JAROSH, Justice.
[¶1] A jury convicted Marvin Emmett Brown of three drug-related felonies and three
misdemeanors. Mr. Brown appealed, alleging the district court erred in not allowing him
to file a second motion to suppress and by improperly admitting evidence that should have
been excluded pursuant to Wyoming Rule of Evidence (W.R.E.) 404(b). Finding no error,
we affirm.
ISSUE
[¶2] We find the following issues dispositive of Mr. Brown’s appeal:
1. Did Mr. Brown waive his right to challenge a free-air sniff of his truck
by failing to raise the challenge in a timely manner and, if so, was there
good cause for the failure?
2. Did the district court err by admitting uncharged misconduct evidence at
trial?
FACTS
[¶3] On September 12, 2024, Wyoming Department of Criminal Investigation (DCI)
special agents Darren Willis and Eric Ford planned to surveil suspects they believed were
involved in the distribution of controlled substances in Rawlins, Wyoming. The DCI
agents met with Carbon County Sheriff Deputies Christopher Fischer and David Greninger
and requested their local assistance for traffic “wall” stops and for Deputy Greninger’s K9
partner, Nako’s, assistance.1 At that time, Deputy Greninger and Nako had each completed
120 hours of training, plus an additional sixteen hours of monthly training to maintain their
certifications. Nako originally began his certification process with another handler in Utah,
but because they failed to bond, he was sent to Deputy Greninger.
[¶4] Agent Ford began his surveillance and drove past Mr. Brown’s residence. Although
Mr. Brown was not a suspect agents intended to surveil, Agent Ford noticed a familiar
vehicle in front of his residence that belonged to two known drug users/distributors (NB
and AF) in Rawlins. Agent Ford then notified Agent Willis and the deputies of this
observation.
[¶5] Deputy Fischer received the information, and after AF left Mr. Brown’s residence
in her vehicle, Deputy Fischer pulled AF over for failure to stop at a stop sign. Deputy
1
Agents Willis and Ford testified that wall stops are traffic stops conducted by local law enforcement to
gather information while at the same time ensuring suspects are not tipped off to DCI investigations.
1
Greninger and Nako arrived on scene, and Nako positively alerted on the vehicle.
However, after a search of the vehicle, no controlled substances were found.
[¶6] Meanwhile, Agent Willis drove to Mr. Brown’s residence, where he observed Mr.
Brown leaving in a pick-up truck. Agent Willis followed Mr. Brown to a gas station but
did not observe any traffic violations. On Mr. Brown’s way home, both Agent Willis (in
an unmarked car) and Deputy Fischer (in a patrol vehicle) briefly followed Mr. Brown.
While Deputy Fischer abandoned that surveillance, Agent Willis continued following Mr.
Brown and eventually observed him drive through a four-way stop intersection without
stopping. Agent Willis then notified Deputy Fischer of that violation.
[¶7] Based on this information, Deputy Fischer initiated a traffic stop of Mr. Brown’s
truck and Deputy Greninger and Nako provided backup.2 Mr. Brown was driving the truck,
and Misty Lascano was his passenger. As Deputy Fischer processed information related
to the traffic stop, Deputy Greninger asked Mr. Brown to exit the truck, and Nako began
performing a free-air sniff of the vehicle. Mr. Brown declined consent to a search of the
vehicle, but stated everything inside belonged to him. While Nako performed the free-air
sniff, Mr. Brown sat in the back of Deputy Fischer’s patrol vehicle.
[¶8] Nako alerted to the presence of controlled substances next to the driver’s side door.
Shortly thereafter, Mr. Brown began punching the window from inside Deputy Fischer’s
vehicle and screamed at Ms. Lascano to take the truck and leave so officers could not search
it. Deputies then restrained Mr. Brown, asked Ms. Lascano to step out of the vehicle, and
searched the vehicle. The search revealed approximately 309 grams of methamphetamine,
including packaging materials. Deputies also found two small bags containing suspected
marijuana, and a small black pouch with eleven smaller bags, some containing one ounce
and others containing an eighth of an ounce of methamphetamine officers believed were
meant for distribution.
