The TRACE Act directs the Attorney General to add a data field to the National Missing and Unidentified Persons System that tracks whether a missing person was last seen on federal land, such as national forests, public lands, or Army Corps of Engineers projects. This change will help law enforcement and agencies better coordinate search and rescue efforts for people who disappear on federal property. Starting two years after the law takes effect, the Attorney General must submit annual reports to Congress every January 15th detailing how many missing persons cases involved federal land locations. The legislation defines federal land as property managed by the U.S. Department of Agriculture, Department of the Interior, or Army Corps of Engineers, but excludes tribal trust lands. This bill aims to improve tracking and awareness of missing persons incidents across the nation's federal lands and properties.
