Langholz, JJ. 2
SCHUMACHER, Presiding Judge.
Scott Swartz appeals the following issues: (1) a finding that Swartz was not
legally insane at the time of the offenses; (2) a finding that Swartz acted with malice
aforethought; and (3) the imposition of consecutive sentences.

I. Background Facts & Proceedings
Marshalltown law enforcement received a mid-afternoon call from Vicki
Gunter, who is Swartz’s mother and the victim’s ex-wife. The victim, Paul, was
Swartz’s father.1 Vicki reported that Swartz told her over the phone that his dad
had been on the ground for a couple of hours. Vicki “knew immediately that
something wasn’t right” because Swartz’s “words were very erratic and irrational
and bizarre.” Swartz, in his late forties, had been living with his father. The phone
call between Swartz and his mother lasted for about forty-five minutes. Vicki also
stated that Swartz had been released from Allen Memorial Hospital recently and
Swartz told her there was a loaded shotgun in the house. Vicki later testified that
she called law enforcement because she was concerned about Swartz’s
statements, including that Paul had fallen down some stairs and tripped on a gun
case.
1 The appellant and his father share a surname. So, for purpose of this opinion we refer to the parents by their first names and the appellant by his surname. 3
Based on Vicki’s call, law enforcement was dispatched to Paul’s home to
perform a welfare check. Swartz voluntarily allowed two officers to enter. As
Swartz was guiding one of the officers inside, he stated, “He’s been laying there
since 11:30. He’s a piece of shit. He’s Saul. He’s garbage. He’s one demented
fuck.” Paul was found lying on the bathroom floor covered in blood, using his finger
to point toward his face and then at Swartz. No one else was found within the
residence.
One officer directed Swartz away from Paul. While requesting that Swartz
sit on a couch, Swartz complained to law enforcement about Paul’s television
preferences, “. . . every day, its fucking death . . . .” Before sitting down, Swartz
gestured toward a shotgun on the couch, grabbed it, and stated, “this is what I
found . . . I lost it at the pawn shop, he tracked it, the shell fell out of it, its fully
loaded . . . .” The officer tried to unload the gun, found a shell jammed in the
chamber that he could not remove, and placed it on the kitchen table. Another
officer disassembled the gun but still could not remove the jammed shell. Swartz
was then searched, and another shotgun shell and Paul’s inhaler were found in his
pocket.
Swartz, when speaking to the officers, stated he shoved Paul twice. He
also stated that Paul “ran into the door” and “crawled back into the bathroom” and
had been lying in the bathroom since 11:30 a.m. Swartz went on to describe the
phone conversation with Vicki where she said he should help Paul, and Swartz
had hung up on her, stating to officers “[T]hat’s the stupidest shit you can say . . . .”
Swartz rambled continuously while in the residence, in the law enforcement
vehicle, and while at the police station. 4
Although Swartz had blood on his shoes and pant leg, he had no observable
injuries and stated to law enforcement that he had no injuries. Swartz cooperated
with law enforcement at the residence. He was handcuffed, walked out to a law
enforcement vehicle, and transported to the police station.
During the transport, Swartz continued to talk. Video evidence from within
the vehicle showed him referring to Paul in a negative manner: “he’s so fucking
sick”; “he’s not even worth saving”; “you guys are gonna actually try to save that
fucking piece of shit, there’s nothing fucking wrong with him, oh my god, and you’re
gonna fucking rescue him, fuck I’ll come back and kill him myself, it took fucking
two shoves”; “he’s trash.” The subject of his rambling then turned to his mother,
stating, “my mom obviously called you guys, she’s the only one that could have”;
“my fucking mom’s garbage.” He continued, “I’ve been awake since 5 o’clock in
the morning, woke up to seven hours of epiphanies”; “I only shoved him twice,
there’s no reason why he can’t get up, he hit the ground by the stairs, and crawled
back into the bathroom, it’s the biggest stain in there, I cleaned it three times, that’s
how he wants to be remembered.”
After arriving at the police station, Swartz stated that he “used a gram, but
still wasn’t feeling anything from it.” A detective attempted to interview Swartz
later, who was uncooperative, and after the detective left the room, Swartz
upended a table and damaged a telephone.
