Serial killer David Maust who was sentenced to life in prison for murdering three teens and burying their bodies in a basement died Friday, a day after he was found hanging from a twisted bed sheet in his jail cell... Jail guards had found Maust, 51, hanging in his cell early Thursday, about 10 minutes after they told him that he was going to be transferred to a state prison later that day... Higgins said Maust used a bed sheet braided into a rope to hang himself. In a note found by the guards, Maust admitted to five killings.