[¶9] A Rawlins police officer frisked Mr. Brown and then placed him in a Rawlins Police
Department vehicle for transport. After Mr. Brown was moved from Deputy Fischer’s
patrol vehicle, officers found a small bag of methamphetamine and a handgun stashed on
the floor of the vehicle’s backseat where Mr. Brown had been sitting.
[¶10] Law enforcement later obtained a warrant to search Mr. Brown’s home, which they
executed the next day. There, they found a large amount of packaging material, including
small plastic bags, a scale, a tray with suspected methamphetamine residue, drugs and drug
paraphernalia, a number of firearms, firearm parts, and ammunition.
2
Agent Willis did not perform the traffic stop because his vehicle was unmarked and not set up for traffic
stops, and he personally is not equipped or intended to make traffic stops.
2
[¶11] The State charged Mr. Brown with eight criminal violations: 1) possession of
methamphetamine with intent to deliver (second or subsequent offense); 2) possession of
a felony amount of methamphetamine; 3) conspiracy to deliver methamphetamine; 4)
possession of a firearm while committing a felony; 5) possession of a felony amount of
marijuana (4th or subsequent offense); 6) interference with a police officer; 7) possession
of a firearm while being a non-violent felon; and 8) failure to stop at a stop sign.3
[¶12] In preparation for trial, Mr. Brown filed a demand for notice of and objection to any
Rule 404(b) evidence the State intended to introduce. The State, in turn, identified five
items of 404(b) evidence it intended to use at trial:
1. Testimony from a confidential informant about a conversation with a
third party who told the informant he would be buying methamphetamine
from Mr. Brown to resell.
2. Testimony from Agent Willis about his observation of three different
controlled substance users and distributers at Mr. Brown’s home.
3. Testimony from Agent Willis about observing NB and AF at Mr.
Brown’s residence on the day of Mr. Brown’s arrest including the search
of AF’s vehicle, AF’s probation status for possessing methamphetamine,
and finding synthetic urine during the search.
4. Text and Facebook messages from Ms. Lascano that referenced drug
activity.
5. Text and Facebook messages from Mr. Brown to five other individuals,
some of which contained coded references related to the sale of controlled
substances.
[¶13] The messages sent between Mr. Brown and five individuals included
communications about “groceries” and “parts.” For example, the following
communications occurred between Mr. Brown and “KK” through Facebook messenger.
KK – Hey. Was needing some groceries
Mr. Brown: K
…
KK – Hungry looking for groceries
Mr. Brown – I’m home
3
The State charged Ms. Lascano separately with possession of methamphetamine with intent to deliver,
felony possession of methamphetamine, and conspiracy to deliver methamphetamine. Her case was joined
with Mr. Brown’s for trial.
3
KK: OK. I’ll be by in about 30
…
Mr. Brown: I’m going shopping today
KK: Nice. I’ll see what I have here soon when my pay hits
…
Mr. Brown: Ya I might be going groceries [sic] shopping
KK: Nice let me know
…
Mr. Brown: How much more do you need
KK: 1/2 a beef
Mr. Brown: OK.
…
Mr. Brown: I’m going shopping soon
KK: Sweet. Let me know
Mr. Brown: K
KK: Are you out of groceries?
Mr. Brown: Ya I’m out
KK: Damn
KK: Still nada?
Mr. Brown: I’m going Saturday to pick up a whole beef if you still
want me to get a little for you
KK: Certainly.
The following messages occurred between Mr. Brown and “FMV,” also through Facebook
messenger:
Mr. Brown: I’m headed to get the part for you
FMV: OK thanks lmk when to get it from you?
…
FMV: Hey what are you doing I was wondering if you possibly
had anymore green chili you could get rid of? Let me know I’ll
be at work for a while okay thanks
Mr. Brown: How much gr chili
FMV: 50
FMV: or what ever you can?
Mr. Brown: OK.
…
FMV: Hey, I am going to try to quit I’m going to be done with
day three so tell me no if I ask please.
Mr. Brown: OK.
