The TRACE Act mandates the Attorney General to enhance the National Missing and Unidentified Persons System (NamUs) by incorporating a new data field. This field will specifically record if a missing person's last known location was confirmed or suspected to have been on Federal land or within the territorial waters of the United States , including precise location details. Additionally, the legislation requires the Attorney General to provide an annual report to the Committee on the Judiciary of both the Senate and the House of Representatives. This report will enumerate the cases in NamUs where the missing person's last known location was identified as Federal land or U.S. territorial waters, thereby improving tracking and reporting for these specific circumstances.
