MS HB343

Requires all local law enforcement agencies to accept missing person reports without delay or preconditions, including for adults, voluntary disappearances, or cases lacking apparent foul play.

Mandates law enforcement to enter missing person information into National Crime Information Center (NCIC) and National Missing and Unidentified Persons System (NaMUS) within 10 days for standard cases or 5 days for high-risk missing persons.

Permits law enforcement to obtain DNA samples from missing persons or family members for submission to state and national DNA databases, with samples retained only with a search warrant after the person is located or identified.

Defines "high-risk missing person" to include cases involving stranger abduction, suspicious circumstances, persons under age 21, those needing medical attention, abductions by noncustodial parents, and other factors indicating risk of injury or death.

Requires Mississippi Department of Public Safety to immediately notify all local law enforcement agencies within the state and surrounding region of information about high-risk missing persons and establish procedures for prioritizing DNA sample analysis.