Back at the residence, another law enforcement officer waited with Paul
until paramedics arrived. Paul was then transported to Unity Point Hospital, where
photographs of his injuries were taken. He was later transferred to University of
Iowa Hospital. Paul’s injuries included extensive bruising on his arms, torso, and 5
head, a fractured femur, a laceration on his scalp, fractured facial bones, blood in
the chest cavity, and a fractured rib. Paul subsequently died while at University of
Iowa Hospital. An autopsy was performed revealing the extent of his injuries. The
forensic pathologist who completed the autopsy testified that while the injuries may
not have been independently fatal, they might, together, “produce enough
physiologic stress, enough stress on [his] body, that results in death, particularly
when there are other underlying medical conditions at play.” Paul had heart
disease, high blood pressure, hypertension, coronary artery atherosclerosis, renal
disease, and pulmonary emphysema.
Officers had noticed extensive property damage within the residence
including a fan that was knocked over in Paul’s bedroom, a hole in the drywall
immediately outside Paul’s bedroom, a broken picture frame on the floor, and
damage to Paul’s bedroom door and frame. The strike plate and screws to Paul’s
bedroom door latch were lying on the floor. There were copious amounts of blood
within the bathroom where Paul was located.
After obtaining a warrant to search the home, detectives seized evidence
from Swartz’s bedroom including a plastic bag with a crystalline substance in it,
straws with white residue, and a glass pipe. The shotgun that Swartz showed to
the initial responders was seized and sent for DNA testing, as law enforcement
noticed a red substance on the stock of the gun. Buccal swabs were then taken
pursuant to a warrant from Swartz and Paul’s autopsy, which were later submitted
for analysis.
The crystalline substance recovered from Swartz’s bedroom tested positive
for methamphetamine. The criminalist who performed testing on the red 6
substance located on the stock of the shotgun determined it matched Paul’s DNA
profile. The “rough areas” of the gun were swabbed and tested and also tested for
touch-transfer DNA. The results showed a mixture of three people, with the “major
contributor” being Swartz.
Swartz was charged via amended and substituted trial information with first-
degree murder, in violation of Iowa Code sections 707.2(1)(a) and 707.1 (2023);
prohibited person in possession of a firearm, in violation of sections 724.26, 902.8,
and 902.9(1)(c); prohibited person in possession of ammunition, in violation of
sections 724.26, 902.8, and 902.9(1)(c); possession of a controlled substance,
second offense, in violation of sections 124.206 and 124.401(5); and fourth-degree
criminal mischief, in violation of sections 716.1, 716.2, and 716.6. Swartz entered
a plea of not guilty to all these charges.
Swartz waived his right to a jury trial and filed a notice of intent to rely on
defenses of insanity or diminished capacity. Following a bench trial, Swartz was
convicted of second-degree murder, prohibited person in possession of a firearm,
prohibited person in possession of ammunition, and possession of a controlled
substance.2
The district court sentenced Swartz on the murder conviction to fifty years
of incarceration, with a seventy-percent mandatory minimum. As to both the
prohibited-persons convictions, Swartz received sentences of fifteen years of
incarceration, with three-year mandatory minimums. And for the possession-of-a-
controlled-substance conviction, he was sentenced to two years of incarceration.
2 Swartz was convicted as a habitual offender on the possession of a firearm and
ammunition charges. 7
The sentences were ordered to be served consecutively for a total of eighty-two
years, subject to mandatory applicable minimums.
II. Discussion
a. Insanity Defense
Swartz asserts the trial court’s rejection of his insanity defense was in error.
The court held Swartz failed to prove “by preponderance of evidence that he met
the necessary elements to establish the complete defense of insanity.” But the
court found that Swartz “was unable to form the specific intent . . . required by law
due to his diminished capacity” based on his ingestion of methamphetamine before
he attacked Paul. Swartz disputes the insanity determination, arguing there was
substantial evidence demonstrating his insanity because of expert testimony
concluding he was insane during the incident.
The trial court employed Uniform Jury Instruction 700.1 to determine
whether Swartz was guilty of murder in the first-degree:
1. On or about January 7, 2023, the Defendant struck [Paul]. 2. [Paul] died as a result of being struck. 3. The Defendant acted with malice aforethought. 4. The Defendant acted willfully, deliberately, premeditatedly, and with specific intent to kill [Paul]. 5. These events occurred in the County of Marshall in the State of Iowa.
We review challenges to the sufficiency of the evidence “for correction of
errors at law and will uphold the [factfinder]’s verdict if it is supported by substantial
evidence.” State v. Kieffer, 17 N.W.3d 651, 655 (Iowa 2025). Evidence is
considered substantial if it is sufficient to “convince a rational fact finder the
defendant is guilty beyond a reasonable doubt.” Id. (quoting State v. Crawford,
974 N.W.2d 510, 516 (Iowa 2022)). “[W]e view the evidence ‘in the light most 8
favorable to the State, including all reasonable inferences that may be fairly drawn
from the evidence.’” Id. (quoting State v. Sanford, 814 N.W.2d 611, 615 (Iowa
2012)).
