Newly uncovered e-mails sent by missing Utah woman Susan Powell are giving a disturbing insight into the abuse she endured at the hands of her husband Josh Powell before she disappeared in December 2009, and RadarOnline.com has exclusive insight from her family’s attorney.

Published in the Salt Lake City Tribune on Sunday, the e-mails were sent by Susan to several co-workers, friends and members of her ward of The Church of Jesus Christ of Latter-day Saints, venting her frustration and pain over the state of her crumbling marriage.

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.

We've learned new details in the wake of the tragedy in Graham, Washington, where Josh Powell -- a person of interest in the two-year disappearance of wife Susan -- killed himself and his two young sons Sunday during what was to be a supervised visit with a social worker.

New overnight developments in the case reveal that Josh Powell had planned the home explosion that killed him for some time prior to Sunday; and even more shockingly, that the father murdered his two sons, 5-year-old Braden and 7-year-old Charles, with a hatchet prior to torching the home.

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.

Forensic expert Dr. Maurice Godwin, who was hired by Rebecca Zahau's family after the San Diego Sheriff's Department ruled her death a suicide, is no longer working with the family, and the renowned expert thinks Dr. Phil is the reason he was let go from the investigation, RadarOnline.com is exclusively reporting.

Rebecca's naked body was found hanging from a balcony at her boyfriend, Jonah Shacknai's Coronado mansion, two days after his son, Max, was found unconscious at the base of the stairs. Cops ruled Rebecca's death a suicide, something her family vehemently disagrees with. As RadarOnline.com previously reported, Dr. Phil is paying to have Rebecca's body exhumed, and an independent autopsy performed. Rebecca's sisters, and their attorney, Anne Bremner will appear on an upcoming episode of The Dr. Phil Show.

The San Diego County Sheriff's Department still hasn't turned evidence in the Rebecca Zahau death case over to her grieving family, RadarOnline.com is exclusively reporting.

Zahau's tragic death was ruled a suicide after her nude body was found hanging from the outside of her multimillionaire boyfriend Jonah Shacknai's mansion in Coronado, California.

Rebecca's death occurred two days after Jonah's six-year-old son, Max, was discovered unconscious at the base of the stairs of the historic Spreckles Mansion they all shared. Max subsequently died from his injuries, and his death was ruled an accident.

The anguished family of Rebecca Zahau has formally asked the California Attorney General to launch a full and independent investigation of the woman’s mysterious hanging, RadarOnline.com has exclusively learned.

In an email sent to Attorney General Kamala D. Harris on Wednesday, the family’s high-profile lawyer, Anne Bremner, said the Department should open a new probe because she had obtained "compelling evidence to be investigated" and "new critical witnesses to be interviewed."

“I will be respectfully submitting to you a formal and detailed response to Mr. Shacknai’s letter (which was not copied to me nor to my clients),” Bremner wrote.

There appears to be another mystery in the Rebecca Zahau suicide case that could re-open the investigation into the cause of her death, RadarOnline.com is exclusively reporting.

The San Diego Sheriff's Department determined the cause of Rebecca's death to be a suicide, after her naked body was found hanging from a rope at her billionaire boyfriend, Jonah Shacknai's mansion in Coronado, a posh suburb of San Diego.
