__________________________________________
Clerk
Justice Jim Regnier delivered the Opinion of the Court.

¶1 Defendant Mark Theodore Larson (Larson) was convicted by a jury in the Ninth

Judicial District Court, Pondera County, on one count of negligent homicide, a felony, and

one count each of the following misdemeanors: driving under the influence, speeding and

failure to wear a seatbelt. Larson appeals his convictions. We affirm.

¶2 The following issues are presented on appeal:

¶3 1. Whether the District Court erred in its ruling admitting the testimony of the State’s

blood alcohol expert.

¶4 2. Whether the District Court erred by granting the State’s motion in limine to

exclude evidence of the deceased victim’s blood alcohol concentration.

¶5 3. Whether the District Court erred by granting the State’s motion in limine to

exclude evidence of the erection of new highway signs at the accident scene.

¶6 4. Whether the District Court properly instructed the jury on the definition of

criminal negligence.

¶7 5. Whether the State provided sufficient evidence of impairment to support Larson’s

conviction for negligent homicide and driving under the influence.

¶8 6. Whether the State provided sufficient evidence to support Larson’s conviction for

exceeding the speed limit.

¶9 7. Whether Larson is entitled to a new trial under the doctrine of cumulative error.

PROCEDURAL AND FACTUAL BACKGROUND

¶10 Larson was involved in a one-vehicle rollover November 11, 2001, on a frontage road

north of Brady, Pondera County, that caused the death of Nicholas John Clare (Clare). The

2
particular stretch of roadway where the accident occurred involved a severe curve, narrow

shoulders and barrow ditches on both sides. Around 3:30 a.m., Larson drove his pickup

across the fog line and off the right shoulder of the road surface near the beginning of the

severe left curve. Larson pulled the pickup back onto the asphalt surface but overcorrected,

sending the pickup across the highway and into the left barrow ditch. Attempting to ride-out

the ditch, the pickup rolled over two and a quarter times, ejecting the three occupants,

Larson, Clare and Lynn Morgan (Morgan), who had not been wearing seatbelts. Larson and

Morgan escaped without serious injuries, but Clare sustained blunt-force trauma to the head

and died as a result of his injuries.

¶11 Emergency medical technicians from the Pondera Medical Center were notified of the

accident at 4:04 a.m. and arrived at the crash scene at approximately 4:16 a.m. The EMTs

treated the occupants at the scene, declaring Clare dead on arrival. Having determined Clare

deceased, the paramedics performed aid on Larson whom they feared had a spinal fracture.

The paramedics who treated Larson at the scene and in the ambulance smelled alcohol on

his breath, and Larson admitted to one of the EMTs he had been drinking. Montana

Highway Patrol Officer Noel Durham, who received Larson at the hospital, also stated he

smelled alcohol on Larson’s breath.

¶12 Montana Highway Patrol Officer, Jerril Ren, was notified of the accident at

approximately 4:04 a.m and arrived at the scene at about 4:40 a.m. When he arrived at the

scene, he found Clare’s body next to a green and silver full-sized Chevrolet pickup resting

on the driver’s side of the vehicle in the east ditch facing southwest. Officer Ren noticed

skid marks at the accident scene indicating Larson’s vehicle had drifted off the right side of

3
the roadway, overcorrected and continued across the highway into the east ditch. After

taking pictures at the scene, Officer Ren departed the crash scene and proceeded to the

Pondera Medical Center.

¶13 Officer Ren spoke with Larson at the Pondera Medical Center. When asked by

Officer Ren, Larson admitted he and the others had been drinking at various residences and

bars as well as in his vehicle in the Conrad and Dutton area earlier that evening. Larson

admitted he had consumed between ten and twelve drinks during the evening, including beer

and whiskey. Larson also recounted how he had been momentarily distracted during a

conversation with Clare and drifted off the right side of the roadway. Larson indicated he

tried to steer the vehicle back onto the roadway before overcorrecting and traversing across

the roadway and entering the ditch on the other side. Attempting to ride-out the ditch,

Larson stated he turned the wheels towards the skid when the vehicle flipped. A sample of

Larson’s blood was drawn at 5:43 a.m. and sent to the crime lab for analysis. The crime lab

reported Larson’s blood alcohol concentration was 0.12%.

¶14 Officers Ren and Durham investigated the cause of the wreck and took measurements

of the three tire marks on the highway in order to estimate Larson’s speed. The officers

arrived at speed estimates of 84 to 89 mph at the time Larson’s pickup crashed. The

estimates were later confirmed by Sergeant Brad Sangray of the Montana Highway Patrol,

who determined through his own investigation the pickup’s estimated speed was 83 mph.

