Guardian UK: FBI finds 2,000 human bones at Indiana home: 'Unlike anything we’d ever seen' - Bones were found to be a part of a collection of over 40,000 artifacts in the home of Don Miller, an artifacts collector

The FBI determined that half of Miller’s collection was Native American artifacts. Almost all the human remains are believed to be from Native American burial sites.

Native American burial sites are protected under the Native American Graves Protection and Repatriation Act, which gives the right to determine what to do with artifacts found in burial sites and to those connected to their lineage. Archaeological digs of burial sites must also receive approval under the statute.
