Treasure hunters demand answers from FBI about search for civil war-era gold

Finders Keepers lawsuit seeks confirmation that agency found trove in Pennsylvania after father-son team suggested location

Treasure hunters who believe they found a huge cache of fabled US civil war-era gold in Pennsylvania are now on the prowl for something as elusive as the buried booty itself: government records of the FBI's excavation.

Finders Keepers, a lost treasure locate and recovery service, filed a federal lawsuit against the justice department over its failure to produce documents on the FBI's search for the legendary gold, which took place nearly four years ago at a remote woodland site in north-western Pennsylvania.
