STATE OF WISCONSIN IN COURT OF APPEALS DISTRICT III

STATE OF WISCONSIN,

PLAINTIFF-RESPONDENT,

V.

RYAN LEWIS STEINHOFF,

DEFENDANT-APPELLANT.

APPEAL from a judgment of the circuit court for Dunn County: JAMES M. PETERSON, Judge. Affirmed.

Before Stark, P.J., Hruz, and Gill, JJ.

Per curiam opinions may not be cited in any court of this state as precedent

or authority, except for the limited purposes specified in WIS. STAT. RULE 809.23(3).

¶1 PER CURIAM. Ryan Lewis Steinhoff appeals from a judgment of conviction, entered pursuant to a jury’s verdicts following a bifurcated trial, for No. 2024AP2506-CR

first-degree intentional homicide with the use of a dangerous weapon, as a party to the crime and as a repeater.1 On appeal, Steinhoff argues that the circuit court erred by excluding third-party perpetrator evidence, which deprived him of his constitutional right to present a defense. Relatedly, Steinhoff also asserts that the court erred by denying Steinhoff’s motion to admit other-acts evidence regarding the nature and circumstances of the third-party perpetrator’s past crimes. For the reasons that follow, we reject Steinhoff’s arguments, and we affirm his judgment of conviction.

BACKGROUND

¶2 On November 17, 2020, law enforcement discovered Brooks Monroe’s badly beaten body in a trailer home in Dunn County.2 The State alleged at trial that “after not sleeping for days, binging on as much methamphetamine as he could find, [Steinhoff] believed that [Monroe] was some sort of sex trafficker or some sort of predator.” As a result, Steinhoff, along with Ashley Gunder and Chad Turgeson, took Monroe to a trailer owned by George Welch, where the State alleged that Steinhoff and Turgeson assaulted Monroe to “teach[]” him “a lesson,” and Monroe died from his wounds.

1 Steinhoff was also convicted of misdemeanor retail theft, as a party to the crime and as a repeater, and two counts of felony bail jumping, as a repeater. Because these convictions are not relevant to Steinhoff’s appeal, we will not discuss them further. 2 Pursuant to the policy underlying WIS. STAT. RULE 809.86 (2023-24), we refer to the homicide victim in this case by a pseudonym. Although homicide victims are excluded from the confidentiality rule set forth in RULE 809.86(4) (2023-24), we nonetheless apply the rule here to protect the privacy of the victim’s family. See RULE 809.86(3), (5) (2023-24).

2 No. 2024AP2506-CR

¶3 Before trial, Steinhoff moved to admit third-party perpetrator evidence, pursuant to State v. Denny, 120 Wis. 2d 614, 357 N.W.2d 12 (Ct. App. 1984), alleging that Welch was the one who was actually responsible for Monroe’s death. Steinhoff’s theory was that Monroe survived the beating, but Welch struck Monroe in the head with a hammer after Steinhoff left the trailer. Steinhoff’s motion alleged that Welch had a motive to kill Monroe because “Welch is a person who irrationally engages in violent behavior,” as evidenced by his history of violent crimes, and because Welch sent a text message stating that he “felt better” as a result of Monroe’s death; that Welch had the opportunity to kill Monroe because Welch was home at the time and Steinhoff alleged that Monroe was alive when he left Welch’s residence; and that Welch had a direct connection to the crime because his DNA was the only other DNA located on a hammer that had Monroe’s blood on it.

¶4 Steinhoff also filed a motion to admit other-acts evidence “related to” his Denny motion. That motion sought to introduce evidence of Welch’s past violent crimes, arguing that the evidence was relevant to motive, identity, and modus operandi. See State v. Sullivan, 216 Wis. 2d 768, 771-72, 576 N.W.2d 30 (1998). The State opposed both motions.

¶5 The circuit court held a nonevidentiary hearing on the motions and, ultimately, denied the motions by oral ruling. The court did not specifically address all of the purposes for which the other-acts evidence was offered, but it nevertheless concluded that Welch had no motive to kill Monroe because Welch’s prior crimes “appear to be spontaneous eruptions of violence based on an interaction,” but there was “absolutely no evidence of any interaction between George Welch and [Monroe].” The court also determined that Steinhoff had failed to establish that Welch had a direct connection to the crime because “there’s just

no evidence that [Welch] was involved with what was going on, other than his DNA being on his own property in his own home.”

¶6 Steinhoff’s case proceeded to a nine-day bifurcated jury trial.3 Turgeson, Gunder, and Welch, among others, testified for the State. According to the trial testimony, Steinhoff, Turgeson, and Gunder were together consuming methamphetamine before Steinhoff and Gunder went to Monroe’s residence. Monroe’s roommate explained that they “chatted for a while” and “ended up hanging out for quite some time, playing cards.” The roommate testified that during the visit, Steinhoff “consistently brought up questions about what had happened to [Monroe’s son]” and was “asking questions about [child] trafficking,” while “fidget[ing] with a knife.” According to the roommate, Steinhoff consumed more methamphetamine, and Gunder testified that she also consumed more as well. Eventually, Steinhoff, Gunder, and Monroe left with Monroe’s dog.

¶7 The group then drove to Welch’s trailer, picking up Turgeson on the way. Welch was not home, but Gunder broke in through the window and let the others in. Turgeson described Welch’s trailer as “trashed” and “a trap house,” explaining that “[t]here was … four feet of refrigerator, open cans, needles, backpacks, furniture, you name it, mattresses all through the hallway.” According to the trial testimony,4 Steinhoff and Monroe went into the middle bedroom of the

3 Steinhoff pled not guilty and not guilty by reason of mental disease or defect (NGI) to the charges. An NGI trial is bifurcated into two phases: the guilt phase and the responsibility phase. See State v. Fugere, 2019 WI 33, ¶26, 386 Wis. 2d 76, 924 N.W.2d 469. 4 As the State explains, Gunder’s and Turgeson’s testimony differed as to the extent of Turgeson’s involvement in the crime after they entered Welch’s residence, but those differences are not relevant for the purpose of this appeal. We will address the testimony as it relates to Steinhoff.

trailer, and witnesses heard a “fist fight” and “somebody getting hit and yelling.” Gunder testified that Steinhoff “was just trying to figure out where the sex ring was,” and she remembered Monroe saying “he was sorry, that he did it” and also saying “he didn’t do it.”