This speed was also confirmed, though later recanted at trial, by Morgan who told officers

at the accident scene he believed Larson was traveling between 80 to 85 mph at the time of

the wreck. Sergeant Sangray determined the accident was caused by speed, inattentive

4
driving, alcohol influence and failure to wear seatbelts.

¶15 Estimates at trial by Larson’s expert, Dr. Denmen Lee, indicated Larson’s speed at

the time of the accident was between 63 to 71 mph with a standard deviation of plus or

minus 4 mph. Dr. Lee disputed the officer’s calculations, in particular, alleging they only

used three skid marks when the prevailing science required four. The officers’ estimates, Dr.

Lee testified, were too high and did not reflect Larson’s speed accurately.

¶16 The State filed an Information on November 27, 2001, charging Larson with one

count of negligent homicide, a felony, pursuant to § 45-5-104, MCA; one count of driving

under the influence of alcohol, a misdemeanor, pursuant to § 61-8-401, MCA; one count of

failing to wear a seatbelt, a misdemeanor, pursuant to § 61-13-103, MCA; and one count of

speeding, a misdemeanor, pursuant to § 61-8-303(1)(b), MCA.

¶17 Prior to trial, the State filed motions in limine seeking to exclude evidence of other

traffic accidents near the same location; evidence of the erection of new highway signs at the

location of the accident; and evidence of Clare’s blood alcohol concentration. Similarly,

Larson filed a motion in limine to exclude any evidence involving the “retrograde

extrapolation” of his blood alcohol concentration test administered after the accident.

Retrograde extrapolation is the use of a test administered after an event to determine a

person’s blood alcohol at an earlier time by adding on the average metabolic destruction of

alcohol during the period of delay.

¶18 On March 14, 2003, the District Court issued its ruling on the motions in limine. The

District Court denied the State’s request to exclude evidence of other traffic accidents but

granted the State’s request to prohibit evidence of new highway signs unless offered to rebut

5
or refute evidence from the State that it did not consider the site of the accident to be

dangerous. The District Court also granted the State’s request to exclude evidence of Clare’s

blood alcohol as well as Larson’s request to exclude any evidence regarding the retrograde

extrapolation results of the blood alcohol concentration test.

¶19 The trial began on March 17, 2003. The State’s evidence at trial showed during the

evening hours of November 10 and early morning hours of November 11, 2001, Larson and

two college friends, Morgan and Clare, were drinking in his vehicle and in various bars and

residences in the Conrad and Dutton area.

¶20 At about 3:30 a.m., Larson was driving his pickup at a high rate of speed south on the

frontage road between Conrad and Brady when it veered off the right shoulder of the road

surface near the beginning of a left curve. Larson pulled the pickup back onto the asphalt

surface but overcorrected, sending his pickup across the highway and into the ditch on the

left side of the highway. At that point, the car flipped multiple times, ejecting all three

passengers, who were not wearing seatbelts.

¶21 The State’s expert, Lynn Kurtz, of the state crime lab, testified analysis of Larson’s

blood sample taken three hours after the accident showed a blood alcohol concentration of

0.12%. Kurtz also testified concerning the effects of alcohol on an individual’s ability to

operate a motor vehicle, stating alcohol impairs an individual’s ability to drive.

¶22 Over Larson’s objections, Kurtz also discussed how an individual processes alcohol

in three phases, describing the intervals as “alcohol absorption phase,” “peak alcohol phase,”

and “elimination phase.” When posed with a hypothetical question about which of the three

phases a person would be in at the time of a BAC test, assuming the person quit drinking at

6
2:00 a.m., was in a wreck at 3:30 a.m., and was tested at 5:43 a.m, Kurtz testified an

individual in such a scenario would be in the elimination phase, having totally absorbed the

alcohol into his or her system earlier. Moreover, Kurtz stated a person’s peak alcohol level

would be reached sometime within a half hour to an hour and a half after the person stopped

consuming alcohol. Kurtz refused to ascribe a specific number to Larson’s blood alcohol

concentration at the time of the accident.

