*532 OPINION

Reginald Hardy appeals from his conviction and sentence for possession of a firearm by a convicted felon. On appeal, he asserts that the district court erred by (1) denying his motion for a mistrial following statements made by an uncontrollable witness and (2) overruling his objection to the inclusion of one criminal history point based on hearsay rather than an official judgment order. We affirm.

The denial of a mistrial is reviewed for an abuse of discretion. United States v. Dorsey, 45 F.3d 809, 817 (4th Cir. 1995). To show an abuse of discretion, the defendant must show prejudice. Id. Hardy contends that witness Alfreda Hawkins’ testimony violated Federal Rule of Evidence 404(b), which prohibits prior bad acts evidence to show later action in conformity therewith. While the Rule provides for exclusion of such evidence admitted to show character, it does not require exclusion of such evidence offered to establish opportunity, motive, intent, preparation, plan, knowledge, identity, or absence of mistake. Fed.R.Evid. 404(b).

Here, while Hawkins’ unsolicited statements were unresponsive, there were only two occasions on which her statements could be construed as describing bad acts. However, since these comments also described Hardy’s actions and helped to prove that he knowingly and unlawfully possessed a firearm, the statements were not excludable under Rule 404(b).

Moreover, even assuming that the evidence was improper, Hardy has failed to show that he suffered prejudice from Hawkins’ testimony. The police testified that they found Hardy with the firearm lying between his shirt and the jeans that contained his wallet and within arm’s reach of where he was sleeping. Thus, even if Hawkins’ testimony were completely disregarded, there was still sufficient evidence from which the jury could have found Hardy guilty. Thus, Hardy’s motion for a mistrial was properly denied.

This court reviews the district court’s factual findings at a sentencing hearing for clear error. United States v. Lamarr, 75 F.3d 964, 972 (4th Cir. 1996). The party that objects to a finding in a presentence report has the burden of making an affirmative showing that the information is inaccurate. United States v. Love, 134 F.3d 595, 606 (4th Cir. 1998). In the absence of such a showing, the sentencing court may adopt the findings of the presentence report without further inquiry. Id.

Here, Hardy never claimed that he had not received the conviction, and he made no showing that the information in the presentence report was inaccurate. Thus, the trial court did not err by accepting the presentence report. In addition, the information in the report was sufficiently reliable. See id. at 607 (holding that uncorroborated hearsay evidence may be properly considered at sentencing). Accordingly, there was no error in calculating Hardy’s criminal history.

Thus, we affirm Hardy’s conviction and sentence. We dispense with oral argument, because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED.