Iowa Code section 701.4 defines the defense of insanity in criminal cases:
A person shall not be convicted of a crime if at the time the crime is committed the person suffers from such a diseased or deranged condition of the mind as to render the person incapable of knowing the nature and quality of the act the person is committing or incapable of distinguishing between right and wrong in relation to that act. Insanity need not exist for any specific length of time before or after the commission of the alleged criminal act. If the defense of insanity is raised, the defendant must prove by a preponderance of the evidence that the defendant at the time of the crime suffered from such a deranged condition of the mind as to render the defendant incapable of knowing the nature and quality of the act the defendant was committing or was incapable of distinguishing between right and wrong in relation to the act.
The State and Swartz presented competing expert testimony regarding
whether Swartz was insane before, during, or after the incident with his father. The
defense expert, Dr. Rosell, testified that Swartz experienced psychosis
independent of drug use, and his behavior on the day of the incident indicated
psychosis, which showed Swartz was unable to distinguish between right and
wrong. Dr. Rosell also testified that Swartz was diagnosed with schizophrenia in
2012.
Dr. Jones-Thurman first testified that Swartz’s schizophrenia diagnosis was
incorrect, as the diagnosis came later in his life, which is abnormal. Dr. Jones-
Thurman instead diagnosed Swartz with antisocial personality disorder and
unspecified mood disorder, and he attributed Swartz’s behavior on the day of the
incident to drug-induced psychosis. But when Dr. Jones-Thurman was confronted
with cross-examination as to whether she properly diagnosed Swartz with 9
antisocial personality disorder because he did not show symptoms before age
fifteen, she admitted there was not any evidence of early onset symptoms, which
was a nondiscretionary criterion for the diagnosis.
The trial court concluded that Swartz did not prove a defense of insanity.
The district court also found Swartz was unable to form specific intent required for
first-degree murder as he suffered from diminished capacity due to drug use and
therefore was guilty of second-degree murder.
Swartz argues Dr. Jones-Thurman provided an opinion which was “so
impossible, absurd, and self-contradictory that the court should [have] deem[ed] it
a nullity.” See State v. Cahill, 972 N.W.2d 19, 33 (Iowa 2022) (citation omitted).
When there is conflicting testimony regarding insanity, “the issue of sanity is clearly
for the fact finder to decide.” State v. Jacobs, 607 N.W.2d 679, 685 (Iowa 2000);
State v. Stowe, No. 21-0080, 2022 WL 2826025, at *3 (Iowa Ct. App.
July 20, 2022). “The trial court as trier of fact is not obligated to accept opinion
evidence, even from experts, as conclusive.” Jacobs, 607 N.W.2d at 685. When
the trial court must make determinations based upon “a battle of experts, we, as
the reviewing court, readily defer to the district court’s judgment as it is in a better
position to weigh the credibility of the witnesses.” Id. While we afford the trial court
deference in expert opinion credibility determinations, the testimony “should not be
arbitrarily and capriciously rejected.” Stowe, 2022 WL 2826025, at *1 (citation
omitted).
Here, the trial court found that each expert provided credible reasons for
their differing opinions. The court did not determine that Dr. Jones-Thurman’s
antisocial personality diagnosis contradiction during cross-examination “stole very 10
much from [the witness’s] professionalism and credibility.” The court’s conclusion
that Swartz was sane at the time of the incident but suffered from diminished
capacity “is supported by the State’s expert’s testimony and additional evidence
supporting the expert’s conclusions.” See State v. Belk, No. 21-1742, 2022 WL
10861390, at *2 (Iowa Ct. App. Oct. 19, 2022).
As the district court found, the supporting evidence includes the fact that
Swartz’s mental condition stabilized “when he was treated at Allen Hospital prior
to this incident, as well as after he was taken into custody and stabilized at Marshall
County Jail.” We agree with the district court’s assessment that the evidence
showed Swartz’s condition improved “when he return[ed] to being treated for his
underlying mental health condition(s) and [did] not have access to illegal drugs.”
See id. at *3. The court found that Swartz “undisputedly suffered from long-
standing cannabis and amphetamine disorders, and these disorders have
impacted his underlying mental health condition[s].”
