MICHAEL CHARLES DAUGHERTY,

 DEFENDANT-APPELLANT.

APPEAL from a judgment of the circuit court for Rock County: 

KARL HANSON, Judge. Affirmed. 

Before Blanchard, Graham, and Taylor, 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. Michael Daugherty appeals a judgment of 

conviction for operating a motor vehicle while intoxicated (OWI), as a sixth 
No. 2023AP1168-CR

2

offense, following a jury trial. Daugherty argues that the circuit court erroneously 

exercised its discretion when it denied his motion for a mistrial on the second day 

of a four-day trial. The asserted ground for a mistrial was that the jury had been

exposed to an audiovisual recording of police activity during which an 

unidentified voice, apparently a dispatcher, was heard to say the phrase “five 

priors” following Daugherty’s arrest and in an apparent reference to him. 

Daugherty contends that, because this phrase could have been heard and 

understood by jurors in a way that was prejudicial to him, “it cannot be said that 

[the] jury was sufficiently impartial.” Therefore, he contends, the court was 

obligated to declare a mistrial. We conclude that Daugherty has not clearly shown 

that the court erroneously exercised its discretion in denying the motion and 

accordingly affirm. 

BACKGROUND

¶2 Daugherty crashed a car at an intersection in Beloit at approximately 

7:00 p.m. one Sunday evening in August 2019. Responding police arrested 

Daugherty. As pertinent to this appeal, the State charged him with a violation of 

WIS. STAT. § 346.63(1)(a) (2021-22).1 

¶3 At trial, Daugherty’s former wife and her current husband testified

that Daugherty, before his arrest that evening, arrived unexpectedly at their 

residence. According to these witnesses, after brief interactions that included a 

verbal altercation with the current husband, Daugherty got into his car and drove 

away at a “high rate of speed.” He then proceeded to drive around the block

several times in a “[r]eckless” manner. He hit a curb and crashed the car. Police 

arrived on the scene a few minutes later. 

¶4 Daugherty gave trial testimony that is difficult to track at times, but 

it included the following. After he had negative interactions with people at his 

former wife’s house, and while he was “upset” and “angry,” he “took off” in his 

car. Shortly thereafter he apparently returned to his former wife’s residence, 

where someone hit him on the head while he had the driver’s side window 

lowered. He then drove again, at which time “somebody” “grabb[ed] at my 

steering wheel,” trying “to pull me out of the car.” Because of this, “I couldn’t 

make the corner.” The car “hit the curb, and I thought I had a flat.” 

¶5 Daugherty further testified that he did not consume any alcohol on 

the day of the crash until after the crash. More specifically, he testified that he got 

out of the car and ran to hide in a bush, where he drank a full pint bottle of 

whiskey that had been in the pocket of his shorts. Police found him in the bush

after about 20 to 30 minutes. He hid in the bush because he was afraid that people 

from his former wife’s residence might “jump[ him] again.” 

¶6 One witness called by the prosecution was a person who resided near

the crash scene. This witness testified that he saw the crash occur, after which 

Daugherty “jumped out of the driver’s side and took off running.” No one else 

was in the car with Daugherty at the time of the crash. This witness immediately 

tried to follow Daugherty, lost sight of him at first, but then saw him “in the 

bushes.” The police arrived within five minutes of the crash. 

¶7 Officer Zachary Stec, who was among officers who responded to the 

report of the car crash, testified in part as follows. Stec discovered Daugherty

where witnesses had reported that police would find him: “lying in a bush” near 
No. 2023AP1168-CR

4

the crash scene. Stec handcuffed Daugherty. After this, Daugherty: did not 

follow Stec’s instructions about how to stand up while handcuffed; “could not 

maintain his balance upon standing”; emitted “a strong odor of intoxicants” on his 

breath and from his person; and spoke in a “very slurred” manner. In addition, 

Daugherty’s eyes were “extremely bloodshot and glassy.” 

