the Coronado mansion in the hours leading up to Rebecca Zahau's death, RadarOnline.com is reporting.

The Dr. Phil Show about Rebecca Zahau's mystery death will be airing next week over two days, RadarOnline.com is exclusively reporting.

Rebecca's tragic death was ruled a suicide after her naked 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.

The historic  mansion where Rebecca Zahau’s body was found hanged this summer has been sold by the billionaire owner Jonah Shacknai, who was her boyfriend at the time of her death.

Shacknai’s six-year-old son Max had an accident in the home on July 11, and two days later Zahau, 32, who had been taking care of the young boy at the time of his accident, was found hanging naked from a balcony of the historic mansion. 

Max tragically passed away a few days later and the San Diego Police Department and Coroner’s office controversially ruled Rebecca’s death a suicide.

A second autopsy has been performed on Rebecca Zahau, the woman found hanged at her billionaire boyfriend's home.

The pretty 32-year-old was found naked and bound at Jonah Shacknai's Coronado mansion July 13, with her death being ruled a suicide by the San Diego County Medical Examiner.

But her devastated family does not believe she took her own life and wanted to have a new, independent autopsy in their search for evidence of foul play.

Zahau's body was exhumed and flown to Pittsburgh for the procedure performed by famed pathologist Dr. Cyril Wecht.

"I have some questions which I shall keep in mind," said Wecht. "But I want to make it clear that I'm not undertaking this with preconceived conclusions."

Zahau was found dead just days after her boyfriend's six-year-old son, Max, took a devastating fall while under her care.

Officials claim she committed suicide because she was so grief stricken about Max.  She'd learned he was not expected to survive just hours before her own lifeless body was found. Max died two days later.

Her family has never accepted that she took her own life. They've appealed to Dr. Phil to help get the case reopened. The results of this new autopsy will be revealed on an episode of his show next month.
