By Daily Mail Reporter PUBLISHED: 16:23 EST, 14 July 2013 | UPDATED: 02:41 EST, 15 July 2013 The family of a woman found hanging, bound and naked, from the balcony in her boyfriend's California mansion have filled a $10million wrongful death suit claiming that she was murdered. Authorities ruled Rebecca Zahau's death July 13, 2011 a suicide. It was the second bizarre tragedy in days at the multimillion-dollar Spreckels Mansion in Conrado, California, which belonged to Zahau's boyfriend, Jonah Shacknai - the CEO of a pharmaceutical company. Just two days earlier, Shacknai's six-year-old son Max fell off a staircase in the home and was mortally inured. He died says later in the hospital. Zahau was the only adult home at the time.