¶8 Stec further testified that Daugherty was placed in the back seat of a 

squad car, at which time he became “loud and boisterous and began blowing on 

my rear camera, putting his mouth up to the camera and blowing extremely fast, 

which [Stec] felt was odd behavior.” Daugherty denied to police that he had 

driven the crashed car, but police found a key to the car in his pocket. Stec did not 

“see anything discarded” when Daugherty emerged from the bush, and Stec did 

not find any alcohol containers.

¶9 A police-worn body camera recording viewed by the jury reflects 

that, after the arrest, Officer Stec asked Daugherty if he had “anything to drink 

today,” and that Daugherty responded, “Oh, yeah, a little bit.” 

¶10 Pursuant to a warrant for a blood draw, Daugherty was found to have 

a blood alcohol concentration of .178. 

¶11 Defense witnesses included a person who testified that, as of the 

time of trial, she had been in a romantic relationship with Daugherty since 2018, 

and that the two resided together on the day of his arrest. This witness testified 

that Daugherty left the residence a little after 6:00 p.m. that day, at which time he 

“[s]eemed fine and normal” and did not appear to be impaired. She also testified 

that she had not observed him drink alcohol that day. She testified that it was a 

30- to 35-minute drive from their residence to Daugherty’s former wife’s 

residence.

¶12 The defense also called a hospital pharmacist and consultant who 

holds a doctorate in clinical pharmacology. This witness testified that the 

following was “very plausible”: assuming that Daugherty had a blood alcohol 

level of zero at the time of the crash at approximately 7:00 p.m., and further 

assuming that he swiftly consumed one pint of whiskey (40 percent alcohol by 

volume) over the course of approximately 10 to 12 minutes beginning 

immediately following the crash, his blood alcohol concentration could have 

reached .178 by the time his blood sample was drawn at approximately 10:00 p.m. 

that night.

¶13 At the end of a four-day trial, the jury returned a guilty verdict for a 

violation of WIS. STAT. § 346.63(1)(a), the charge on which Daugherty was 

convicted and sentenced. 

¶14 We now turn to the aspect of the trial at the heart of this appeal. On 

the second day of trial, the prosecution offered as evidence, and proposed to 

publish to the jury, recordings containing video and sound captured by (1) the 

body camera that Stec was wearing that evening, and (2) a forward-facing camera

mounted on the dashboard of Stec’s squad car. With no objections by the defense,

the circuit court admitted this exhibit containing the two recordings and allowed

them to be played for the jury.2

 

2

 The admitted and published-to-the-jury Exhibit 14, which contains the body camera 

and dashboard camera recordings, is not in the appellate record. As discussed below, this means 

that we assume that all pertinent aspects of the recordings support the challenged circuit court 

ruling. See Duhame v. Duhame, 154 Wis. 2d 258, 269, 453 N.W.2d 149 (Ct. App. 1989) 

(appellate courts assume that “every fact essential to sustain the trial judge’s exercise of 

discretion is supported by” pertinent material that has been omitted from the record).

¶15 The prosecutor played portions of the audiovisual body camera 

recording first, pausing at intervals to pose questions to Stec. Then, with Officer 

Stec still on the witness stand, the prosecutor played a portion of the dash camera

audiovisual recording. Shortly after this recording began playing, defense counsel 

asked for a sidebar and, outside the presence of the jury, requested a mistrial based 

on one phrase spoken by a dispatcher during the course of police “radio chatter” 

audible on the recording that the jury had just heard. After the parties and the 

court, still outside the presence of the jury, listened to the recording a second time, 

the circuit court made the following factual findings about the content of the 

recording and what the court perceived to be its likely effects on the jury. 

¶16 Officer Stec and another officer are shown interacting with 

Daugherty. The jury had already observed, in viewing the body camera recording, 

aspects of this same sequence of events. But this time the vantage point is the 

dash camera and police dispatch audio could be heard. Daugherty is handcuffed, 

the officers are seeking information about him from dispatch, and they are about to 

move him into the squad car. More specifically, one officer gets on the police 

radio and calls in to dispatch with Daugherty’s name. There is a pause. A 

dispatcher responds with words that include “valid,” followed by something 

unintelligible, and then the dispatcher can be heard to say, “five priors.” The 

video continued to play for about 35 more seconds, showing other interactions 

involving police, before defense counsel requested a sidebar and the jury was 

dismissed. 

