or 19-03.2 or within a reasonable time after the period, and there is no likely source for the property other than that offense.” There is evidence in this record supporting the court’s findings. We are not left with a definite and firm conviction the court made a mistake in its findings, and we conclude the court’s findings under N.D.C.C. § 19-03.1-23.3(l)(b) are not clearly erroneous.
[¶ 14] Moreover, N.D.C.C. § 19-03.1-23.3(l)(d) requires a transaction, and although Birkholz argues there is no evidence of a transaction, we conclude there is sufficient evidence to support an inference of a transaction. We are not left with a definite and firm conviction the district court made a mistake in finding the prerequisites for application of the forfeiture presumption under N.D.C.C. § 19-03.1-23.3(l)(d). We therefore conclude the court did not clearly err in ordering forfeiture of the currency.

[¶ 15] Birkholz argues the district court erred in denying his motion for a new trial on the ground of newly discovered evidence, which he claims is evidence about the proceeds of refinancing his house in 2004.
[¶ 16] A motion for a new trial on the basis of newly discovered evidence is addressed to the discretion of the district court and will not be overturned on appeal absent an abuse of discretion. Farmers Elevator Co. of Horace v. Nagel, 307 N.W.2d 580, 584 (N.D.1981). A district court abuses its discretion if it acts in an arbitrary, unreasonable, or unconscionable manner, its decision is not the product of a rational mental process leading to a reasoned determination, or it misinterprets or misapplies the law. Johnson v. Nodak Mut. Ins. Co., 2005 ND 112, ¶ 18, 699 N.W.2d 45. In Keyes v. Amundson, 391 N.W.2d 602, 605 (N.D.1986) (citations omitted), this Court outlined the requirements for a new trial on the basis of newly discovered evidence:
(1) the evidence must have been discovered following trial; (2) the movant must have exercised due diligence in discovering the evidence; (3) the evidence must not be merely cumulative or impeaching; (4) the evidence must be material and admissible; and (5) the evidence must be such that a new trial would probably produce a different result.
[¶ 17] This record reflects Birkholz testified at trial that he had previously talked with his attorney about refinancing his home. The record thus reflects Birkholz knew about the refinancing before trial. The district court denied Birkholz’s motion for a new trial, concluding there was no newly discovered evidence. We conclude the court’s denial of Birkholz’s motion for a new trial was not arbitrary, capricious, or unreasonable, and the court did not abuse its discretion in denying the motion.

[¶ 18] We affirm the judgment and the order denying the motion for a new trial.
