GOODHUE, Senior Judge.

John David Green appeals his conviction of murder in the second degree

following a jury trial. 

I. Background Facts and Proceeding.

Mark Koster moved to Sac City and purchased a house there sometime 

between 1999 and 2000. In July 2009, Koster’s mailbox was discovered filled 

with unopened mail, and his utility bills had not been paid for some time. When 

Sac City Police Chief John Thomsen checked on Koster’s welfare, he found the 

house locked and a note on the door stating, “[G]one to Florida with Tom for the 

winter. See you in the spring, Mark.” The note gave a telephone number of a 

resort in Florida, which Chief Thomsen called, but the resort had no record of 

Koster. 

Koster did not return in the spring. In May 2010, Koster was listed as a 

missing person, and a search warrant for the house was obtained. Koster’s car 

was in the garage, the house was in order and tidy, the refrigerator was empty, 

and the dresser was full of clothes, but Koster was nowhere to be found. 

Koster’s family filed a petition to have him declared dead, and the house was 

sold to Wesley Galeson. In November 2012, Galeson was cleaning the 

basement when he discovered a body under a pile of rubbish and kitty litter.

Chief Thomsen and Assistant Chief Mark Jansma investigated and discovered a 

mummified body wrapped in a blanket. Dental x-rays were used to identify the 

body as Koster. An autopsy revealed the hyoid bone (neck bone) and thyroid 

cartilage (Adam’s apple) were fractured. A criminologist from the Iowa Division
3

of Criminal Investigation searched the scene for forensic evidence, but no 

identifiable fingerprints or DNA was recovered. 

Sandra Dierenfeld, a neighbor of Koster, advised the authorities that a few 

weeks before he disappeared, Koster had been living with a man she had known 

only as Tom, as well as Tom’s dog. The authorities discovered Koster had a 

friend by the name of Thomas Falke, who was living in Kansas City. Officers 

went to Kansas City to interview him, but Falke’s employment records indicated 

he could not have been living in Iowa in the spring and early summer of 2009. 

Falke identified John David Green as someone they should talk to. 

Pictures of Green and his dog were obtained. Dierenfeld thought the 

pictures showed the man that had been living with Koster in 2009-2010, and she 

was more certain the pictures of the dog showed the dog she had seen at 

Koster’s home. After locating Green in Florida, authorities—including Sac 

County Attorney Ben Smith—traveled there to question him. The Iowa 

authorities, accompanied by Florida law enforcement, went to the camper Green 

was living in with his dog. Green then voluntarily went to the local sheriff’s office 

for an interview. Although Green was not advised of his Miranda rights, the door 

to the interview room was unlocked, Green was told he could leave at any time, 

and the interview was not confrontational.

In the interview Green initially denied he had been in Iowa, but he

eventually admitted he had been living with Koster in Sac City. He stated he had 

known Koster since 1985, and they had periodically worked together and lived in 

the same residence. The version of events he gave in the interview and later in 

his trial testimony were substantially consistent: Green and Koster were living at 
4

Koster’s home in Sac City in the early summer of 2009. Koster had become 

confrontational and was particularly upset with his father. Koster had attacked 

Green with a baseball bat. The two fell to the floor, and Green held the bat 

against Koster’s throat until he died. Green took Koster’s wallet containing fiftysix dollars and his identification, and took Koster’s body to the basement where 

he covered it with kitty litter and other debris. He tidied up the house, wrote the 

note that he attached to the door, and left. Green claimed he failed to report 

Koster’s death to law enforcement because he knew no one in the area and 

assumed his claim that he had acted in self-defense would not be believed. 

During Green’s interview, the police chief and assistant chief intermittently 

consulted with the Sac County Attorney, who audited the interview from another 

room. After the interview, Green was taken back to his camper by an officer. 

Green consented to the search of the camper, but nothing incriminating was 

found. The officers were notified charges were going to be filed, and accordingly,

Green was placed under arrest and was charged with first-degree murder. The 

medical examiner reevaluated Koster’s remains and determined that his death 

was caused by strangulation consistent with a straight, hard object being pressed 

against his neck. 

