Existing law requires each sheriff or police chief executive to submit descriptions of serialized property, or nonserialized property that has been uniquely inscribed, which has been reported stolen, lost, or found directly into the appropriate Department of Justice automated property system for firearms, stolen bicycles, stolen vehicles, or other property. Existing law requires that information about a firearm entered into the automated system for firearms remain in the system until the reported firearm has been found. Existing law requires the Department of Justice to implement an electronic system to receive comprehensive tracing information from each local law enforcement agency and to forward the information to the National Tracing Center. This bill would require every person, with exceptions, to report the theft or loss of a firearm he or she owns or possesses to a local law enforcement agency in the jurisdiction in which the theft or loss occurred within 48 hours of the time he or she knew or reasonably should have known that the firearm had been stolen or lost, and requires every person who has reported a firearm lost or stolen to notify the local law enforcement agency within 48 hours if the firearm is subsequently recovered. The bill would make a violation of these provisions an infraction punishable by a fine not to exceed $100 for a first offense, an infraction punishable by a fine not to exceed $1,000 for a 2nd offense, and a misdemeanor, punishable by imprisonment in a county jail not exceeding 6 months, or by a fine not to exceed $1,000, or both that fine and imprisonment, for a 3rd or subsequent offense. The bill would make it a misdemeanor for any person to make a report to a local law enforcement agency that a firearm has been lost or stolen, knowing the report to be false.
