Ralph and Gabrielene Nishiyama, brought this action under 42 U.S.C. § 1983 against Dickson County, Tennessee, Sheriff Doyle Wall and Deputy Sheriff Carroll Fiser as well as Dickson County. The Nishiyamas allege the sheriffs' policy and practice of entrusting fully-equipped official patrol cars to inmate Charles Hartman, a convicted felon, deprived their daughter Kathy of her life without due process of law. Hartman was allegedly cruising alone in a patrol car when he stopped and then murdered Kathy Nishiyama. The district court dismissed the Nishiyamas' complaint for failure to state a claim pursuant to Rule 12(b)(6) of the Federal Rules of Civil Procedure.