Although Swartz indeed suffers from underlying mental-health conditions,
they “do[] not meet the definition of insanity under Iowa law.” The court determined
that when these conditions are untreated and combined with methamphetamine
usage, Swartz has a lessened ability to form specific intent. The court found
Swartz possessed diminished responsibility due to his methamphetamine usage
on or immediately before the incident. See State v. Hall, 214 N.W.2d 205, 207
(Iowa 1974) (noting temporary mental conditions caused by voluntary intoxication
“do[] not constitute a complete defense”).
Viewing the evidence in light favorable to the State, and applying deference
to the trial court’s factual determinations, we find sufficient evidence supports that 11
Swartz failed to prove he was insane before, during, or after the incident. See
Kieffer, 17 N.W.3d at 655; Belk, 2022 WL 10861390, at *3.
b. Malice Aforethought
Swartz asserts there was insufficient evidence showing he possessed
malice aforethought as required for a conviction of second-degree murder as it is
speculative that Swartz used the shotgun to inflict blunt-force injuries and that his
statements indicating malice were the product of a muddled mind. See Iowa Code
§ 707.1. We review sufficiency-of-the-evidence challenges for correction of errors
at law. Kieffer, 17 N.W.3d at 655.
Malice aforethought is a phrase “used to describe a culpable state of mind,
an essential element of the offense of murder that the state must prove . . . beyond
a reasonable doubt.” State v. Green, 896 N.W.2d 770, 780 (Iowa 2017). Malice
is a state of mind “which prompts one to do a wrongful act intentionally, without
legal justification or excuse.” Id. at 779 (citation omitted). “Malice aforethought
may accompany an unlawful intent to kill, or may simply be an unlawful intent ‘to
do physical harm to another’ that results in death.” Id. (quoting State v. Myers, 653
N.W.2d 574, 579 (Iowa 2002)). This state of mind applies both to “a specific intent
to kill or . . . the general intent to do physical harm . . . .” Id. A factfinder may infer
malice aforethought because of employment of a dangerous weapon. Id. at 780.
A “dangerous weapon” is statutorily defined as
any instrument or device designed primarily for use in inflicting death or injury upon a human being or animal, and which is capable of inflicting death upon a human being when used in the manner for which it was designed, except a bow and arrow when possessed and used for hunting or any other lawful purpose. Additionally, any instrument or device of any sort whatsoever which is actually used in such a manner as to indicate that the defendant intends to inflict 12
death or serious injury upon the other, and which, when so used, is capable of inflicting death upon a human being, is a dangerous weapon. Dangerous weapons include but are not limited to any offensive weapon, pistol, revolver, or other firearm, dagger, razor, stiletto, switchblade knife, knife having a blade exceeding five inches in length, or any portable device or weapon directing an electric current, impulse, wave, or beam that produces a high-voltage pulse designed to immobilize a person.
Iowa Code § 702.7. This inference exists because a rational factfinder “could infer
that one who uses a dangerous weapon intends to cause physical harm, and even
to kill.” Green, 896 N.W.2d at 780. A dangerous weapon can include “almost any
instrumentality under certain circumstances.” State v. Ortiz, 789 N.W.2d 761, 767
(Iowa 2010) (citation omitted).
Here, the trial court concluded that Swartz struck his father with the stock
of the shotgun, implicating the dangerous weapon inference. Swartz argues the
“dangerous weapon inference is inapplicable because it is sheer speculation to
conclude Swartz struck Paul with the shotgun, and . . . it is speculation to conclude
Swartz intended death or grievous bodily harm by doing so.”
Contrary to Swartz’s claim, the evidence shows that Paul’s DNA profile was
present within the blood found on the stock. Also, DNA testing on the “rough
areas,” where a person would normally hold the shotgun, showed Swartz as the
primary contributor of DNA among two other profiles. A factfinder could reasonably
infer that the DNA evidence demonstrates that Swartz held the shotgun and hit his
father with the stock, causing blunt-force injuries. See State v. Walden,
No. 18-0209, 2019 WL 6358300, at *8 (Iowa Ct. App. Nov. 27, 2019).
Swartz also asserts that even if he struck his father with the stock of the
shotgun, the usage was not within the statutory definition because it was “not used 13
in the manner for which it was designed.” See Iowa Code § 702.7. Swartz’s
argument is that using a “rubber-capped butt of the shotgun” to hit someone does
not indicate malice because it is not foreseeable that death or bodily harm could
arise from using the gun in that manner. See Green, 896 N.W.2d at 780. But this
argument ignores the statute’s text, which states “any instrument or device . . .
which is actually used in such a manner as to indicate that the defendant intends
to inflict death or serious injury upon the other, and which, when so used, is
capable of inflicting death upon a human being, is a dangerous weapon.” Iowa
Code § 702.7.