Mr. Brown and “ML” also exchanged messages, referring to “parts” and “batter[ies]” and
needing “2 pack[s] of 8.” Mr. Brown and “M” also messaged and referenced “wondering
4
if you have any right now,” and “[h]e would like the usual please.” “M” also said, “Got
your $,” and Mr. Brown responded, “I just woke up and I have to go back and get my
g[r]oceries.” Finally, a fifth individual, “A” and Mr. Brown exchanged messages about
money and meeting up.
[¶14] The district court held a hearing on the Rule 404(b) matters. In a subsequent written
order, the court ruled all three categories of testimony the State sought to admit were not
relevant and therefore inadmissible under Rule 404(b). However, the court found the text
and Facebook messages sent by both Ms. Lascano and Mr. Brown were relevant to the
charges, and that “balancing the weight of the probative nature and the potential for unfair
prejudice,” the State could attempt to admit the evidence at trial.4
[¶15] Mr. Brown also filed a motion to suppress.5 He argued the initial stop was not
justified at its inception, contesting Agent Willis’s observation of his failure to stop at a
stop sign and arguing the stop was a “fishing expedition.” The State disagreed and in
response argued the stop was supported by reasonable suspicion. The State also asserted
Nako’s alert provided sufficient probable cause for the resulting search.
[¶16] On the same day in early January when the hearing on the motion to suppress was
scheduled to take place, Mr. Brown’s attorney filed a motion to withdraw. The court
granted the motion to withdraw and did not consider the motion to suppress at that time.
[¶17] The district court held a pretrial conference four days later, on January 13, 2025,
during which Mr. Brown represented himself and indicated he was working on hiring a
new attorney. The district court acknowledged Mr. Brown filed a motion for continuance
of the February 2025 trial date and a waiver of speedy trial, and granted the continuance
for one month, setting the case for trial in March 2025.
[¶18] On January 22, 2025, a new attorney entered her appearance for Mr. Brown. She
filed another motion to continue the trial, stating she needed more time for discovery and
indicated she might supplement the original motion to suppress filed by Mr. Brown’s
previous attorney. The district court granted the motion to continue, resetting the trial for
April 2025 and setting the suppression hearing on Mr. Brown’s first motion to suppress for
March 3, 2025.
[¶19] The district court held the suppression hearing as scheduled. During the hearing,
the State called Deputies Fischer and Greninger and Agent Willis to testify. Each testified
4
Ultimately, the text messages between Ms. Lascano and other individuals were deemed inadmissible at
trial. The district court found the messages inadmissible under the co-conspirator exception and found the
State had not made a prima facie showing a conspiracy existed between Mr. Brown and Ms. Lascano. The
same statements were also deemed inadmissible under W.R.E. 804(b)(7).
5
The court extended the original motion filing deadline from December 2, 2024, to December 16, 2024,
and Mr. Brown’s motion was timely filed on December 16, 2024.
5
about his involvement in the traffic stop that led to Mr. Brown’s arrest. Deputy Fischer
admitted he had not seen Mr. Brown’s traffic violation, but initiated the stop based on
Agent Willis’s observation of Mr. Brown’s failure to stop at a stop sign.
[¶20] Deputy Greninger testified about Nako’s free-air sniff, and detailed his and Nako’s
training. During cross-examination, Deputy Greninger explained Nako previously worked
with another law enforcement officer, and testified Nako alerted on Mr. Brown’s truck
during his second pass of the vehicle. Mr. Brown’s counsel then asked, “In your training,
what are you trained to do to not alert or not pass your ideas to the dog? In other words,
not make them alert?” The State objected, arguing the question was outside the scope of
the suppression issue. Mr. Brown’s counsel explained she just joined the case and argued
the parties would have to address the issue in the future. The district court sustained the
objection.
[¶21] Agent Willis testified last. He explained the “wall-stop” process and shared his
observations of Mr. Brown’s failure to stop at the four-way stop.
[¶22] The day after the suppression hearing, on March 4, 2025, Mr. Brown filed a third
motion to continue the trial. He argued his new counsel had first learned about the
existence of body camera footage at the suppression hearing and received the footage while
drafting the third motion to continue. While this motion to continue was pending, the
district court denied Mr. Brown’s motion to suppress, ruling there was reasonable suspicion
to justify Mr. Brown’s traffic stop.
