Background
Christian Jessee and John Gilmartin were affiliated with rival Davenport gangs but had previously served time together without problems. At a June 2023 gathering, Gilmartin greeted Jessee as an “opp,” meaning opposition. Gilmartin later texted his girlfriend that someone at the gathering had “upped” a “switch,” which she understood to mean that the person had pulled a gun on him. He also wrote that he and the person had been “locked up” together and were cool then, “but it’s different out here.”
Gilmartin left the gathering on foot and was fatally shot shortly afterward. Evidence connecting Jessee to the shooting included surveillance footage of his vehicle, incriminating messages found on his phone, Gilmartin’s texts, and a recorded jail call in which Jessee said that he and Gilmartin had been in prison together without problems. A jury convicted Jessee of first-degree murder, assault while participating in a felony causing serious injury, criminal gang participation, and being a felon in possession of a firearm. On appeal, Jessee challenged only the admission of evidence that he had previously been incarcerated.
The Court’s Holding
The Iowa Court of Appeals held that the district court did not abuse its discretion by admitting the two limited references to Jessee’s prior incarceration. Applying Iowa Rules of Evidence 5.403 and 5.404(b), the court found the evidence substantially probative because identity was the central disputed issue. The victim’s text helped explain the distinctive relationship and renewed hostility between the men, while Jessee’s jail call linked him to the person described in the text.
The court also found that the danger of unfair prejudice did not substantially outweigh the evidence’s probative value. The State mentioned the prior incarceration only briefly, did not disclose why Jessee had been imprisoned, and did not use his criminal history to argue that he was predisposed to commit the charged offenses. Because the defense suggested other possible perpetrators, the State’s need for evidence identifying Jessee as the person involved was heightened. The court affirmed all four convictions.
Key Takeaways
- Limited evidence of prior incarceration may be admitted when it serves a specific, non-character purpose such as establishing identity, motive, or the relationship between the defendant and victim.
- The prosecution’s need for identification evidence increased when the defense suggested that someone else may have committed the shooting.
- Brief prison references were not unfairly prejudicial where the State did not reveal the underlying offense or argue criminal propensity.
Why It Matters
The decision illustrates the contextual nature of Iowa’s Rule 5.403 balancing. Even evidence carrying an obvious risk of stigma may be admissible when it explains a distinctive relationship central to identifying the perpetrator and when less prejudicial alternatives would omit important context.
For trial lawyers, the opinion also underscores that the manner in which prior-bad-acts evidence is presented matters. Restricting the evidence to brief references, without identifying the earlier crime or inviting a propensity inference, can reduce the danger of unfair prejudice.
