Opinion

IN THE COURT OF APPEALS OF IOWA

No. 24-0169 Filed September 4, 2025

STATE OF IOWA, Plaintiff-Appellee,

vs.

DILLON MICHAEL HEILLER, Defendant-Appellant. ________________________________________________________________

Appeal from the Iowa District Court for Allamakee County,

John Bauercamper, Judge.

A defendant challenges his convictions for theft in the first degree and theft

in the second degree. AFFIRMED.

Shea M. Chapin of The Chapin Center, PLC, Dubuque, for appellant.

Brenna Bird, Attorney General, and David Banta, Assistant Attorney

General, for appellee.

Considered without oral argument en banc. 2

AHLERS, Judge.

In the early morning of June 19, 2023, a farm owner notified law

enforcement that a Chevrolet Captiva with Wisconsin license plates had crashed

into a tree at the caller’s residence. A short distance down the road from that

residence, a John Deere Gator utility vehicle was stolen from a second farm. The

Gator was found crashed at a third farm a few miles away. At the farm where the

Gator was crashed, a 2013 Chevrolet Impala was missing.

An investigation revealed that Dillon Heiller was driving the Captiva just

before it crashed at the first farm, and his blood was found on a bandana left in the

crashed Gator. The State charged Heiller with theft in the second degree for the

Captiva and theft in the first degree for the Gator. The jury found him guilty of both

crimes,1 and the district court sentenced him accordingly. Heiller appeals.

I. Territorial Jurisdiction—Theft of the Captiva

Heiller challenges his conviction for theft of the Captiva on the ground that

the State failed to prove he took possession of the vehicle in Iowa. He points out

that territorial jurisdiction is an essential element of a crime that the State is

required to prove beyond a reasonable doubt. See State v. Liggins, 524 N.W.2d

181, 184–85 (Iowa 1994). But, while Heiller attempts to frame the issue as a

challenge to the sufficiency of the evidence of territorial jurisdiction, the substance

of his argument is a complaint about the jury instructions. In particular, he

complains about this marshaling instruction given to the jury:

1 The State also charged Heiller with theft of the Impala and being a felon in possession of a handgun in the Impala. The jury found him not guilty of those crimes. As the issues on appeal do not involve those charges, we will not address them further. 3

The State must prove all the following elements of [second] degree theft: 1. On or about the 19th day of June, 2023, the defendant took possession or control of [a] 2012 silver Chevrolet Captiva. . . . 2. The defendant did so with the intent to deprive the owner of the 2012 silver Chevrolet Captiva. . . . 3. The property, at the time of the taking, belonged to or was in the possession of its owner.

Heiller argues that this marshaling instruction was erroneous because it “did

not require a finding that the offense was committed wholly or partly within the

State of Iowa.” Heiller argues that by failing to require the State to prove an

essential element of the offense beyond a reasonable doubt, the instruction

violated his constitutional due process rights.

But there are two interrelated problems for Heiller. First, jury instructions to

which no objection is lodged become the law of the case for purposes of a

sufficiency challenge. See State v. Schwartz, 7 N.W.3d 756, 764 (Iowa 2024).

Heiller made no substantive objection to the jury instructions, including the

marshaling instruction at issue, so they became the law of the case. As the

marshaling instruction contained no territorial-jurisdiction element, Heiller’s

attempts to make his territorial-jurisdiction argument a sufficiency challenge fail.

In substance, his territorial-jurisdiction challenge is to the failure of the

marshaling instruction to include a territorial-jurisdiction requirement. This leads

to Heiller’s second problem. To challenge a jury instruction, Heiller was required

to object to it to preserve error. See State v. Davis, 951 N.W.2d 8, 16 (Iowa 2020)

(“We have repeatedly held that timely objection to jury instructions in criminal

prosecutions is necessary in order to preserve any error thereon for appellate

review.” (quoting State v. Taggart, 430 N.W.2d 423, 425 (Iowa 1988))); see also 4

State v. Brammer, No 24-0127, 2025 WL 52854, at *6 (Iowa Ct. App. Jan. 9, 2025)

(requiring a defendant to object to a marshaling instruction related to territorial

jurisdiction to preserve error). And the fact that Heiller attempts to turn the claimed

faulty instruction into a constitutional issue does not help him because

constitutional objections also must be made to the district court to preserve error.

See State v. Tucker, 982 N.W.2d 645, 653 (Iowa 2022) (“Litigants may not raise

issues—including constitutional issues—for the first time in an appeal.”).

As Heiller made no objection to the marshaling instruction’s failure to

include a territorial-jurisdiction element, he has not preserved his substantive or

constitutional challenges to the instruction on appeal. We reject his territorial-

jurisdiction challenge accordingly.

The only way Heiller could avoid this outcome is if he could persuade us

that territorial jurisdiction is a question of subject matter jurisdiction. If it is, then

the challenge can be raised for the first time on appeal, even if Heiller never

presented the issue to the district court. See State v. Ambrose, 861 N.W.2d 550,

561 (Iowa 2015) (addressing an issue of subject matter jurisdiction on appeal even

though the issue was not raised below). And we would have to vacate Heiller’s

conviction because we cannot say that the jury found beyond a reasonable doubt

that the requirements of the territorial-jurisdiction statute were met here even if it

is possible the facts would support such a finding. See Liggins, 524 N.W.2d at

184–85 (finding territorial jurisdiction to be “an essential element of the crime” to

be “submitted at trial” and proved “beyond a reasonable doubt” unless “the

jurisdictional facts are undisputed”). 5

To answer the question of whether Heiller’s territorial-jurisdiction challenge

is one of subject matter jurisdiction, we look to our case law. Our court has

marginally weighed in on the topic. In State v. Bradley, we found territorial

jurisdiction to be a question of subject matter jurisdiction—at least in the context of

requiring a defendant to pay restitution related to a crime prosecuted in Missouri.

637 N.W.2d 206, 214 (Iowa Ct. App. 2001), abrogated on other grounds by State

v. Jenkins, 788 N.W.2d 640, 645–47 (Iowa 2010).

We are not aware of any Iowa Supreme Court case holding that territorial

jurisdiction is a question of subject matter jurisdiction. True, in State v. Rimmer,

the supreme court said, “Challenges to territorial jurisdiction, which go to the power

of the court to hear the case, cannot be waived.” 877 N.W.2d 652, 663 (Iowa

2016). But this quoted passage says nothing about subject matter jurisdiction—

nor does any other part of the Rimmer opinion. Further, the quoted passage is

dicta. It is a single sentence, buried in paragraphs cataloging the difference
