Background
On the evening of June 16, 2024, Isaac Bachman and a minor engaged in a prolonged, hostile exchange over a messaging application that included name-calling, threats, and Bachman daring the minor to come to his home. As the confrontation escalated, Bachman retrieved a rifle from inside his house and waited in his backyard. When the minor arrived and reached the gate, Bachman opened it and, as the minor came into view, shot him multiple times. The autopsy confirmed four bullet wounds to the minor’s neck, chest, and abdomen; the minor died from his injuries.
Bachman initially told law enforcement he acted in self-defense, claiming the minor was trying to break in and had slammed the gate into his face. However, two eyewitnesses who were present in the backyard testified at trial that Bachman had coached them to say it was self-defense, and one witness heard Bachman declare afterward, “I will kill anyone for you.” Bachman’s own descriptions of how he operated the bolt-action rifle — manually cycling a new round before each of the four shots — and his post-arrest jail messages, which were interpreted as bragging about the shooting, further undermined his account. A jury in Webster County convicted Bachman of first-degree murder, and he was sentenced to life in prison without the possibility of parole.
Bachman moved for a new trial, arguing that two jury instructions were defective: first, that the marshaling instruction for first-degree murder (Instruction 19) failed to list lack of justification as an element the State was required to prove; and second, that an instruction permitting the jury to infer malice, premeditation, and specific intent from deliberate use of a dangerous weapon (Instruction 21) violated his right to keep and bear arms under the Iowa Constitution. The district court denied the motion, and Bachman appealed.
The Court’s Holding
The Iowa Court of Appeals affirmed the conviction, finding no error in either challenged instruction. On the justification issue, the court held that justification is an affirmative defense, not an element of first-degree murder, and that the marshaling instruction was not required to list it as such. The court reasoned that the instructions, read as a whole, adequately informed the jury: the marshaling instruction cross-referenced the justification defense by stating Bachman was guilty “unless you find the acts justified as set forth later in these instructions,” and a separate instruction (No. 45) expressly told the jury that “[t]he State must prove beyond a reasonable doubt that [Bachman]’s use of force was not justified.” Both parties reinforced this framework in closing arguments, with defense counsel explicitly telling the jury that the State bore the burden of disproving justification.
On the dangerous-weapon inference, the court rejected Bachman’s argument that Iowa’s 2022 constitutional amendment establishing a fundamental right to keep and bear arms — subject to strict scrutiny — invalidated the longstanding permissive inference that deliberate use of a deadly weapon resulting in death supports an inference of malice, premeditation, and specific intent to kill. The court held that the inference survived the constitutional amendment, noting that existing Iowa Supreme Court precedent endorsed the inference, that the Second Amendment has never been interpreted to protect carrying arms for any sort of confrontation, and that the instruction was permissive — the jury was told it “may, but are not required to,” draw the inference.
The court also addressed harmless error, concluding that even if any instructional error had occurred, the overwhelming evidence of guilt — including video footage of the shooting, Bachman’s deliberate arming and positioning before the minor arrived, his post-shooting statements, and his jail messages — would have precluded any prejudice to Bachman.
Key Takeaways
- Justification is an affirmative defense in Iowa, not an element of first-degree murder; a marshaling instruction need not list it among the elements so long as the jury instructions as a whole, including cross-references and a standalone justification instruction, correctly state the State’s burden of disproving justification beyond a reasonable doubt.
- Iowa’s 2022 constitutional amendment elevating the right to keep and bear arms to a fundamental right subject to strict scrutiny does not abrogate the longstanding permissive inference that deliberate use of a dangerous weapon causing death, after an opportunity to deliberate, supports an inference of malice, premeditation, and specific intent to kill.
- Iowa’s justification defense does not authorize the use of a firearm in what the defendant himself acknowledged was anticipated to be a fist fight.
- Strong evidence of guilt — including incriminating post-shooting statements, coaching of witnesses, and video footage — can overcome the presumption of prejudice that attaches to alleged instructional error.
Why It Matters
This decision clarifies the interplay between Iowa’s justification defense and the structure of murder jury instructions, confirming that courts need not embed the lack-of-justification element within the marshaling instruction itself, provided the full instruction set unambiguously places the burden on the State. Defense practitioners should note that cross-references to standalone justification instructions, combined with closing argument, will generally satisfy due process — but the decision also highlights the risk of instructional challenges where the jury instructions are not carefully coordinated.
The court’s rejection of the Second Amendment challenge to the dangerous-weapon inference is also significant. As Iowa’s 2022 right-to-bear-arms amendment continues to generate litigation, this decision signals that the courts of appeals are unwilling to extend its reach to undermine settled evidentiary inferences in murder prosecutions. Defendants who use firearms in homicide cases cannot invoke the constitutional right to bear arms to shield the jury from drawing common-sense inferences about state of mind from that use.
