Modifies procedures relating to the detention of a juvenile

SB 1649 modifies Missouri's juvenile detention procedures to ensure faster court review and stricter criteria for holding minors. It requires that juveniles taken into custody be immediately brought before juvenile court or a juvenile officer, and mandates that courts review detention reasons within 24 hours. The bill limits detention to 24 hours without a hearing (with a 3-day deadline for the hearing), and specifies that continued detention is only permitted if the court finds probable cause for an offense and that detention is necessary to protect the juvenile, others, prevent flight, address lack of supervision, or handle fugitive status. This directly affects minors in custody, their families, and juvenile court processes.
