Update: Report Reveals Other Injuries, Details in Coronado Mansion Death

Originally posted in September 2011.

Updated at 10:20 a.m. Wednesday: San Diego's CBS8 reports that an attorney for Jonah Shacknai has sent a letter threatening legal action to Rebecca Zahau's family attorney, accusing her of making “a series of inaccurate and utterly unsupported statements” about the case.

Investigators faced a barrage of questions Tuesday as criticism from Rebecca Zahau's family and outside experts mounted following .

Autopsy results show that Zahau, suffered other injuries that authorities did not mention in Friday's news conference about her death and that of Max Shacknai, 6, son of the home's wealthy owner, Jonah Shacknai.
, five days after a fall in the mansion while Zahau, Shacknai's girlfriend, was in the house; the 32-year-old woman's body was found nude and bound two days after his fall.

Zahau had blood on her legs, abrasions on her forehead and a contusion on her scalp that were not mentioned despite .

She also was found to have had tape marks on her legs, and a T-shirt around her neck that had been in her mouth, leading to questions about whether she could have been bound by other materials and if she had been gagged.

The Sheriff's Department released a statement Tuesday defending the investigation, with comments from Dr. Jonathan Lucas, who performed Zahau's autopsy.

He noted that “as in any comprehensive investigation, some findings cannot be entirely explained.”

Some people put materials in their mouths when they hang themselves, he said. The tape marks, he explained, were too small and “would have been unusual” as a sign of leg bindings.

The blood, he said, was due to Zahau's menstrual cycle or an intrauterine device, and the bruises, on the right side of her head, were “relatively minor.”

“None of the observations listed above are inconsistent with the conclusions reached regarding the cause and manner of death of Rebecca Zahau,” he said. Lucas determined Zahau died of asphyxia due to hanging; detectives said she tipped herself over the railing of a second-floor balcony. They said she had just found out about Max Shacknai's dire prognosis and was distraught. The woman's family continued Tuesday to press authorities to re-open the investigation. Zahau family attorney Anne Bremner told cable news host Dr. Drew Pinsky that the new details from the autopsy report were “really important things to look at” and warranted a new look.

The case was the focus of programming on the HLN network Monday and Tuesday, as hosts Jane Velez Mitchell and Nancy Grace also questioned the investigation's findings. Grace, known for her certainty that Florida mother Casey Anthony killed her daughter (Anthony was convicted of lesser charges in July), said Tuesday of the Zahau investigation, “We want this case re-opened. This is a murder.”

On Pinsky's program, Mary Zahau-Loehner, of St. Joseph, MO, denied that her sister would have written a perplexing message like the one painted on a Spreckels door that read, “She saved him, can he save her.” Detectives attributed the words to Zahau. She also referenced the family faith, and argued that Zahau believed committing suicide leads to damnation. “We believe that God is going to reveal at some point what happened to my sister,” Zahau-Loehner said.