Green filed a motion to suppress the Florida interview under the Sixth 

Amendment of the United States Constitution and article 1, section 10 of the 

Iowa Constitution. The motion expressly put forth the contention that the right to 

counsel attached when the prosecutorial forces focused on him. The trial court’s 

ruling and counsel’s arguments centered on custody or other deprivation of 

freedom of action as the triggering event of the right to counsel under the Fifth 
5

Amendment. The motion was denied, and the results of the Florida interview 

were admitted into evidence. 

At trial, Green argued he acted in self-defense. The jury found him guilty

of murder in the second degree, and he was sentenced to confinement for an 

indeterminate term of no more than fifty years. Green filed a timely notice of 

appeal.

II. Attachment of Right to Counsel.

Green first contends the trial court erred in denying his motion to suppress 

the statements he made during his interview in Florida because he was the 

primary subject of prosecutorial focus at the time of the interview. He argues that 

his right to counsel was triggered by the prosecutorial focus and apparently 

contends that law enforcement had an obligation to advise him of his right to 

counsel, which they failed to do. 

A. Error Preservation

Generally, the denial of a motion to suppress is adequate to preserve error

as to the issue raised in the motion. State v. Lovig, 675 N.W.2d 557, 562 (Iowa 

2004). The State concedes Green raised the violation of the Sixth Amendment 

to the United States Constitution in his motion to suppress but contends Green 

did not raise, and the trial court did not rule on, the applicability of article 1,

section 10 of the Iowa Constitution. 

When there are parallel constitutional provisions in the federal and state 

constitutions and a party does not indicate the specific constitutional violation of 

both constitutions, we generally regard both claims to be preserved. King v. 

State, 797 N.W.2d 565, 571 (Iowa 2011). Furthermore, in his written motion to 
6

suppress, Green specifically referred to article 1, section 10 of the Iowa 

Constitution and the right to counsel as it relates to situations where prosecutorial 

forces are focused on a particular defendant. Error has been preserved.

B. Standard of Review

When constitutional issues are involved, our review is de novo. State v. 

Tyler, 867 N.W.2d 136, 152 (Iowa 2015). We give deference to the trial court’s 

findings, though we are not bound by them. Id. at 153. 

C. Discussion

The trial court’s ruling denying the motion to suppress was primarily 

concerned with the Fifth Amendment rights implicated by Green’s interview. That 

issue is not raised in this appeal. The trial court also addressed the Sixth 

Amendment rights and article 1, section 10 rights by noting that the right to 

counsel attaches at the time adversarial judicial criminal proceedings are initiated 

against the persons, whether by way of formal charge, arraignment, preliminary 

hearing, information, or indictment, citing State v. Jackson, 380 N.W.2d 420, 423

(Iowa 1986). Green agrees that Jackson is a correct statement of what is 

necessary to trigger one’s right to counsel under the Sixth Amendment. 

However, he contends that article 1, section 10 of the Iowa Constitution triggers 

the right to counsel when the prosecution becomes so heavily involved in the 

case that the accused is confronted by an expert adversary. Green cites no 

direct authority for his contention. 

Green claims that once an accused asserts his right to counsel, the 

guarantee of article 1, section 10 becomes applicable and that further 

uncounseled statements are inadmissible unless the accused initiated further 
7

conversation, and knowingly and intelligently waived the right to counsel. See 

State v. Newsom, 414 N.W.2d 354, 359 (Iowa 1987). At no point, however, did 

Green assert his right to counsel during or prior to the interview. Green is correct 

in asserting that the filing of an indictment or trial information is the 

commencement of a felony charge in Iowa. He is also correct that our supreme 

court has held the right to counsel may attach at a time prior to the filing of a trial 

information or indictment when a complaint has been filed, a warrant issued, and 

an arrest made. See Jackson, 380 N.W.2d at 423-24; State v. Johnson, 318 

N.W.2d 417, 434-35 (Iowa 1982). Nothing in either Jackson or Johnson

indicates the right to counsel attaches under Iowa law on the basis of 

prosecutorial focus and involvement absent some formal, objective action by law 

enforcement to indicate the results of an investigation support a criminal charge. 

