A jury found John Barry Briley guilty of possessing counterfeit Federal Reserve Notes in violation of 18 U.S.C. § 472. On appeal, Briley argues that the district court abused its discretion in admitting certain evidence, and he challenges the sufficiency of the evidence supporting his conviction. For the reasons stated below, we affirm the judgment of the district court. 1
I.
After receiving a tip that an individual who drove a tan Dodge pickup truck was manufacturing methamphetamine out of a mobile home in Calion, Arkansas, the local authorities placed the residence under surveillance and obtained a warrant to search the home. Prior to executing the warrant, the authorities observed the defendant exit the mobile home and leave in a tan Dodge pickup. Officers trailed Briley to a convenience store near the main highway where Briley used a pay phone to place a call. The surveilling officers radioed Deputy Sheriff Ken Jones to inform him of their observations and whereabouts. Deputy Jones arrived shortly thereafter and began trailing Briley. When Briley began driving back toward his residence, Deputy Jones decided to stop him. He had no warrant for Briley’s arrest, nor did he observe Briley commit any traffic offense. Deputy Jones testified that he did not intend to arrest Briley and that he had stopped him because Jones was concerned about the safety of the officers executing the warrant: Briley had told the informant that the mobile home was “rigged to explode” and that if the police had tried to arrest him he could detonate the mobile home upon the push of a button. Deputy *363 Jones testified that he also wanted to inform Briley of the impending search and to request that he be present when the officers executed the warrant.
When Deputy Jones displayed his lights to initiate the stop, Briley fled, and a high-speed chase ensued. The chase ended after Briley lost control of his vehicle and crashed it into a brush pile near his residence. The defendant then attempted to flee on foot, only to be apprehended 50 to 70 feet from his truck. The authorities found a wallet on the ground between the truck and the point where Briley was apprehended. The wallet contained a counterfeit driver’s license with Briley’s picture but in the name of “Rodney Sterling” and a counterfeit $20 Federal Reserve Note.
Upon executing the warrant at Briley’s residence, the authorities found 48 additional counterfeit $20 notes in the pocket of a pair of jeans in the bedroom, a computer and color printer, and a printout containing the images of other counterfeit driver’s licenses. The next day, Deputy Jones relinquished custody of all the counterfeit currency to Secret Service Agents Racek and Harlan. The 49 counterfeit notes had only four different serial numbers. Agent Harlan counted and recorded the number of notes corresponding to each serial number and provided Jones with a receipt for the currency. Agent Racek initialed and dated the border of each note. Upon returning to the Secret Service office in Little Rock, Agent Racek sorted the notes into five envelopes: the single note found in Briley’s wallet was placed into one envelope, and the 48 other bills were placed into one of the four other envelopes each of which corresponded to one of the four different serial numbers. Agent Ra-cek also conducted a Mirandized interview with Briley, and Briley told the agent that he had produced the counterfeit notes on his home computer and that a Mr. Murphy had agreed to pay him 25 cents on the dollar for the counterfeit currency.
II.
Briley raises challenges to the admission of certain evidence. Specifically, he argues that the district court abused its discretion by admitting into evidence the 48 notes found in his residence because the government failed to establish a proper chain of custody, that the district court abused its discretion in admitting into evidence the contents of his wallet because they were the product of an illegal traffic stop, and that the district court abused its discretion in admitting into evidence the driver’s license found in his wallet, the computer, printer, and printout found in his residence because this evidence was irrelevant and more prejudicial than probative. We afford great deference to the district court’s evidentiary rulings, reversing only where there has been a clear abuse of discretion.
See United States v. Miller,
Briley first argues that the counterfeit notes contained in the five envelopes lacked a proper chain of custody and should not have been admitted into evidence. As a general rule, the district court may admit physical evidence if there is a reasonable probability that the evidence has not been changed or altered.
Id.
“Moreover, the integrity of such evidence is presumed to be preserved unless there is a showing of bad faith, ill will, or proof that the evidence has been tampered with.”
Id.
Briley has made no showing of ill will or tampering. Moreover, any defect in the chain of custody goes more to its weight than its admissibility.
United States v. Vallie,
Agent Racek's testimony created a reasonable probability that the counterfeit notes admitted into evidence were the same notes seized the night of Briley’s arrest. Agent Racek gave detailed testimony explaining the Secret Service’s internal tracking procedures to maintain the chain of custody for counterfeit notes and explained in great detail how the clerical error in this case occurred and was subsequently corrected. He also testified that despite these clerical errors, he was certain that the notes introduced at trial were the same notes seized because each of the 49 notes bore his initials and were dated. We thus conclude that the district court did not abuse its discretion in admitting the counterfeit notes into evidence.
See Miller,
Briley next contends that the district court erred in admitting into evidence the counterfeit bill and counterfeit license found in his wallet because both pieces of evidence were fruits of an illegal stop. We disagree. An investigative stop of a vehicle does not violate the Fourth Amendment where the police have a reasonable suspicion that the occupant of the vehicle is engaged in criminal activity.
United States v. Mora-Higuera,
Independently, even if the stop violated Briley’s Fourth Amendment rights,
*365
the admission of the evidence obtained was harmless beyond a reasonable doubt.
See Chambers v. Maroney,
We also reject Briley’s argument that the counterfeit license found in his wallet, the printout, and the computer and printer seized at his residence should not have been admitted into evidence because they were more prejudicial than probative. “In balancing the prejudicial effect and probative value, great deference is given to the district judge’s determination.”
United States v. Claxton,
Finally, we also reject Briley’s argument that the district court erred in denying his motion for judgment of acquittal based on the insufficiency of the evidence. “In evaluating the sufficiency of the evidence supporting a jury verdict against a defendant, we review the evidence in the light most favorable to the government and give the government the benefit of all inferences that reasonably may be drawn from the evidence.”
United States v. Reed,
III.
For the reasons discussed above, the judgment of the district court is affirmed.
