1 TABOR, Chief Judge.

Before going to trial for murder and going armed with intent, Duval Walker Jr. moved in limine to exclude evidence of his “criminal history and any other charges stemming from this incident.” The district court granted his motion, preventing jurors from learning that he had a prior felony conviction and that he had pleaded guilty to being a felon in possession of a firearm for conduct during this incident. But potential juror R.L. saw a news alert about Walker’s guilty plea. When Walker moved to strike R.L. for cause, the district court refused, citing R.L.’s assertion that he had not formed an opinion that Walker was guilty of the other charges. And R.L. promised not to tell his fellow jurors what he had learned.

But because R.L. had information so prejudicial that it could not be offered as evidence or shared with other jurors, his exposure to the news account implanted actual bias. See Iowa R. Crim. P. 2.18(5)(o) (allowing challenges for cause “[w]here the circumstances indicate the juror would have an actual bias for or against a party”). Thus, the court abused its discretion by denying the motion to strike. Because Walker used a peremptory strike to remove R.L. and the court denied his request for an additional peremptory strike, we presume prejudice. The remedy is to reverse his convictions for murder and going armed with intent and to remand for a new trial.

I. Facts and Prior Proceedings

A St. Patrick’s Day brawl at a Marion bar ended in the fatal shooting of Cameron Barnes. Security cameras inside the bar showed the fight started when Walker punched Barnes in the face. After that, “all hell broke loose,” according to a witness. Bystanders jumped in, chairs were thrown, and pool

2 cues were broken. During the melee, a gun dropped on the ground. Walker picked the gun up, advanced towards Barnes, and shot him.

Walker was arrested two weeks later and charged with first-degree murder, felon in possession of a firearm, and going armed with intent. The case proceeded to a jury trial in March 2024. Before jury selection, Walker filed a written guilty plea to being a felon in possession. Because of that guilty plea—and Walker’s stipulation that he “was engaged in illegal activity at the time of the shooting”—the district court granted Walker’s motion in limine to exclude his criminal history.

At the start of jury selection, the prosecutor asked: “Has anyone seen or heard anything about this case prior to coming in here today?” Noting that “we have quite a few hands up,” the prosecutor and defense counsel engaged in individual voir dire of those prospective jurors. Among those examined were M.W. and R.L. After learning about their exposure to news accounts, Walker moved to strike both prospective jurors for cause, which the district court denied. Walker used two of his peremptory strikes to eliminate them from the jury.

The jury found Walker guilty of first-degree murder and going armed. Walker appeals.

II. Analysis

In this appeal from those convictions, Walker contends the district court abused its discretion in failing to grant his for-cause challenges. He also claims the court erred in refusing to instruct the jury on the doctrine of imperfect self-defense. We need only address the challenges for cause. We review denials of challenges for cause for an abuse of discretion. See State v. Jonas, 904 N.W.2d 566, 570 (Iowa 2017).

3 A. Framework

To obtain a new trial, Walker must prove three elements. See id. at 583. He must show that (1) the district court erred in denying his challenge for cause, (2) the denial caused him to use a peremptory strike on that prospective juror, and (3) he requested a replacement strike that was refused. Id. “Where the defendant makes such a showing, prejudice will then be presumed.” Id.

Walker followed this approach, using two of his peremptory strikes to remove potential jurors M.W. and R.L. who he unsuccessfully challenged for cause. Once he exhausted his strikes, Walker asked for two more and identified the jurors he would have removed if his challenges had been granted. The court denied that request, satisfying the second and third prongs of the Jonas presumed-prejudice approach. So we focus on the first prong: whether the court abused its discretion in denying Walker’s challenges for cause.

Iowa Rule of Criminal Procedure 2.18(5) lists available challenges for cause. Although Walker did not specify at trial which grounds he was relying on, he cites paragraphs (k) and (o) on appeal. See State v. Booker, 989 N.W.2d 621, 632 (Iowa 2023) (noting that while rule 2.18(5) requires the challenging party to “distinctly specify” the grounds for cause, the parties “were well aware of why” the for-cause challenge was raised).

We now examine those two grounds. Paragraph (k) allows a party to object if a prospective juror has “formed or expressed such an opinion as to the guilt or innocence of the defendant as would prevent the juror from rendering a true verdict upon the evidence submitted on the trial.” Iowa R. Crim. P. 2.18(5). Under this paragraph, the district court should grant the

4 motion if “the juror holds such a fixed opinion on the merits of the case that he or she cannot judge impartially the guilt or innocence of the defendant.” State v. Neuendorf, 509 N.W.2d 743, 746 (Iowa 1993) (citation omitted). Covering different territory, paragraph (o) applies “[w]here the circumstances indicate the juror would have an actual bias for or against a party.” Iowa R. Crim. P. 2.18(5) (effective July 1, 2022).

Because paragraph (o) is a recent addition to the rules of criminal procedure, we take this chance to discuss its origin and language. In summarizing the 2022 changes to the rules of criminal procedure, the Iowa Judicial Branch criminal procedure task force noted that this added challenge for cause arose from the supreme court’s decision in Jonas.1 In that case, our supreme court found that the district court abused its discretion in refusing to disqualify a potential juror for cause under paragraph (k). 904 N.W.2d at 575. During jury selection, that potential juror said he “would try to keep an open mind” but “would have a hard time overlooking” the fact that Jonas was gay. Id. at 569. As the court found, the potential juror should have been struck based on his original expression of “actual bias” against gay people, despite his “generalized statements the potential juror could be fair.” Id. at 571. Because paragraph (o) reflects this principle from Jonas, jurors’ assurances that they can be fair judges of the evidence—despite circumstances indicating bias—are not dispositive on this ground for disqualification.

Finally, we note that rule 2.18(5)(o) does not define “actual bias.” In deciding a post-trial claim of juror misconduct, our supreme court explained that jurors may be disqualified for either actual or implied bias. State v.