[¶23] On March 10, 2025, the district court held a pretrial conference where it also
considered Mr. Brown’s third motion to continue. Mr. Brown asked for leave to file a late
motion to suppress and to move the trial date to accommodate additional motions. In
support of his desire to file a late motion to suppress, he cited the alleged missing body-
camera footage and Nako’s transfer from another law enforcement agency. Mr. Brown’s
attorney claimed she learned about both of those facts for the first time at the March 3
suppression hearing. Accordingly, Mr. Brown’s attorney had reached out to a potential
expert witness – the President of Detective Dog International, Kyle Heyen, to review the
case.
[¶24] The State responded that it already provided all of the discovery, including “body
cams,” on January 28, 2025, six days after Mr. Brown’s new counsel entered her
appearance. The State also argued the K9 certification information was also provided on
January 28. Additionally, the same discovery had also been provided to Mr. Brown’s
original counsel three months before, on November 15, 2024. Mr. Brown’s counsel then
argued the discovery she was provided did not include the body-camera footage, and the
previous attorney did not provide anything.
6
[¶25] The district court denied the motion to continue the trial. The court stated that
although it was “sympathetic” to Mr. Brown’s new counsel, Mr. Brown’s former counsel
already received the discovery and filed a motion to suppress. Then, the court addressed
the possible late filing of a motion to suppress and found the State sent the discovery
information to defense counsel “at least twice.” It clarified, “Information about the K9 was
in the original charging documents.” The court continued, “If you are compelled to file a
[late] motion, the [c]ourt will take a look at it, but … I won’t have any guarantees that the
[c]ourt will hear any motions.” Mr. Brown did not file any late or supplemental motions
to suppress.
[¶26] Prior to trial, the State filed a motion in limine to preclude Mr. Heyen’s testimony
and argued the issue of whether Nako’s alert was reliable went to the lawfulness of the
stop, which was properly a question for the court in a pretrial motion to suppress, not for a
jury during trial. Thus, Mr. Heyen’s testimony was irrelevant to the elements of the crimes
charged and was inadmissible under Rule 403 because it risked confusing the jury.
[¶27] The district court held a hearing on the State’s motion in limine in April 2025. Mr.
Brown argued testimony about the dog sniff was relevant to his theory of defense that
officers wanted to “get Mr. Brown at any cost.” Mr. Brown proffered that Mr. Heyen
would testify about whether Nako actually alerted or whether Deputy Greninger prompted
him to alert. The district court granted the State’s motion in limine, finding evidence about
Nako’s alert relevant to the legal question in a motion to suppress, not an issue of fact for
trial. It also concluded the evidence would likely confuse the jury.
[¶28] The case proceeded to trial in June 2025. Rule 404(b) was a central issue at trial.
In his opening statement, Mr. Brown mentioned the Rule 404(b) evidence related to AF,
which the court had already ruled was inadmissible, and introduced a theory of defense
that law enforcement colluded to stop Mr. Brown while driving and the drugs they found
were not his. After opening statements, the State requested the district court re-evaluate
its Rule 404(b) ruling related to the stop of AF based on Mr. Brown opening the door
during his opening statement. After no objection by Mr. Brown, the State elicited
testimony about the stop of AF through multiple witnesses.
[¶29] The State also introduced the Rule 404(b) evidence of text messages between Mr.
Brown and five individuals. The messages spanned from late September 2023 to
September 2024, and included the individuals and Mr. Brown discussing “groceries” and
other coded messaging. Mr. Brown objected to the messages as hearsay and lacking
relevance, which the court overruled.
[¶30] The jury convicted Mr. Brown of possession of methamphetamine with the intent
to deliver, separate counts of felony possession of methamphetamine and marijuana,
interference with a peace officer, possession of a firearm by a non-violent felon, and failure
to stop at a stop sign. He was found not guilty of using a firearm in the commission of a
7
felony. The district court sentenced Mr. Brown to time served for the interference and
possession of a firearm charges, and imposed a fine for failing to stop at a stop sign. It
merged his sentences for his methamphetamine convictions and sentenced him to thirty to
forty years in prison, and imposed a concurrent sentence of eighteen to thirty-six months
for the marijuana possession conviction.
