Under court order, the FBI has released a trove of photos, videos, maps and other documents involving its secretive search for Civil War-era gold.

A lawyer for a father-son team of treasure hunters is accusing the FBI of either lying to a federal judge about having video of its 2018 dig for legendary Civil War-era gold, or illegally destroying the video.

A scientific analysis commissioned by the FBI shortly before agents went digging for buried treasure suggests that a huge quantity of gold could be below the surface of a rural site in western Pennsylvania.

Treasure hunters who believe they found a huge cache of fabled 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.

An FBI agent applied for a federal warrant in 2018 to seize a cache of gold that he said had been “stolen during the Civil War” while en route to the U.S. Mint in Philadelphia, and was “now concealed in an underground cave” in northwestern Pennsylvania.

FILE-This Sept. 20, 2018 file photo, Dennis Parada, right, and his son Kem Parada stand at the site of the FBI's dig for Civil War-era gold in Dents Run, Pennsylvania. Government emails released under court order show that FBI agents were looking for gold when they excavated Dent's Run in 2018, though the FBI says that nothing was found. FBI agents were looking for an extremely valuable cache of fabled Civil War-era gold — possibly tons of it — when they excavated a remote woodland site in Pennsylvania three years ago this month, according to government emails and other recently released documents in the case. The legal maneuvering generated emails between Newton and Audrey Miner, chief lawyer for the Pennsylvania Department of Conservation and Natural Resources. It's indicative, it's suggestive, but it can’t prove it.”To prove it, the FBI needed to dig.
