Jurisdiction in Indian Country is based upon the unique sovereign relationship between the federal government and Indian tribes.  Congress has extended the territorial jurisdiction of the United States to major crimes committed against Native Americans that take place in Indian Country, which includes all property that the government holds in trust or use by officially recognized Native American tribes.  The U.S. Attorney’s Office prosecutes all major crimes and misdemeanor cases arising in Indian Country that are within the jurisdiction of this office.  The U.S. Attorney’s Office prosecutes cases arising in Indian Country involving felonies where either the defendant or the victim is an Indian or both the defendant and the victim are Indian.

The FBI, ATF, and the Coushatta Tribal Police Department conducted the investigation.  Assistant U.S. Attorney Joseph T. Mickel prosecuted the case.