[¶31] This appeal followed.
DISCUSSION
Mr. Brown waived his right to challenge a free-air sniff of his truck.
[¶32] Mr. Brown argues the district court violated his right to present a complete defense
by refusing to allow him to file a late motion to suppress to challenge the validity of Nako’s
free-air sniff alert. The State argues Mr. Brown waived this claim and failed to show good
cause. We agree with the State on both accounts.
[¶33] “While the question of waiver is often one of fact, when the facts and circumstances
relating to the subject are admitted or clearly established, waiver becomes a question of
law which we consider de novo.” Keller v. State, 2024 WY 72, ¶ 37, 551 P.3d 465, 477
(Wyo. 2024) (quoting Rodriguez v. State, 2019 WY 25, ¶ 16, 435 P.3d 399, 403 (Wyo.
2019)). “Because the record is clear and the facts relating to waiver are not disputed, our
review is de novo.” Id. (quoting Rodriguez, ¶ 16, 435 P.3d at 403)). Since Mr. Brown did
not attempt to make a good cause showing before the district court, it is appropriate for this
Court to ask whether the district court would have abused its discretion had it not found
good cause. Rodriguez, ¶ 39, 435 P.3d at 411 (citing United States v. Daniels, 803 F.3d
335, 352 (7th Cir. 2015)).
[¶34] W.R.Cr.P. 12(b)(3) requires a defendant to file a motion to suppress before trial.
Keller, ¶ 37, 551 P.3d at 477 (quoting Herrera v. State, 2019 WY 93, ¶ 18, 448 P.3d 844,
849 (Wyo. 2019)). Failure to do so generally waives the issue and precludes appellate
review. Id. The only exception is when the defendant demonstrates good cause for failing
to file the pretrial motion. Keller, ¶ 37, 551 P.3d at 477 (quoting Mathewson v. State, 2019
WY 36, ¶ 41, 438 P.3d 189, 205 (Wyo. 2019)). However, good cause cannot be established
if “the record reveals no impediment to the defendant’s ability to have raised the issue prior
to appeal.” Keller, ¶ 37, 551 P.3d at 477 (quoting Herrera, ¶ 18, 448 P.3d at 849).
[¶35] The same principle applies when a defendant does file a pretrial motion to suppress
but raises a new suppression argument for the first time on appeal. Under W.R.Cr.P. 12(g),
appellate review of that new argument is barred absent a showing of good cause. See
Keller, ¶ 37, 551 P.3d at 477 (quoting Mathewson, ¶ 41, 438 P.3d at 205). In other words,
a defendant may not obtain appellate review of a suppression argument he could have
raised before trial but did not. Id.
8
[¶36] At oral argument, Mr. Brown withdrew his appellate argument that any failure to
preserve the issue of the validity of Nako’s free-air sniff alert constituted forfeiture rather
than waiver. Accordingly, the question becomes whether Mr. Brown filed a timely
challenge to the K9 free-air sniff. The record plainly shows that he did not. Mr. Brown
did not raise the issue in his initial motion to suppress, nor did he file any subsequent or
supplemental motion raising it. While Mr. Brown indicated a desire to challenge the free-
air sniff alert, he never actually did so. In short, it is clear from the record that Mr. Brown
waived any issues with the validity of Nako’s free-air sniff alert. We therefore turn to
whether Mr. Brown has demonstrated good cause for that failure.
[¶37] Rule 12(g) allows a district court to “grant relief from waiver” if the court is satisfied
the defendant has shown good cause, and unless Mr. Brown is able to show an
“impediment” to his ability to raise the issue prior to appeal, good cause will not be
established. See, e.g., Herrera, ¶ 19, 448 P.3d at 849-50 (holding good cause existed for
failure to file a motion to suppress).
[¶38] Mr. Brown claims good cause existed for his failure to file a second motion to
suppress because his second attorney was unaware of the body-cam footage and Nako’s
history until the motion to suppress hearing. He also contends he sought leave to file a
second motion to suppress, which the district court denied. The record, however, does not
support Mr. Brown’s assertions and otherwise provides no basis for finding good cause for
his failure to file a second motion to suppress.