¶17 The circuit court found that the phrase “five priors” was “very 

audible” to the court, and the prosecutor acknowledged that he could hear that 

phrase after replaying the recording. But at the same time, the court suggested that 

jurors might have missed it under all of the circumstances. The court credited

7

statements by the prosecutor that he had played the dash camera recording before 

trial and had not heard “five priors” and that the prosecutor had also not heard that

phrase when it was played for the jury. 

¶18 The circuit court noted that the court had been watching the jury as 

the dash camera recording was played. “The jury was attentively watching the 

video and [jurors] were watching this interaction” between the two officers and 

Daugherty. The phrase “five priors” was not stated as “a direct answer from an 

officer testifying about something,” nor did it come out of the mouth of one of the 

officers whom the jury was attentively watching in the recording. Instead, it came 

from “a disembodied voice.” Further, the court described the phrase “five priors” 

as being “baseless.” We interpret this to represent a finding that the phrase lacked 

meaningful context—that it was not explained or elaborated on through any 

additional information to which the jury was exposed. 

¶19 The circuit court found that, in the context of the case as tried to that 

point, there “is some ambiguity as to what” the phrase “five priors” would have 

meant to any juror who did hear it and thought about it. The court said that judges 

and attorneys, knowing that Daugherty was being tried on a charge of OWI, as a 

sixth offense, “immediately jump to the idea that five priors” means “five OWI 

priors.” But “that is a logical leap based upon” the general awareness of judges 

and attorneys and knowledge about this case that the jury here was not privy to. 

For the jury here, “that is not necessarily the most logical leap to make.” It could

have meant to them “five prior police contacts,” or else “five prior criminal 

convictions” not involving OWI. Further, the court noted that it had already 
No. 2023AP1168-CR

8

determined that if Daugherty were to testify—as in fact came to pass—the jury 

would learn that Daugherty had three prior convictions, not five.

3

 

¶20 Concluding that there was “minimal prejudice” to Daugherty from 

the “five priors” reference, the circuit court denied the motion for a mistrial.

Daugherty appeals, challenging only the denial of his motion for mistrial.

DISCUSSION

¶21 The circuit court observed, and the State now agrees, that there was 

the potential for prejudice to Daugherty. That is, the fact that the jury was 

exposed to the dispatcher saying, “five priors,” in an apparent reference to 

Daugherty raised at least some risk that jurors might conclude that this meant that 

Daugherty had been convicted of five offenses, which might have included one or 

more OWI offenses. This in turn created a risk that the jury would improperly rely 

on the potential existence of prior OWI offenses in reaching its guilty verdict on 

the OWI count at issue in this appeal. But under the legal standards that we now 

summarize, the issue is not whether there was a potential risk of prejudice. 

Instead, the issue is whether Daugherty has clearly shown, based on all of the facts 

and circumstances, that declaring a mistrial was a manifest necessity. We 

conclude that Daugherty has not made that clear showing.

¶22 Our supreme court recently summarized applicable standards:

When faced with a motion for mistrial, “the circuit 

court must decide, in light of the entire facts and

 The circuit court ruled, outside the presence of the jury that, under WIS. STAT.

§ 906.09, Daugherty could be impeached with the fact that he had three prior convictions. 

