Requires the Missouri state highway patrol to investigate any incident occurring in St. Louis city or St. Louis county in which a law enforcement officer is involved in a shooting or incident resulting in death

HB 3042 requires the Missouri State Highway Patrol to investigate any officer-involved shooting or incident resulting in death within St. Louis City or St. Louis County. It specifically covers cases where law enforcement officers use force against civilians causing death, or civilians use force against officers causing death. The bill mandates that local law enforcement agencies reimburse the Highway Patrol for all investigation costs incurred. This bill directly affects St. Louis City and County law enforcement agencies and the Missouri State Highway Patrol by shifting investigation responsibility to the state agency. The bill is currently in early stages (introduced January 2026) and has not yet been voted on.