[¶39] The district court addressed Mr. Brown’s request to file a second motion to suppress
during the hearing on his third motion to continue the trial. Although the court denied the
motion to continue, it did not foreclose Mr. Brown from filing a second motion to suppress.
To the contrary, the court stated, “If you are compelled to file a motion the Court will take
a look at it.”
[¶40] The district court also found the State provided discovery to defense counsel “at
least twice.” Id. The record indicates Mr. Brown’s first attorney received the complete
discovery, including access to the body-camera footage before the motion filing deadline.
In addition, information about the K9 was contained in the original charging documents.
The fact that there was a K9 free-air sniff was also known to Mr. Brown from the outset,
as he personally observed Nako’s free-air sniff. Mr. Brown’s first attorney, who also
received additional time to review the discovery, then filed the first motion to suppress.
That motion, however, did not challenge Nako’s free-air sniff.
[¶41] Likewise, Mr. Brown’s second attorney also received the discovery. See United
States v. Walden, 625 F.3d 961, 966 (6th Cir. 2010) (holding the substitution of counsel
three weeks before a motion filing deadline did not amount to good cause). Importantly,
the district court did not foreclose Mr. Brown’s opportunity to file a second motion to
9
suppress. Instead, it expressly indicated it would consider such a motion if one were filed,
although it might not hold another hearing. Despite the district court’s stated willingness
to consider an additional motion, Mr. Brown never filed a second or supplemental motion.
This is true even though the court granted Mr. Brown’s motion to continue, which he filed
because he needed “time to receive and review discovery” and suggested he “may find it
necessary to supplement the Motion to Suppress.”
[¶42] Accordingly, the record demonstrates Mr. Brown has not shown an impediment
preventing him from timely raising these suppression arguments, and he has failed to
establish good cause to show why he did not file a second motion to suppress. Had Mr.
Brown raised the issue of good cause to the district court, the district court would not have
abused its discretion by finding no good cause. Rodriguez, ¶ 39, 435 P.3d at 411 (citing
United States v. Daniels, 803 F.3d 335, 352 (7th Cir. 2015)).
The district court did not err when it admitted Rule 404(b) evidence at trial.
[¶43] Mr. Brown next contends the district court abused its discretion under Rule 404(b)
by admitting text and Facebook messages between Mr. Brown and five individuals
purportedly regarding drug transactions. He argues the district court failed to admit the
messages for a proper purpose, did not meaningfully determine whether the admitted
messages were relevant to any proper non-propensity purpose, and improperly admitted
the messages only to show his propensity to act as a drug dealer. Mr. Brown further argues
any probative value was substantially outweighed by the danger of unfair prejudice.
[¶44] Because Mr. Brown filed a pretrial demand for notice of the State’s intent to
introduce Rule 404(b) evidence, our review is for an abuse of discretion. King v. State,
2023 WY 36, ¶ 26, 527 P.3d 1229, 1240 (Wyo. 2023). The district court’s ruling is entitled
to “considerable deference,” and this Court will not disturb that ruling so long as there is a
legitimate basis for the court’s decision. Mayhew v. State, 2019 WY 38, ¶ 23, 438 P.3d
617, 623 (Wyo. 2019). Mr. Brown bears the burden of showing an abuse of discretion. Id.
[¶45] W.R.E. 404(b) states,
Evidence of other crimes, wrongs, or acts is not admissible to
prove the character of a person in order to show that he acted
in conformity therewith. It may, however, be admissible for
other purposes, such as proof of motive, opportunity, intent,
preparation, plan, knowledge, identity, or absence of mistake
or accident, provided that upon request by the accused, the
prosecution in a criminal case shall provide reasonable notice
in advance of trial, or during trial if the court excuses pretrial
notice on good cause shown, of the general nature of any such
evidence it intends to introduce at trial.
10
Evidence of other acts may also be admitted “if it forms part of the history of the event or
serves to enhance the natural development of the facts.” Garrison v. State, 2018 WY 9, ¶
27, 409 P.3d 1209, 1217 (Wyo. 2018).