Consistent with this ruling, when Daugherty took the witness stand at trial he testified that he had 

been convicted of a crime three times.

circumstances, whether ... the claimed error is sufficiently 

prejudicial to warrant a mistrial.” State v. Ford, 2007 WI 

138, ¶29, 306 Wis. 2d 1, 742 N.W.2d 61. We review a 

circuit court’s decision to grant or deny a motion for 

mistrial for an erroneous exercise of discretion. Id. “An 

erroneous exercise of discretion may arise from an error in 

law or from the failure of the circuit court to base its 

decisions on the facts in the record.” Id., ¶28 (quoting 

State v. Raye, 2005 WI 68, ¶16, 281 Wis. 2d 339, 697 

N.W.2d 407). “Discretion is not synonymous with 

decision-making. Rather, the term contemplates a process 

of reasoning.” State v. Gallion, 2004 WI 42, ¶3, 270 

Wis. 2d 535, 678 N.W.2d 197 (quoting McCleary v. State, 

49 Wis. 2d 263, 277, 182 N.W.2d 512 (1971)).

State v. Debrow, 2023 WI 54, ¶15, 408 Wis. 2d 178, 992 N.W.2d 114. “‘The 

denial of a motion for mistrial will be reversed only on a clear showing of an 

erroneous use of discretion’ by the circuit court.” State v. Doss, 2008 WI 93, ¶69, 

312 Wis. 2d 570, 754 N.W.2d 150.

¶23 Elaborating on the statement in Ford, quoted in Debrow, that the 

circuit court is to consider “‘the entire facts and circumstances,’” this includes

consideration of the relative strength of the prosecution’s case. Oseman v. State, 

32 Wis. 2d 523, 528-29, 145 N.W.2d 766 (1966) (strength or weakness of case 

relevant to determine if “error” forming basis for mistrial motion “is prejudicial”).

¶24 We begin the analysis by noting that Daugherty does not argue that 

the circuit court committed clear error in making any finding of fact regarding the 

 

4

 The State includes a section in its brief with the heading, “Any error in denying 

Daugherty’s mistrial motion was harmless,” and it cites as authority an opinion involving 

harmless error analysis in the context of a constitutional challenge to a jury instruction in a 

criminal case. We question whether the harmless error doctrine could apply in the context here. 

However, we construe the substantive points made by the State in this section of its brief as being 

equivalent to an argument that the circuit court did not erroneously exercise its discretion in 

denying the mistrial motion in part because the entire facts and circumstances here included a 

strongly supported prosecution case and a weakly supported theory of defense.

playing of the dash camera recording or the nature of its contents. Further, by 

failing to include the recording in the record, Daugherty has left us to assume that,

if we were to observe and listen to the recording, our viewing would support the 

circuit court’s suggestion that, while the phrase “five priors” was “very audible” to 

the court, jurors who were focusing on the conduct of the officers visible in the 

recording might not have heard or focused on the one-time reference by a 

“disembodied voice” to “five priors.” See Duhame v. Duhame, 154 Wis. 2d 258, 

269, 453 N.W.2d 149 (Ct. App. 1989).

¶25 The circuit court pointed out that 35 seconds passed from the time 

the phrase “five priors” could be heard, for the first and only time by jurors, until 

the dash camera recording was stopped and the jury was excused. This contrasts 

with the way the prosecution presented the body camera video, before the dash 

camera video was played—namely, stops and starts of the body camera recording, 

interspersed with questions posed to Officer Stec that focused on aspects of the 

recording. This supports the court’s conclusion that the jury was not likely to 

hear, consider, and misuse in its deliberations the phrase “five priors.” 

¶26 It is true, as noted above, that the circuit court and the State now on 

appeal assume a risk of prejudice. These assumptions are consistent with the 

caution from our supreme court about the dangers of propensity inferences that 

jurors may make in connection with prior convictions in OWI cases. See State v. 

Warbelton, 2009 WI 6, ¶¶46-47, 315 Wis. 2d 253, 759 N.W.2d 557. The court 

has noted that, “upon learning that the defendant has prior convictions, 

suspensions, or revocations, jurors are likely to infer that these prior offenses were 

also for drunk driving,” and that “upon learning that the defendant had multiple 

prior offenses, jurors are likely to infer that the current charge is part of a pattern 

of behavior.” Id., ¶47. From these assumptions “jurors might conclude that even 
No. 2023AP1168-CR

11

if the defendant is not guilty on the particular occasion charged, the defendant 

likely committed the same offense on many other occasions without being 

caught.” Id.

