KELLY, Circuit Judge.

      When a litigant bypasses a district court’s discovery deadlines and belatedly
attempts to introduce new evidence, the court has broad discretion to fashion an
appropriate remedy. In this case, the district court1 concluded that the proper remedy

District of Missouri.
was excluding the late evidence. Reviewing under 18 U.S.C. § 3731, we conclude
that decision did not exceed the court’s discretion, and we affirm the judgment.

                                   I. Background

       In June 2013, Robin Sims was arrested and charged with, among other things,
being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1). On
August 21, 2013, a magistrate judge ordered that the government disclose all expert
testimony to Sims by April 10, 2014, seven days before the final pretrial conference.
Trial was set for April 28, 2014, 18 days after the disclosure date.

        Immediately after arresting Sims, police officers sent a gun seized from him to
a crime lab in Kansas City, Missouri, for DNA testing. An analyst at the lab,
however, mistakenly believed that the lab did not have a DNA sample from Sims on
file, so she could not compare his DNA to the DNA found on the gun. The analyst
e-mailed a detective and informed him that she could not make the comparison, but
the detective did not respond. Nor did the analyst hear from the federal prosecutors
assigned to Sims’s case.

       Meanwhile, Sims and the government had been discussing a potential plea, and
the discovery deadline for expert testimony passed. On April 14, 2014, two weeks
before the trial date, Sims’s lawyer told the government that Sims had decided not to
plead guilty and had, instead, opted for trial. It was only then that the government
contacted the crime lab and requested information about the status of the tests on the
DNA taken from the gun. The lab then located a DNA sample from Sims that it had
all along, and the government requested expedited testing. The government did not
tell the court or Sims that it was awaiting DNA evidence, did not update its
expert-witness list, and told the court at the April 17 pretrial conference that it was
“definitely ready for trial.”



                                         -2-
       On April 21, one week before the trial was to begin, the lab sent the
government a report, which stated that Sims was the source of “the majority of the
DNA on the gun” and that the chances of someone else having the same genetic
pattern as Sims was “one in 64 quintillion.”

      The next day, April 22, the government sent Sims’s attorney a copy of the lab
report and the name and credentials of the expert witness the government would
present at the trial. The government also filed a “Supplemental Notice of Expert
Witnesses” that disclosed the new DNA expert witness. The same day, Sims moved
to exclude the DNA evidence because of the late notice and argued that the
government should have requested the lab results sometime in the preceding eight
months instead of waiting until the week before trial. Sims asserted that he was
prejudiced by the late disclosure because he had no time to review the evidence from
the government, prepare questions for cross examination of the new witness, or hire
his own expert to review the new evidence.

       On April 24, the government responded by moving to continue the trial until
June 9, 2014, a date within Sims’s speedy-trial deadline, to give him time to review
the new evidence. The same day, the government also filed a second supplementary
notice of expert witnesses, naming two additional forensic specialists from the DNA
lab in Kansas City.

       The district court held a pretrial conference on April 25, 2014, during which
the parties discussed Sims’s motion to exclude the DNA evidence. Sims argued that
the government was at fault for failing to contact the lab until after the April 10
deadline to disclose expert witnesses. Even with the report disclosed, Sims added,
the government had not turned over the expert’s notes, so he could not know the basis
for the expert’s opinion. Sims noted the damaging nature of the expert’s report and
argued that a continuance was an insufficient remedy. The government responded



                                         -3-
that it had disclosed the evidence as soon as it received the report and insisted that a
continuance was a “perfect alternative remedy” to exclusion of the evidence.

       The district court sustained the motion and excluded the testimony. The court
noted that, although the delay stemmed from the lab, the government was using the
lab, “and if they can’t do their work, then you pay the consequences.” Because the
government had failed to check on the DNA testing, which began in the summer of
2013, the court ruled that the government also was responsible for the delay. Had the
government acted diligently, the court explained, “any confusion about a sample from
Defendant” promptly would have been resolved. The court ruled that the government
thus acted with reckless disregard for the expert deadline. The court also determined
that the evidence would cause “extreme prejudice” to Sims, and that it was
“unconscionable” for the government to introduce the evidence only days before the
trial. The court rejected the government’s proposal for lesser sanctions, concluding
that exclusion “is the only way to remedy the prejudice” to Sims “and to deter future
discovery violations.” The government requested an interlocutory appeal.

