Modifies provisions relating to jails

HB 667 repeals old Missouri jail statutes and creates a new framework allowing two or more contiguous counties to form regional jail districts. These districts would be governed by a commission of county sheriffs and commissioners, with member counties agreeing on cost-sharing formulas, the types of prisoners they can house (limited to those transferable under state law), and facility financing. The bill requires detailed written agreements outlining each county's responsibilities, budget procedures, and powers like land acquisition for jail facilities, while permitting counties to contract with regional districts for prisoner housing.
