Here is the unpublished opinion in United States v. Jones, for a crime committed on the Red Lake Reservation:
And the briefs:
Here, the district court did not procedurally err in considering Jones’s tribal convictions. The Guidelines specifically permit a district court to consider tribal court convictions for the purpose of determining the adequacy of a defendant’s criminal history, see U.S.S.G. § 4A1.3(a)(2)(A), and this court has consistently approved tribal convictions as a permissible basis for departing upward from the advisory Guidelines range. See, e.g.,United States v. Cook, 615 F.3d 891, 893 (8th Cir.2010);United States v. Harlan, 368 F.3d 870, 874-75 (8th Cir.2004).