                                    II. Discussion

       On appeal the government maintains that the district court’s exclusion of the
DNA evidence was too harsh a sanction and asserts that the court should have used
“the least severe sanction which will adequately punish the government and secure
future compliance.” United States v. DeCoteau, 

, 1010 (8th Cir. 1999).
The government insists that a continuance was an adequate remedy because Sims
would have had time to review the evidence, hire an expert of his own, and prepare
for cross examination, and because continuing the trial would not have run afoul of
Sims’s right to a speedy trial.

      This court reviews the district court’s imposition of sanctions, and the court’s
choice of sanction, for abuse of discretion. United States v. Polk, 

, 249

                                          -4-
(8th Cir. 2013). A district court has broad discretion to sanction a party for failure
to comply with discovery orders. See United States v. Davis, 

, 670 (8th
Cir. 2001); Fed. R. Crim. P. 16(d)(2)(C) (providing for exclusion of evidence not
disclosed pursuant to discovery order). When reviewing whether the sanction
imposed evinces an abuse of discretion, we look at three factors: 1) the reason, or
reasons, for the delay in production of the evidence, including whether the
government acted in bad faith; 2) whether the defendant was prejudiced; and
3) whether a lesser sanction would secure future compliance by the government.
See United States v. Amaya, 

, 727 (8th Cir. 2014).

       With those principles in mind, we conclude that the district court did not abuse
its discretion. First, the district court concluded that the government had acted in
reckless disregard of the discovery deadline by failing to check on the DNA results
with the lab. This finding is supported by the undisputed fact that the government
informed the court at the April 17, 2014, pretrial conference that it was “definitely
ready for trial,” though it was awaiting the DNA results. Adding to that, the
government filed a second supplemental notice, after Sims had moved to exclude the
DNA evidence, attempting to add more expert witnesses. That notice was filed only
four days before the trial was set to begin and a full two weeks after the April 10
deadline. These actions confirm the district court’s conclusion that the government
showed more than just negligence in missing the discovery deadline.

      We also agree that Sims was prejudiced by the late disclosure. The DNA
evidence would have played a key part in Sims’s prosecution on the firearm charge.
By withholding that evidence, the government made it impossible for Sims to review
the new DNA evidence, prepare for cross examination, and hire his own expert
witness to rebut the conclusions made by the government’s expert before trial.

      Although it is possible, as the government suggests, that a continuance would
have alleviated some of the prejudice to Sims, the district court reasonably concluded

                                         -5-
that a lesser sanction would not “secure future compliance” with court orders.
See Taylor v. Illinois, 

, 413 (1988) (“It may well be true that alternative
sanctions are adequate and appropriate in most cases, but it is equally clear that they
would be less effective than the preclusion sanction . . . .”). Though the district court
did not have to remedy the situation by excluding the evidence and could have
imposed an alternative sanction, the court had discretion to impose the sanction it did.
See 

(concluding that district court did not abuse its discretion
by excluding evidence, rather than granting a continuance, because exclusion was
“the least severe sanction likely to remedy the prejudice and deter future wrongdoing
on the part of the government”); United States v. Wicker, 

, 1061 (10th
Cir. 1988) (noting need in some cases for district court to exclude evidence “to
maintain the integrity and schedule of the court”); United States v. Campagnuolo, 

, 858 (5th Cir. 1979) (finding no abuse of discretion where district court
suppressed evidence that government failed to disclose in violation of discovery
order). The district court’s decision to impose the harsher sanction in this case was
not an abuse of that broad discretion.

                                   III. Conclusion

      We affirm the judgment of the district court.