A reasonable factfinder could, based on DNA evidence, infer that Swartz
used the shotgun to strike his father with the intention to inflict death or serious
injury, demonstrating malice aforethought. See Walden, 2019 WL 6358300, at *8;
see also State v. Linderman, 958 N.W.2d 211, 222 (Iowa Ct. App. 2021) (observing
a severe beating can serve as an inference of malice aforethought).
Swartz further asserts that because of his diminished capacity, the trial court
erred in finding malice through the statements he made regarding his father.
“Evidence of bad feelings or quarrels between the defendant and the victim are
circumstances that may be used to support a finding of malice aforethought.” State
v. Buenaventura, 660 N.W.2d 38, 49 (Iowa 2003); accord State v. Thompson, 982
N.W.2d 116, 122 (Iowa 2022). Malice aforethought need not exist “for any
particular length of time.” Buenaventura, 660 N.W.2d at 49 (citation omitted). “The
State may show premeditation ‘by the nature of the crime and the defendant’s
actions afterwards.’” State v. Tate, No. 11-1671, 2013 WL 261248, at *5 (Iowa Ct.
App. Jan. 24, 2013) (quoting Buenaventura, 660 N.W.2d at 49). 14
Here, there is ample evidence of bad animosity between Swartz and his
father, which supports the finding of malice. See Thompson, 982 N.W.2d at 122
(providing examples of strained relationships in connection with malice
inferences). The evidence demonstrates Swartz’s ill feelings towards his father.
Swartz made statements including that the police should not bother to save his
father, that Swartz would “kill him off,” and referred to his father repeatedly as a
“piece of shit,” “trash,” and “demented.”
And the evidence shows Swartz left his father struggling and injured on the
bathroom floor for upwards of four hours without calling for help before law
enforcement arrived at the prompting of Vicki. A reasonable factfinder could infer
the existence of malice through Swartz’s statements and actions after the incident.
See Buenaventura, 660 N.W.2d at 49.
We find the trial court did not err in determining the existence of malice
aforethought due to substantial evidence showing Swartz used a dangerous
weapon and possessed ill will toward his father.
c. Sentencing
Swartz asserts the trial court abused its sentencing discretion by ordering
all the sentences to run consecutively based on the nature of one offense and the
separate nature of the other offenses.
We review challenges to sentencing for abuse of discretion. State v. West
Vangen, 975 N.W.2d 344, 355 (Iowa 2022). “A court abuses its discretion when it
relies on impermissible factors to sentence a defendant.” Id. Sentencing decisions
by a trial court “to impose a particular sentence within the statutory limits is cloaked
with a strong presumption in its favor . . . .” State v. Formaro, 638 N.W.2d 720, 15
724 (Iowa 2002). “An abuse of discretion will not be found unless we are able to
discern that the decision was exercised on grounds or for reasons that were clearly
untenable or unreasonable.” Id.
Swartz claims that the trial court abused its sentencing discretion for two
reasons; first, that the court should not have imposed consecutive sentences for
each count because they are separate and distinct within themselves, and second,
that the nature of one offense is not a valid reason to impose consecutive
sentences on the other offenses.
Iowa Code section 901.8 allows a sentencing judge to impose consecutive
sentences if there are two or more separate offenses, even if the “offenses were
committed in the course of a single transaction.” State v. Criswell, 242 N.W.2d
259, 260–61 (Iowa 1976) (citation omitted); accord State v. Olson, No. 22-1305,
2023 WL 5092217, at *3 (Iowa Ct. App. Aug. 9, 2023). Sentencing courts are
required to “explicitly state the reasons for imposing a consecutive sentence,
although in doing so the court may rely on the same reasons for imposing a
sentence of incarceration.” State v. Hill, 878 N.W.2d 269, 275 (Iowa 2016).
The trial court’s sentencing order states the reasons for the imposition of
consecutive sentences: “the separate, serious nature of murder in Count I;
Defendant’s marked lack of remorse; the Defendant’s extensive criminal history
which includes prior convictions for violent behavior and controlled substance
violations; and the separate and distinct nature of each of these offenses.”
Because the sentencing court stated its reasoning for imposing consecutive
sentences based on appropriate factors, we affirm. 16
III. Conclusion
For the above reasons, we affirm.
