In the second of a two-part Dr. Phil series exploring the suspicious death of a woman at a Coronado mansion in July, a prominent pathologist weighed in with his opinion but offered no surprises. Click here for Gore's complete statement On Monday, a private investigator hired by the Zahau family countered the suicide determination made by the San Diego County Medical Examiner's Office."This is ridiculous. This is so staged," said private investigator Paul Ciolino.Ciolino added his probe showed there was nothing to indicate that Zahau committed suicide.Ciolino told 10News he believes Zahau was strangled and did not hang herself."Let me tell you, I don't think this girl was ever hanging," said Ciolino. "When the police get there, she's laying in the yard in pristine condition."He believes she was strangled and placed on the lawn beneath the balcony.Ciolino said if she had hanged herself, the injuries to her body would have been much worse."She should've had at the very least a broken neck," he said.During the program, Zahau-Loehner, repeated what she's been saying since the San Diego County Sheriff's Department investigation concluded Rebecca killed herself, despondent over the impending death of her boyfriend's son: it was a homicide staged to make it look like suicide."My sister was killed, and somebody staged it to make it look like she did it to herself," said Zahau-LoehnerZahau's relatives and friends have refused to accept the ruling, saying she was a religious woman who viewed suicide as a sin and a modest person who never would allow herself to be publicly seen without clothing."As soon as I found out that she was naked and she was bound, it confirmed my fear that she did not commit suicide," Zahau-Loehner said. "She was murdered."Zahau-Loehner said she had no clear idea about who might have committed the alleged slaying.Zahau-Loehner said her sister's behavior in the days leading to her death was not consistent with that of someone driven to self destruction by what happened to Max Shacknai."She felt horrible, and she said it was something she couldn't have prevented," Zahau-Loehner said. "But she did not feel guilty about it."Zahau "never indicated that she felt responsible for Max's fall," added Doug Loehner.Attorney Anne Bremner, who is representing the Zahau family, claimed the sheriff's investigation missed several items that should have been clues to a murder, among them the discovery of a pair of women's panties in the guest bathroom and a pair of black gloves found at the mansion.Bremner also claimed that Rebecca Zahau's computer was used after her death, indicating that someone else had been there.Other key parts of the case remain unexplained as well, Zahau-Loehner told McGraw."They don't know were the rope came from," she said. "There were two knives in the room. One knife had her fingerprint; but the other knife is clean of prints. The knife had to get there somehow."Although the experts on the Dr. Phil show all indicated they believe Zahau's death was a homicide, no evidence was introduced to prove it.San Diego County Sheriff Bill Gore has repeatedly said that if new evidence comes forward, the Zahau case will be re-opened.The San Diego County Sheriff's Department released the following statement on Monday afternoon regarding the findings revealed on the Dr. Phil show: "To date, neither our detectives nor the Medical Examiner's Office have been presented with any evidence from this second autopsy. If Dr. Wecht or Miss Bremner would like to share information they believe is pertinent with our investigators, we would be glad to meet with them, rather than hear their results on television provided as entertainment." The California Attorney General's Office also denied a request for an independent inquiry at the state level.
