The devastated family of Rebecca Zahau -- the woman who police say committed suicide at her billionaire boyfriend’s mansion in Coronado, California -- says Rebecca’s personal belongings haven’t been returned to them, and they won’t be until a judge releases them.

“The police still have Rebecca’s computer and cell phone,” Snowem Horwath, Rebecca’s sister, exclusively told RadarOnline.com.  “We want Rebecca’s things back so that nothing can happen to them.”

The San Diego Sheriff’s Department held an extensive news conference on Friday, announcing their belief that Rebecca committed suicide and that the case was closed, so the family expected that they would have their beloved Rebecca’s things back.

The family of Rebecca Zahau, the woman found hanging at billionaire Jonah Shacknai’s home in July, doesn’t want the police to close the case on her death RadarOnline.com has exclusively learned. 

“Rebecca had no history of suicidal tendencies, no psychological problems and no history of depression,” high profile lawyer Anne Bremner, who is representing her family, exclusively told RadarOnline.com.  “The family wants justice. The police have a duty to fully investigate the case and we don’t want them to close the investigation today. The family does not believe it was a suicide.”

As RadarOnline.com exclusively reported, Zahau’s sister believes her sister was murdered. “Becky did not kill herself, someone killed her,” Snowem Horwath said.  “Time will reveal who killed Becky.  I think I know who killed my sister.  We are not stupid, she never had any enemies.”

The girlfriend of San Diego billionaire Jonah Shacknai did not kill herself, she was murdered, her family is insisting in an exclusive interview with RadarOnline.com.

Rebecca Zahau was found nude and hanging from an outside balcony at her boyfriend’s mansion on July 18, and while the Medical Examiner’s Office is ruling her death a suicide her family says she was murdered and they believe they know who did it.

“Becky did not kill herself, someone killed her,” Snowem Horwath, Rebecca’s sister, exclusively claimed to RadarOnline.com. “Time will reveal who killed Becky.  I think I know who killed my sister.  We are not stupid, she never had any enemies.”

The San Diego Medical Examiner’s Office and the Coronado Police Department will be holding a press conference at 2 p.m. EST to reveal their findings regarding the death of Rebecca Zahau and RadarOnline.com will be live streaming the event.

Rebecca was found naked and bound hanging from an outside balcony at her billionaire boyfriend Jonah Shacknai’s home in San Diego on July 18, just days after his little son Max was found unconscious in the home.

As RadarOnline.com has exclusively reported, her sister said the family believes she was murdered and their lawyer doesn’t want the police to close the case.
