When it comes to treasure, Indiana has become synonymous with the mysterious story of Don Miller.
A member of the Army Reserve, Miller spent much of his life traveling the world and illegally amassed a stash of 42,000 priceless artifacts in the process. In 2014, when Miller was in his early 90s, a SWAT team (including a helicopter) from the FBI Art Crime Department surrounded his farm to investigate what exactly he was hoarding.
The uncovered haul included cultural artifacts and figurines from China (pictured), all of which had to be returned. The FBI also discovered around 2,000 human bones, which had been taken from Native American burial sites. Miller died nearly a year after the raid and was never charged.
