Establishes the Sheena Henderson act.

Requires law enforcement agencies to: (1) Before returning a privately owned firearm, confirm that the individual to whom the firearm will be returned is the individual from whom the firearm was obtained or an authorized representative of that person and that he or she is eligible to possess a firearm; and

(2) Develop a notification protocol that allows a family or household member to use an incident or case number to request to be notified when a law enforcement agency returns a privately owned firearm to the individual from whom it was obtained or to an authorized representative of that person.

Prohibits a law enforcement agency from providing notification to any party other than a family or household member who has an incident or case number and who has requested to be notified or another criminal justice agency.
