Modifies provisions relating to the sexual offender registry

HB 2311 modifies Missouri's sexual offender registry laws by updating age thresholds for certain offenses (e.g., changing "under 17" to "under 18" for statutory rape and child molestation). It specifies who must register (including those convicted of sexual offenses, child abuse, or equivalent federal crimes), requiring registration within three business days of adjudication or release. The bill establishes tiered registration periods: 15 years for Tier I offenders, 25 years for Tier II, and lifetime for Tier III, with potential reductions after 10 or 25 years of maintaining a clean record. This directly affects individuals convicted of specified sex offenses who reside in, work at, or attend school in Missouri.