¶23 On cross-examination, Kurtz agreed with Larson’s counsel it was not scientifically

possible to state what Larson’s blood alcohol levels would have been two hours before the

test. Kurtz stated using the results of a delayed test to determine a person’s blood alcohol

at an earlier time by adding on the average metabolic destruction of alcohol during the period

of delay was against state crime lab policy. Kurtz testified he did not engage in this

retrograde extrapolation but, given the time intervals, he could state Larson would have been

in the elimination phase at 5:43 a.m., nearly four hours after the last consumption of alcohol.

¶24 At the conclusion of the trial but before deliberations, the parties submitted proposed

jury instructions to the District Court. During the settling of jury instructions, Larson

objected to the State’s Instruction 19 which defined criminal negligence as follows:

A person acts negligently with respect to the death of a human being or to a
circumstance when an act is done with a conscious disregard of the risk that
death of a human being will occur or that the circumstance exists or when the
person disregards a risk of causing the death of another human being which the
person should be aware that the result will occur or that the circumstance
exists.

The risk must be of a nature and degree that to disregard it involves a gross
deviation from the standard of conduct that a reasonable person would observe
in the actor’s situation. ‘Gross deviation’ means a deviation that is
considerably greater than lack of ordinary care.

7
Larson objected to the instruction on the grounds the word “consciously” should have been

inserted before the word “disregards” in defining criminal negligence. The court rejected

Larson’s objection, stating, “I believe the Court’s Instruction is the definition, as provided

by the Statute.”

¶25 After its deliberations, the jury returned verdicts of guilty on all counts. Judgment

was entered on April 25, 2003, convicting Larson to seven years in prison, all suspended

under certain terms and conditions. Larson appeals.

ISSUE ONE

¶26 Whether the District Court erred in its ruling admitting the testimony of the

State’s blood alcohol expert.

¶27 Larson argues the District Court abused its discretion when it permitted evidence

concerning his blood alcohol at trial. Larson maintains the District Court violated its own

order by allowing the State’s expert to offer an opinion Larson, at the time his blood draw

was taken, had reached and passed “peak alcohol.” Larson contends all evidence involving

retrograde extrapolation was prejudicial, against the State Crime Lab’s own policy and in

direct contravention of the District Court’s motion in limine.

¶28 The State counters its expert did not engage in back extrapolation because he did not

attempt to use the results of the delayed blood draw to specifically determine Larson’s blood

alcohol at an earlier time. The State maintains its expert stated only that, given the time

intervals, Larson would have been in the elimination phase after the accident.

¶29 Issues concerning the admissibility of evidence are within the discretion of the district

court. Cottrell v. Burlington Northern R. Co. (1993), 261 Mont. 296, 301, 863 P.2d 381,

8
384. “The trial court is vested with great latitude in ruling on the admissibility of expert

testimony.” Cash v. Otis Elevator Co. (1984), 210 Mont. 319, 332, 684 P.2d 1041, 1048.

A district court has broad discretion to determine whether evidence is relevant and

admissible, and absent an abuse of discretion, this Court will not overturn that court’s ruling.

State v. Hamilton, 2002 MT 263, ¶ 10, 312 Mont. 249, ¶ 10, 59 P.3d 387, ¶ 10. The test for

abuse of discretion is whether the trial court acted arbitrarily without employment of

conscientious judgment or exceeded the bounds of reason resulting in substantial injustice.

State v. Brasda, 2003 MT 374, ¶ 14, 319 Mont. 146, ¶ 14, 82 P.3d 922, ¶ 14.

¶30 We conclude the District Court did not abuse its discretion when it admitted testimony

by the State’s expert witness regarding Larson’s blood alcohol. The District Court correctly

recognized the distinction between “elimination phase” testimony and “retrograde

extrapolation” testimony, admitting the former and prohibiting the latter. Retrograde

extrapolation is a method of estimating a person’s blood alcohol level at a specified time by

using the person’s known blood alcohol content at a later time. Kurtz did not assign a

definitive number to Larson’s blood alcohol at the time of the accident, but instead stated his

opinion Larson would have reached the peak alcohol phase earlier in the evening and been

in the elimination phase at the time of the blood draw. Furthermore, the results of the blood

test, which indicated Larson’s blood alcohol was at 0.12%, when considered in combination

with Kurtz’s foundational testimony that an individual’s blood alcohol usually peaks within

a half hour to an hour and a half following consumption, tended to make it more probable

Larson was in the elimination phase at the time the blood test was taken. Although this

necessarily assumes his alcohol levels were higher before the time the test was conducted,

9
Kurtz did not engage in retrograde extrapolation. That is, Kurtz did not give an opinion as

to Larson’s blood alcohol level at the time of the accident. By failing to engage in retrograde

extrapolation, Kurtz did not violate state crime lab policy. Accordingly, we hold the District

Court did not abuse its discretion when it admitted Kurtz’s testimony regarding Larson’s

blood alcohol.

