__________________________________________ Clerk Justice Laurie McKinnon delivered the Opinion of the Court.

¶1 On December 11, 2023, Zachary T. Ellis (Ellis) was convicted of misdemeanor

Driving Under the Influence (DUI), third offense, in violation of § 61-8-1002(1)(a), MCA,

following a bench trial in Gallatin County Justice Court. Prior to trial, the Justice Court

denied Ellis’s motions to suppress evidence which alleged a lack of particularized

suspicion justifying the investigation, an improper search and seizure, and a violation of

Miranda. Ellis appealed the denials of his motions to the Eighteenth Judicial District

Court, Gallatin County. The District Court affirmed the Justice Court and upheld Ellis’s

conviction. Ellis now appeals to this court. We affirm.

¶2 We restate the issues on appeal as follows:

Issue One: Whether there was particularized suspicion to investigate Ellis for driving under the influence.

Issue Two: Whether there was an unlawful search and seizure.

Issue Three: Whether there was a custodial interrogation that required a Miranda advisement when Ellis made statements to law enforcement.

Issue Four: Whether this Court can address Ellis’s unpreserved claim that the results of his blood test were admitted without a sufficient foundation.

Issue Five: Whether there was sufficient evidence to convict Ellis of driving under the influence.

FACTUAL AND PROCEDURAL BACKGROUND

¶3 On March 2, 2023, at around 5:00 p.m., Montana Highway Patrol Trooper Alex

Becken (Trooper Becken) was dispatched to a single vehicle crash on Huffine Lane near

Love Lane in Gallatin County. An individual called 911 after witnessing a black Jeep

Liberty go into a ditch, hit a sign that broke out the back windows, and then drive away.

2 The driver told the caller, “I’m fine, I just passed out, I fell asleep for a second.” A second

caller also saw the Jeep Liberty hit the sign and go into the ditch. Both callers later testified

at trial that on the day of the crash road conditions were dry.

¶4 Dispatch provided Trooper Becken with the description of the vehicle and the

vehicle’s license plate number. Trooper Becken began looking for the Jeep in the reported

crash area and observed two traffic signs down and tire marks leading into a nearby ditch.

The license plate was registered to Ellis’s wife, so Trooper Becken proceeded to Ellis’s

address.

¶5 Sergeant Brian Taylor (Sergeant Taylor) of the Gallatin County Sheriff’s Office was

also dispatched to the accident and learned the direction the Jeep was headed. He drove

towards the Ellis residence located in a subdivision near Belgrade, Montana. Sergeant

Taylor observed a male walking away from the Jeep, which was parked in the street, and

up the driveway. Trooper Becken arrived on the scene around the same time. The Jeep at

the residence matched the plate number provided by dispatch.

¶6 The Jeep had damage to the front bumper and a broken window on the rear driver’s

side. The male identified himself as Zachary Ellis. Ellis had a dazed expression, excessive

mucus on his sleeve, and watery, bloodshot eyes. When asked by Sergeant Taylor where

he was coming from, Ellis disclosed “[The hardware store] . . . I was on Huffine.” Trooper

Becken asked Ellis what happened to the front of the Jeep and Ellis responded, “I passed

out.” Soon after, Sergeant Taylor asked Ellis what he purchased at the hardware store and

3 Ellis responded that he bought “some duster.” 1 Sergeant Taylor further inquired because

he saw “a bunch of snot” on Ellis’s shirt. He then asked Ellis whether he had sniffed the

duster. “I did try that. And . . . that is not good.” Sergeant Taylor asked, “[Did you] try

that while you were driving?” Ellis responded, “apparently.” After stepping away,

Trooper Becken returned to Sergeant Taylor and Ellis when Ellis stated, “that’s probably

what made me pass out.” Trooper Becken subsequently administered Standardized Field

Sobriety Tests, (SFSTs).

¶7 Trooper Becken had Ellis perform the Horizontal Gaze Nystagmus (HGN) test,

walk and turn test, the one leg stand test, and the Romberg test. Ellis showed clues of

impairment on a majority of the tests. Additionally, Trooper Becken observed Ellis had

heavy eyelids and body tremors during testing.

¶8 After officers asked if Ellis still had the can of Dust-Off, Ellis provided the can he

consumed. Ellis had placed the can of Dust-Off in the back seat of a sedan parked in his

driveway. While holding the can, Trooper Brecken noted the Dust-Off can was nine-tenths

empty. Ellis confirmed he was the one driving the Jeep and that he had not consumed any

Dust-Off or alcohol after the crash.

¶9 Ellis provided a preliminary breath sample that indicated he had no alcohol in his

system. Based on his observations and conversation with Ellis, Trooper Becken arrested

1 Duster, generally used for dusting off electronics, can result in impairment if ingested. Possible impairment includes confusion, slurred speech, and unconsciousness. At trial, both Sergeant Taylor and Trooper Becken testified about the impact of ingesting Dust-Off. Dust-Off contains difluoroethane (DFE), which typically produces a short high before the person who huffed it passes out. 4 Ellis for DUI. Ellis consented to providing a blood sample and completed a blood draw at

Bozeman Health Deaconess Hospital with Trooper Becken in attendance. Ellis was

subsequently booked into the Gallatin County Detention Center. The toxicology report

detected DFE in Ellis’s system.

¶10 On May 17, 2023, Ellis filed motions to suppress evidence asserting a lack of

particularized suspicion, an unlawful search and seizure, and a violation of Miranda. On

August 14, 2023, the Justice Court denied his motions to suppress. A bench trial was held

on December 11, 2023. In its case-in-chief, the State called forensic toxicologist Scott

Larson (Larson). The State moved to admit Ellis’s toxicology report through Larson and

Ellis objected on grounds of foundation. The Justice Court overruled the objection,

admitted the toxicology report, and found Ellis guilty of DUI on the same day. Ellis was

sentenced on December 20, 2023, to one year in jail with all but forty-five days suspended.

¶11 Ellis filed a notice of appeal in the Gallatin County District Court on January 12,

2024. The District Court affirmed his conviction and the denial of his motions to suppress

on October 3, 2024. It reasoned that law enforcement had ample particularized suspicion

to investigate the accident and the investigation developed into particularized suspicion for

a DUI.
