MS HB377

Requires local law enforcement agencies to accept missing person reports without delay and prohibits refusal based on age, time missing, circumstances of disappearance, or relationship of the reporting individual to the missing person.

Mandates entry of missing person information into the National Missing and Unidentified Persons System (NamUs) within 5-15 days if the person remains missing, with high-risk cases requiring entry within 5 days.

Defines "high-risk missing person" to include those missing under suspicious circumstances, stranger abductions, individuals under 21, those with mental impairments or dementia, veterans with service-related conditions, and persons missing more than 5 days.

Authorizes law enforcement to collect DNA samples from missing persons or family members for submission to NamUs partner laboratories and national DNA databases, with samples prohibited from retention after identification without a court-issued search warrant.

Requires the Mississippi Department of Public Safety to immediately notify all local law enforcement agencies statewide and in surrounding regions when a high-risk missing person is reported to aid in prompt location and safe return.