¶27 At the same time, however, the jury here was not exposed to 

unambiguous testimony that Daugherty had five prior OWI convictions or even 

five prior convictions, but instead only a voice saying “five priors.” Indeed, the 

jury was informed through Daugherty’s own unchallenged testimony that he had 

been convicted of a crime three times.

5

 For this reason, any juror who heard and 

focused on the “five priors” reference, and from this speculated that this meant 

five prior convictions for a crime, would have had contrary evidence to consider. 

Put somewhat differently, the “five priors” reference added no new basis for any 

juror who would unfairly and unreasonably assume that Daugherty was guilty of 

the charged OWI because he has prior convictions, which could include one or 

more OWI offenses—such a juror already had a basis for such an unfair and 

unreasonable conclusion through Daugherty’s testimony.

¶28 Further, the circuit court was exceptionally careful in making a 

detailed record and also in giving Daugherty a full opportunity to present 

arguments and offer any curative instructions that he might suggest. The court 

agreed with Daugherty’s position that any instruction would only serve to draw the 

jury’s attention to the reference, to Daugherty’s potential disadvantage. Daugherty 

does not criticize any aspect of the court’s handling of this incident except to 

challenge its ultimate decision to not grant a mistrial.

 

5

 Daugherty does not challenge the circuit court’s decision that he could be impeached 

with the fact that he had been convicted of three criminal offenses.
No. 2023AP1168-CR

12

¶29 Another factor weighing against reversal of the circuit court’s 

discretionary decision was the strength of the prosecution’s evidence and the 

weakness of the defense theory. See Oseman, 32 Wis. 2d at 528-29. As 

summarized above, there was strong, consistent evidence that, at the time of the 

crash, Daugherty had “consumed a sufficient amount of [alcohol] to cause [him] to 

be less able to exercise the clear judgment and steady hand necessary to handle 

and control a motor vehicle.” See WIS JI—CRIMINAL 2664. In contrast, the 

record suggests that his defense that he swiftly downed a pint of whiskey in the 

bushes was not strong. For example, the testimony of his romantic partner was not 

especially exculpatory on its face, in that it left time for him to have consumed a 

large quantity of alcohol between the moment when she testified he left their 

residence while appearing sober and the moment of the crash. Further, a major 

premise of the defense expert’s testimony was to assume the truth of Daugherty’s 

account of drinking voluminously in the bush immediately after the crash. 

¶30 Daugherty attempts unsuccessfully to analogize this case to 

Mulkovich v. State, 73 Wis. 2d 464, 243 N.W.2d 198 (1976). In that case, our 

supreme court concluded that the circuit court committed prejudicial error by 

reading to a newly empaneled jury the portion of the information alleging that the 

defendant was a repeat offender who had previously been convicted of a felony. 
No. 2023AP1168-CR

13

Id. at 467. The facts in Mulkovich are so different that it does not support the 

proposition that a mistrial was required on the facts here.6

CONCLUSION

¶31 For all of these reasons, we affirm the judgment.

By the Court.—Judgment affirmed.

This opinion will not be published. See WIS.

STAT. RULE 809.23(1)(b)5.

 We call to the attention of Daugherty’s counsel that both of his appellate briefs fail to 

comply with WIS. STAT. RULE 809.19(8)(bm), which addresses the pagination of appellate briefs. 

See RULE 809.19(8)(bm) (when paginating briefs, parties must use “Arabic numerals with 

sequential numbering starting at ‘1’ on the cover”). This rule has been amended, see S. CT.

ORDER 20-07 (eff. July 1, 2021), in light of the general requirement of electronic filing of briefs 

in PDF format and the fact that briefs are electronically stamped with page numbers when they 

are accepted for e-filing. As our supreme court has explained, the new pagination requirements 

ensure that the numbers on each page of a brief “will match ... the page header applied by the 

eFiling system, avoiding the confusion of having two different page numbers” on each page.