We are not constrained to interpret parallel components of the Iowa 

Constitution and the Federal Constitution in the same manner as interpreted by 

the federal courts, but we can consider the persuasiveness of the federal court’s 

position. State v. Young, 863 N.W.2d 249, 257 (Iowa 2015). The words “in all 

criminal prosecutions and involving the life or liberty of an individual” are words 

contained in article 1, section 10 of the Iowa Constitution that do not appear the 

Sixth Amendment of the United States Constitution. The language cited is the 

critical difference that creates a right to counsel in a misdemeanor case, while no 

such right exists under the Sixth Amendment. See id. The additional language 

does not accelerate the attachment of the right to counsel in the manner Green 

alleges. A criminal “prosecution” does not exist at the investigatory stage. Green 

has cited no precedent for accelerating the right to counsel or the existence of a 
8

“prosecution” at the pre-complaint, pre-arrest, or pre-custody stage of an

investigation.

We affirm the denial of Green’s motion to suppress.

III. Claim of Erroneous Instructions.

Green also challenges two of the jury instructions. Over his objections,

the jury was instructed as follows: 

Instruction No. 19

If a person has the opportunity to deliberate and uses a 

dangerous weapon against another resulting in death you may but 

are not required to infer that the weapon was used with malice, 

malice aforethought, premeditation, and specific intent to kill.

Instruction No. 20

A dangerous weapon is any sort of instrument or device 

which is actually used in such a way as to indicate the user 

intended to inflict death or serious injury and when so used is 

capable of inflicting death.

Green contends that the combination of these two instructions erroneously 

permitted the jury to find malice based on the use of a dangerous weapon,

regardless of whether the facts supported such a finding. According to Green, 

doing so allowed the jury to find malice aforethought “without proof beyond a 

reasonable doubt,” in violation of the Fourteenth Amendment of the United States 

Constitution and article 1, section 19 of the Iowa Constitution.

A. Error Preservation

Green specifically cites to State v. Ambrose, 861 N.W.2d 550 (Iowa 2015),

in challenging the jury instruction, emphasizing the fact that Koster brought the 

alleged dangerous weapon to the fracas rather than him. In Ambrose, our 

supreme court recited a hypothetical situation very similar to the facts as alleged 
9

by Green and cautioned that care should be used in instructing the jury on the 

malice inference. 861 N.W.2d at 560. As in Ambrose, Green argues the 

inference instruction amounted to an unfair comment on the evidence by the 

court. See id. Given the reference to Ambrose and the hypothetical it used, the 

court and the State were adequately put on notice of Green’s objection to the 

inference instruction and the reasons for the objection. 

Green also alleged ineffective assistance of counsel, which is an 

exception to the ordinary rules of error preservation. Id. at 555. We believe,

however, error was preserved, independent of the claim of ineffective assistance 

of counsel.

B. Standard of Review

Challenges to jury instructions are reviewed for corrections of law. State 

v. Heemstra, 721 N.W.2d 549, 553 (Iowa 2006). To the extent constitutional 

grounds are involved, our review is de novo. Id. Green objects to allowing the 

jury to infer malice aforethought by the use of a deadly weapon. 

C. Discussion

Green relies almost exclusively on the language contained in Ambrose, a 

first-degree-murder case in which the court used inference instructions similar 

the ones at issue. 861 N.W.2d at 554. In reviewing the propriety of instructing 

the jury on malice inference in that case, the supreme court discussed the 

following hypothetical situation: 

A is involved in a fight with B. A is winning the fight and has 

knocked B to the ground. B picks up a rock and strikes A. A dies 

as a result of being struck with the rock. B is charged with murder. 

The rock is argued to be a dangerous weapon because it is an 

instrument which is used in a manner as to indicate the defendant 
10

intends to inflict death or serious injury and is capable of inflicting 

death or serious injury. Using the inference instruction the 

prosecution is free to argue and the jury to conclude that B was 

acting with “malice aforethought” even though there is no evidence 

of spite, hatred, or ill will. 

Id. at 560 (quoting 4 Robert R. Rigg, Iowa Practice Series Criminal Law § 3:5 at 

87-88 (2014-2015 ed.)). The court noted,

Under this illustration, if an instrumentality used to cause death 

would not normally be used to cause death and the jury is 

instructed it can infer malice from the use of the instrument, the jury 

could draw an inference from the mere use of the instrument even 

though the actual surrounding evidence would not otherwise 

support malice. Thus, the instruction could be used by the jury as a 

substitute for a finding of malice based on the evidence. 

Id. (citation omitted).