[¶46] When considering Rule 404(b) evidence, a district court must follow a mandatory
procedure and first consider the following factors:
(1) the evidence must be offered for a proper purpose; (2) the
evidence must be relevant; (3) the probative value of the
evidence must not be substantially outweighed by its potential
for unfair prejudice; and (4) upon request, the trial court must
instruct the jury that the similar acts evidence is to be
considered only for the proper purpose for which it was
admitted.
Anderson v. State, 2022 WY 119, ¶ 13, 517 P.3d 583, 588 (Wyo. 2022) (quoting Barrett v.
State, 2022 WY 64, ¶ 45, 509 P.3d 940, 949-50 (Wyo. 2022)). The district court must then
consider five additional factors in weighing the probative value of the evidence against its
potential for unfair prejudice:
1. How clear is it that the defendant committed the prior bad
act?
2. Does the defendant dispute the issue on which the state is
offering the prior bad acts evidence?
3. Is other evidence available?
4. Is the evidence unnecessarily cumulative?
5. How much time has elapsed between the charged crime and
the prior bad act?
Id. at ¶ 14, 517 P.3d at 589 (citation omitted). Finally, the court should then weigh the
following six factors against the probative value of the evidence:
1. The reprehensible nature of the prior bad act. The more
reprehensible the act, the more likely the jury will be tempted
to punish the defendant for the prior act.
11
2. The sympathetic character of the alleged victim of the prior
bad act. Again, the jury will be tempted to punish the defendant
for the prior act if the victim was especially vulnerable.
3. The similarity between the charged crime and the prior bad
act. The more similar the acts, the greater is the likelihood that
the jury will draw the improper inference that if the defendant
did it once, he probably did it again.
4. The comparative enormity of the charged crime and the prior
bad act. When the prior act is a more serious offense than the
charged crime, the introduction of that act will tend to place the
defendant in a different and unfavorable light.
5. The comparable relevance of the prior bad act to the proper

much more probative of bad character than it is of any
legitimate inference permitted by Rule 404(b).

[¶47] This Court does not repeat this analysis on appeal. Id. at ¶ 15, 517 P.3d at 589.
Instead, we review whether the district court properly applied the required framework, and
whether there is a legitimate basis for its decision. Id. “If the district court provided a
legitimate basis for its decision, we will not disturb it on appeal.” Id. (citing Barrett, ¶ 48,
509 P.3d at 50).
[¶48] Viewed as a whole, the district court’s ruling on the Rule 404(b) evidence at issue
demonstrates it conducted the required analysis. Although the court did not make express
findings on every factor under each category, it was not required to do so. See Gleason v.
State, 2002 WY 161, ¶ 28, 57 P.3d 332, 343 (Wyo. 2002) (stating “express findings on
each factor are not necessary[.]”). The court identified the governing Rule 404(b)
principles, evaluated the State’s proffers, and separately analyzed the relevance, probative
value, and prejudicial effect before ruling the text and Facebook messages were admissible.
[¶49] Mr. Brown asserts the district court admitted the text and Facebook messages
merely to show he had a propensity to sell drugs, and not for a proper purpose. We
disagree.
12
[¶50] According to the district court, the State offered evidence related to the text and
Facebook messages to show a “history of events and actions that form part of the history
of the actions charged, not for the purpose of creating forbidden inferences about the
character of Brown.” In addition, the district court found the evidence was proffered to
show agreement on the delivery of controlled substances in support of the possession with
intent to deliver charge.6 While the district court did not expressly state either of those
purposes were proper, a district court’s failure to expressly identify the purpose for
admission is “harmless error if the purpose for admitting the evidence is apparent from the
record and the decision to admit it is correct.” United States v. Hardwell, 80 F.3d 1471,
1488 (10th Cir. 1996). Here, it is apparent from the district court’s order that the purposes
for admitting the evidence were as the State contended. Specifically, the district court used
those purposes in its analysis of relevance, probative value, and prejudice under the
framework described above.7
[¶51] The decision to find this evidence was admissible for these purposes was also
proper. Evidence that “forms part of the history of the event or serves to enhance the
natural development of facts” are recognized categories of uncharged misconduct evidence
that can be admissible as exceptions under Rule 404(b). In addition, evidence explaining
the sequence of events leading to the charged offense, or placing the offense in context
serves a legitimate purpose because “events do not occur in a vacuum, and the jury has the
right to have the offense placed in its proper setting.” Anderson, ¶ 25, 517 P.3d at 591
(quoting Garrison, ¶ 27, 409 P.3d at 1217).
