Ronnie Terrell Walters appeals the district court’s 1 order denying his motion for attorney fees and costs, which he filed after criminal charges against him were dismissed without prejudice. Following careful review, this court concludes that the district court did not abuse its discretion in denying Walters’s motion, given his failure to offer any evidence that the government’s position in prosecuting him was vexatious, frivolous, or in bad faith. See United States v. Monson, 636 F.3d 435, 438-39 (8th Cir. 2011) (standard of review; defendant’s burden of proof); United *720 States v. Porchay, 538 F.3d 704, 710 (8th Cir. 2008) (evidentiary hearing is not required unless serious factual disputes surround application for attorney fees).

The judgment of the district court is affirmed. See 8th Cir. R. 47B.
