Modifies provisions relating to the collection of DNA samples in criminal cases

HB 2868 requires certain individuals - including those convicted of specific felonies (like burglary or offenses under Chapters 565-566), sex offenders, and sexually violent predators - to provide DNA samples at defined legal milestones, such as jail booking, entry into correctional facilities, or sex offender registration. The law mandates collection without refusal at designated sites, with no additional samples needed if already in the state DNA database. It strictly prohibits unauthorized use of DNA records, requiring confidentiality for all stored data and outlining clear procedures for expungement if convictions are reversed or expunged. The bill applies to all Missouri law enforcement, correctional facilities, and agencies handling DNA collections under state and federal systems.