[¶52] The State charged Mr. Brown with possession of methamphetamine with intent to
deliver and conspiracy to deliver methamphetamine. The challenged messages contained
coded and other language regarding Mr. Brown potentially providing controlled substances
to the five individuals. The messages were admitted for the proper purpose of explaining
the history of Mr. Brown’s charged misconduct and enhancing the natural development of
facts. They also provided a sequence of events leading to the charged offense. That is,
they tended to establish Mr. Brown possessed drugs with an intent to distribute them, rather
than solely for his personal use.
[¶53] Mr. Brown next argues the messages were not relevant to the proper purpose
identified by the district court.
[¶54] Evidence is relevant if it has “any tendency to make the existence of any fact that is
of consequence to the determination of the action more probable or less probable than it

As noted earlier, Mr. Brown’s and Ms. Lascano’s cases were joined. The district court’s order
inadvertently transposes Ms. Lascano’s name for Mr. Brown’s twice in its analysis of Mr. Brown’s text and
Facebook messages, although it is clear that the district court is discussing Mr. Brown and his text and
Facebook messages.

Earlier in its order the district court found that blanket assertions that all of the evidence at issue was used
for the same proper purpose were, standing alone, insufficient.

would be without the evidence.” W.R.E. 401. Furthermore, we have said, evidence is
“always relevant if it tends to prove or disprove one of the elements of the crime charged.”
Hill v. State, 2016 WY 27, ¶ 30, 371 P.3d 553, 562 (Wyo. 2016) (citation omitted).
[¶55] The district court’s finding on relevance was that the proffered texts and Facebook
messages were relevant because they had the potential to demonstrate ongoing
participation in activities central to the charges. We conclude the district court had a
legitimate basis upon which to draw this conclusion. Specifically, the text and Facebook
message tended to show Mr. Brown’s knowledge of drug trafficking, his intent to
participate in those activities, and his ongoing involvement in such activities during the
same general time period as the charged offenses. They placed the charged conduct in
context by explaining the sequence of events leading to the offenses. The messages also
showed Mr. Brown had an ongoing scheme to distribute, which was also relevant to intent
and course of conduct. See Santistevan v. State, 2024 WY 17, ¶ 19, 542 P.3d 200, 206
(Wyo. 2024) (finding the district court did not rely solely on course of conduct exception
to admit evidence, but also to show it was an ongoing scheme or plan).
[¶56] Mr. Brown further argues the challenged messages were nevertheless improper
because they occurred months before the charged offenses and were not “inextricably
intertwined” with a single criminal episode. However, Rule 404(b) imposes no time limit
on other-acts evidence. See Hart v. State, 2002 WY 163, ¶ 22, 57 P.3d 348, 356 (Wyo.
2002) (“[T]here is no specific time limitation in determining remoteness of the similar
act.”). Remoteness is simply one factor bearing on relevance, and the district court
expressly considered the timing of the communications, observed they were within the
same general timeframe as the charged offenses,8 and concluded they remained relevant to
the “on-going scheme foundational to the charges herein.” That conclusion provided a
legitimate basis for finding the evidence relevant.
[¶57] Finally, Mr. Brown argues the district court failed to properly balance the probative
value of the messages against the danger of unfair prejudice. “When appellant claims the
testimony was unduly prejudicial under Rule 403, W.R.E., he must demonstrate that the
evidence had little or no probative value and that it was extremely inflammatory or
introduced for the purpose of inflaming the jury.” Garrison, ¶ 30, 409 P.3d at 1218
(quoting Law v. State, 2004 WY 111, ¶ 15, 98 P.3d 181, 187 (Wyo
