In 2011, Rebecca Zahau was found hanging naked from a balcony in the home she shared with her boyfriend. Her feet were bound, her wrists tied behind her back, and a T-shirt was used to gag her. Just a few weeks after finding her, police rule her death a suicide, saying she was distraught over an earlier tragedy but her family refused to believe she would kill herself in that way. In civil court, a man is found culpable of her murder. But did he really do it?
