On Tuesday the FBI announced charges against 18 people for a variety of crimes on the Wind River Indian Reservation, including murder, sexual abuse, illegal drug distribution and violence against children.

The arrests are part of Operation Steadfast Promise, a multi-police agency taskforce the FBI started earlier in the year to target gang activity and violent crimes within Indian Country.

The Wind River Police Department worked with federal and state forensics experts and received training from the FBI’s Cellular Analysis Survey Team, which tracks cell phone data and locations.

Tribal police also analyzed more than 30 firearms with the Bureau of Alcohol, Tobacco, Firearms and Explosives.
