OSBI is taking a new approach to helping solve cold cases with the help of the Department of Corrections (DOC). Recently, OSBI put 52 cold case homicides, missing persons, and unidentified victims on a deck of playing cards. Five thousand of the decks are being sold to inmates within DOC facilities. OSBI is working on a second edition with more cold cases from across the state.
