SAN DIEGO (KGTV) - A lawsuit filed in the death of 32-year-old Rebecca Zahau is making the case that her death was indeed a murder.
In a wrongful death lawsuit brought forth by Zahau's family, attorney Keith Greer said Sheriff's investigators incorrectly ruled Zahau's death as a suicide.
Rather, Greer said he believes the evidence points to the brother of Zahau's boyfriend, Adam Shacknai, who was staying at the guest house of where Zahau was found dead on July 13, 2011.
The family's lawsuit is against Shacknai.
"It isn't what was found that is so significant or unusual - it's what wasn't found," Greer said in a press conference Tuesday.
Greer believes the evidence shows fingerprints and DNA were cleaned off surfaces and handwriting of a mysterious note at the scene points to Shacknai.
The attorney also said evidence on a bloody knife indicates it was used to sexually assault Zahau.
"I got almost nauseous, It's already heinous what happened here to be stripped naked, bound gagged … it's already terrible. It seemed like it couldn't get any more shocking. My stomach flipped," Greer said.
The civil trial begins in February.
Zahau's death has captured headlines since she was discovered hanging nude from the second balcony of the Spreckels Mansion in Coronado six years ago.
This was just a couple days after her boyfriend's son, Max, fell down some stairs and died in what was considered an accident. At the time, Max was under Zahau's care.
When asked about the recent documents filed in court, a spokesperson for the Sheriff's Department said they are looking into it. The department will release an official comment once they have time to review the information.
Attorneys for Adam Shacknai did not respond to a request for a comment.
