Parkland school shooter Nikolas Cruz has been in custody in the Florida Department of Corrections for the past nine weeks—but where exactly he’s being held is unknown. Florida has refused to reveal his location of the convicted murderer, who was sentenced to 34 life sentences in October after a high-profile trial. Many of the family members of the victims had hoped for a death sentence for the killer, who took the lives of 17 people in February 2018. Cruz’s hidden location may be linked to the state’s concern that other inmates could try and kill him, although the state hasn’t confirmed such a connection. “They’re going to do everything they can to keep him alive. Too many inmates have nothing to lose,” Ron McAndrew, a retired Florida prison warden, told the Orlando Sentinel.