ISSUE TWO

¶31 Whether the District Court erred by granting the State’s motion in limine to

exclude evidence of the deceased victim’s blood alcohol concentration.

¶32 Larson argues the District Court erred when it prohibited Larson from presenting

evidence of Clare’s blood alcohol at trial. Larson maintains evidence comparing Clare’s

blood alcohol at the time of the accident with Larson’s two hours after the crash would have

supported prospective testimony about the drinking activities on the evening of the accident

as well as countered the State’s expert witness testimony regarding Larson’s alleged

impairment.

¶33 The State counters Clare’s blood alcohol concentration level was not relevant or

probative of Larson’s blood alcohol or the extent of Larson’s impairment at the time of the

accident. The State maintains testimony at trial did not suggest Larson and Clare consumed

alcohol in exactly the same amounts and times nor did it show similarities between the men’s

body weight, stomach contents, and elimination rate.

¶34 The authority to grant or deny a motion in limine “rests in the inherent power of the

court to admit or exclude evidence and to take such precautions as are necessary to afford

a fair trial.” State v. Krause, 2002 MT 63, ¶ 32, 309 Mont. 174, ¶ 32, 44 P.3d 493, ¶ 32

10
(citations omitted). Therefore, we will not overturn a district court’s grant or denial of a

motion in limine absent an abuse of discretion. Krause, ¶ 32. The test for abuse of

discretion is whether the district court acted arbitrarily without conscientious judgment or

exceeded the bounds of reason. State v. Richardson, 2000 MT 72, ¶ 24, 299 Mont. 102, ¶

24, 997 P.2d 786, ¶ 24.

¶35 Rule 401, M.R.Evid., defines relevant evidence as “evidence having 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 would be without the evidence.” Rule 402, M.R.Evid.,

provides that relevant evidence is generally admissible. However, Rule 403, M.R.Evid.,

creates an exception to Rule 402's general admissibility standard, providing, “[e]vidence may

be excluded if its probative value is substantially outweighed by the danger of unfair

prejudice, confusion of the issues, or misleading the jury . . . .”

¶36 We conclude the District Court did not abuse its discretion when it granted the State’s

motion in limine to exclude evidence of Clare’s blood alcohol concentration. Although the

District Court’s order granting the State’s motion did not set forth its reasons for excluding

evidence of Clare’s blood alcohol level, it presumably agreed with the State the blood

alcohol concentration results and evidence of Clare’s alcohol consumption were irrelevant.

Indeed, although Clare’s autopsy results indicated his blood alcohol was less than 0.10%, it

would not have changed following the collision, as he died instantaneously. Further, there

is no evidence to suggest the two men consumed alcohol in exactly the same amounts and

at the same times. As such, even if the evidence had probative value, the probative value

would be outweighed by the unfair prejudice resulting from its admission. Clare’s actions

11
and activities were not on trial. Finally, this Court has determined the State’s expert did not

engage in retrograde extrapolation, thus, evidence of Clare’s blood alcohol concentration is

not necessary to counter Kurtz’s testimony regarding Larson’s impairment. Accordingly, we

hold the District Court did not abuse its discretion when it granted the State’s motion to

exclude Clare’s blood alcohol concentration results.

ISSUE THREE

¶37 Whether the District Court erred by granting the State’s motion in limine to

exclude evidence of the erection of new highway signs at the accident scene.

¶38 Larson argues the District Court erred when it prohibited him from producing

evidence at trial indicating new road signs had been erected at the accident scene following

the crash. Larson maintains the absence of adequate warning signs ahead of the curve where

the accident took place established the roadway’s danger and partially vitiated his

negligence. Further, the evidence of new signage was not offered to prove negligence or

culpable conduct of the State, but rather to show the roadway was more dangerous because

of the absence of proper signage.

¶39 The State counters the District Court did not abuse its discretion by excluding

evidence of highway signs erected at the scene following the accident. The State maintains

the District Court’s order prohibited evidence of new highway signs unless offered to rebut

or refute evidence from the State that it did not consider the site of the accident to be

dangerous. The State argues it conceded the roadway presented a risk to an inattentive driver

and thus evidence of signage was properly prohibited.

