Modifies provisions relating to juvenile detention centers

SB 1189 modifies Missouri's laws governing juvenile detention centers, requiring counties to provide separate facilities for minors that prevent contact with adult inmates. It establishes new rules for counties to coordinate shared detention facilities across multiple counties within judicial circuits, with costs prorated based on population. The bill allows counties to impose an additional up to 1% sales tax to fund these facilities, while mandating that detention centers must provide care resembling "good homes" and be overseen by a superintendent appointed by the juvenile court. This directly affects counties (especially third and fourth class), juvenile courts, and children in detention.