The facts before the court in Ambrose differed from the above 

hypothetical. In Ambrose, the defendant had “entered the house in violation of a 

no-contact order, and he was armed with a baseball bat and a pistol, which he 

repeatedly fired at occupants in the house, as well as one occupant outside the 

house who was attempting to run from the dwelling.” Id. Under those 

circumstances, the trial court was justified in giving the inference instructions, 

which “did not present a danger that the jury could infer malice from underlying 

acts identified in the instruction that would not otherwise support the inference.” 

Id. However, because a jury could make an inference of malice without support 

from the surrounding evidence in the hypothetical, the court advised that “the use 

of inference instructions generate concerns that must be carefully considered in 

each case.” Id.

Green correctly argues his case is substantially similar to the Ambrose

hypothetical—though we note there is no evidence Koster was winning the fight,
11

there is evidence Green was much larger than Koster, and there is evidence that 

Koster was not in good health. We also agree the Ambrose court’s discussion of 

that hypothetical deserves respect and consideration. However, though there is 

some indication that inference instructions may be improper in some scenarios,

the commentary cited did not affect the result in Ambrose. We have no 

controlling precedent to adhere to since, to date, our supreme court has yet to 

find an inference instruction improper under an existing fact pattern rather than 

one hypothetically posed. In contrast to the dicta Green relies on in Ambrose, we 

are confronted with clear, controlling authority that requires us to affirm the use of

an inference instruction here. As the Ambrose court noted, 

We have permitted the practice of instructing juries on inferences of 

malice from certain evidence since 1858.[1] See State v. Gillick, 7 

Iowa 287, 311 (1858) (“Malice is legitimately inferred from the 

weapon used and where the killing is with a dangerous weapon 

calculated to produce and actually producing death in the absence 

of proof that it was accidental or upon provocation the presumption 

of law is that the act is voluntary and with malice aforethought”). 

Inferences are a part of our law and the practice of identifying 

specific inferences that may be drawn from general categories of 

evidence gives the jury an important focal point and tightens the 

analysis to eliminate inferences not supported by the evidence.

Id. at 560-61 (citation omitted).

 

1 The uniform inference instruction set out in Instruction No. 19 formerly included a 

caveat stating that the inference existed “in the absence of evidence to the contrary.” 

State v. Jeffries, 313 N.W.2d 508, 509 (Iowa 1981). The Jeffries court held the added 

language to be surplusage. Id. at 510. There is little discussion of the issue in Jeffries,

but self-defense was a claim in Jeffries, and the Jeffries court apparently considered the 

added language redundant because of the State’s obligation to prove an absence of 

self-defense. Id. at 509-10. The jury here was also instructed it was the State’s burden 

burden to prove Green’s acts were not justified by self-defense. When the jury returned 

a verdict of guilty to second-degree murder, the issue of justification was negated. 

There was no contention the victim’s death was an accident, and the jury was also 

instructed it was the State’s burden to prove intent.
12

The inference of malice arises simply “from the intentional use of a deadly 

weapon in a deadly manner.” State v. Reeves, 636 N.W.2d 22, 25 (Iowa 2001). 

A baseball bat qualifies as a dangerous weapon. See State v. Hill, 140 N.W.2d 

731, 734 (Iowa 1966) (“It has been said, and we agree, that the character of a 

dangerous weapon attaches by adoption when the instrument is applied or is 

carried for use against another in furtherance of an assault.”). It was used here 

in a deadly manner. Furthermore, malice may be implied. See Iowa Code 

§ 707.1 (2011). The jury was told in Instruction No. 21 that malice “may be found 

from the acts and conduct of the defendant, and the means used in doing the 

wrongful and injurious act.”2 The acts and conduct of Green, without more, are 

adequate for a jury to find malice under Iowa law. See State v. Lee, 494 N.W.2d

706, 707-08 (Iowa 1993). The jury so found when it returned a verdict of guilty 

on the second-degree-murder charge.

There is no authority for the proposition that use of a weapon provided by 

the victim as a weapon of opportunity by the perpetrator—rather than its use as a 

weapon of choice provided by the perpetrator—invalidates the inference 

instruction. We, as well as the trial court, are bound to follow our supreme 

court’s precedent. See, e.g., State v. Hastings, 466 N.W.2d 697, 700 (Iowa Ct. 

App. 1990). The trial court did not commit error in using the inference 

instructions, and accordingly, we affirm. 

AFFIRMED.

 

2 Green did not object and does not now contend that Instruction No. 21 is anything 

other than a correct statement of Iowa law.
