The group that recently occupied an Oregon refuge may have desecrated a culturally significant Native American site.

About a week ago, the last of the individuals occupying Oregon’s Malheur National Wildlife Refuge vacated the area, ending a 6-week standoff with authorities. 
Reuters reports that FBI investigators have discovered "significant amounts of human feces" while gathering evidence from the refuge.
A trench filled with feces was found either in or on an area known to contain artifacts of the Burns Paiute Tribe.
The bureau’s Art Crimes Team is assessing if and to what extent the ancestral grounds in particular were harmed.
