Requires certain police departments to establish a missing person's unit

HB 959 requires police departments in Missouri counties with over 1 million residents to create dedicated missing persons units. These units must coordinate reports, share information through state systems like MULES and NCIC, establish communication protocols for missing persons cases, and collaborate with the state highway patrol’s missing persons unit. Departments may hire new staff or reassign current employees using their existing annual operating budget, with no new state funding required. This bill directly affects large-county police departments but does not apply to smaller jurisdictions.
