MO HB156

Offenders aged 16-17 at the time of first degree murder face either life without parole or a minimum sentence of at least 35 years imprisonment

Offenders under 16 at the time of first degree murder face either life without parole or a minimum sentence of at least 25 years imprisonment

Prosecutors must file notice if seeking life without parole for juvenile offenders, and courts must consider factors including victim impact, defendant's age, mental capacity, maturity, criminal history, and rehabilitation potential

Juvenile offenders previously sentenced to mandatory life without parole whose cases are still on appeal may file a motion within 6 months for resentencing under the new provisions

Declared an emergency act to take effect immediately, responding to U.S. Supreme Court decisions finding mandatory life without parole for juveniles unconstitutional