¶40 As stated above, the authority to grant or deny a motion in limine “rests in the inherent

12
power of the court to admit or exclude evidence and to take such precautions as are

necessary to afford a fair trial.” Krause, ¶ 32 (citations omitted). Therefore, we will not

overturn a district court’s grant or denial of a motion in limine absent an abuse of discretion.

Krause, ¶ 32. The test for abuse of discretion is whether the district court acted arbitrarily

without conscientious judgment or exceeded the bounds of reason. Richardson, ¶ 24.

¶41 We conclude the District Court did not abuse its discretion when it granted the State’s

motion in limine to exclude evidence of highway signs erected at the scene following the

accident. The District Court’s order stated evidence of highway signs would only be

admitted if offered to rebut or refute testimony or evidence from the State it did not consider

the site of the accident to be dangerous. In this case, the State did not dispute, either by

direct presentation of evidence or in argument, the highway at the location of the crash

presented a risk to an inattentive driver. Although Larson elicited on cross-examination an

admission from Officer Durham he thought the road was not dangerous, the District Court

indicated to Larson its reluctance to allow further testimony into Durham’s opinion on a

topic which the court had prohibited. Further, Larson was permitted to fully present his

theory the frontage road in question was a dangerous highway, chronicling a litany of other

motor vehicle accidents, including injuries and fatalities that occurred near the accident site.

Evidence of any changes in the signage subsequent to the accident would have substantiated

proof already offered at trial. Accordingly, we hold the District Court did not abuse its

discretion when it granted the State’s motion to exclude evidence of signs erected on the

highway after the accident.

13
 ISSUE FOUR

¶42 Whether the District Court properly instructed the jury on the definition of

criminal negligence.

¶43 Larson argues the District Court erred when it lowered the standard of proof required

under the statutory scheme defining criminal negligence. Larson maintains the instruction

for criminal negligence given to the jury should have included the word “consciously” as it

related to the individual’s disregard for a known risk. Larson contends by omitting the

modifying adverb “consciously” before the word “disregards,” the District Court lowered the

standard of proof as required under the Criminal Code.

¶44 The State counters the District Court properly instructed the jury on the definition of

criminal negligence. The State asserts the existing statutory definition given to the jury

provided an adequate means of distinguishing criminal negligence from ordinary negligence.

The State contends the instruction given to the jury made clear the standard on which to

judge Larson’s disregard of the risk involved as well as his gross deviation from a reasonable

standard of conduct.

¶45 A person commits negligent homicide if the person negligently causes the death of

another human being. Section 45-5-104, MCA. A person acts negligently with respect to

a result or circumstance, “when the person consciously disregards a risk that the result will

occur or that the circumstance exists or when the person disregards a risk of which the

person should be aware that the result will occur or the circumstance exists.” Section 45-2-

101(42), MCA. Further, the risk “must be of a nature and degree that to disregard it involves

a gross deviation from the standard of conduct that a reasonable person would observe in the

14
actor’s situation.” The term “gross deviation” is defined by the statute as meaning “a

deviation that is considerably greater than lack of ordinary care.”

¶46 This Court has previously decided mental state is not at issue in negligent homicide

cases. State v. Gould (1985), 216 Mont. 455, 477, 704 P.2d 20, 34. In Gould, we held the

defendant’s proposed instruction referred improperly to the necessity of acting with the

mental state of “consciously” as an element of the offense of negligent homicide. We

deemed such instruction improper. Similarly, Larson’s proposed instruction included the

term “consciously,” as used in § 45-2-101(42), MCA, to define criminal negligence. Unlike

deliberate homicide however, which requires the offense be committed purposely or

knowingly, negligent homicide does not require such purpose and knowledge. Negligent

homicide only requires a gross deviation from a reasonable standard of care. State v.

Kirkaldie (1978), 179 Mont. 283, 292, 587 P.2d 1298, 1304. Further, we have held criminal

negligence can arise as a result of intoxication. Kirkaldie, 179 Mont. at 292, 587 P.2d at

1304. Larson’s mental state at the time he was driving his car is not at issue. Instead, the

issue is whether the driving of a car while intoxicated was a gross deviation from the

standard of reasonable care. It is difficult to imagine that conduct, which included drinking

both beer and whiskey over many hours, disregarding the prevailing notion that drinking and

driving is dangerous, and then getting behind the wheel of a vehicle and driving down an

isolated county road at a speed in excess of the speed limit, could not be classed as a gross

deviation that is considerably greater than the lack of ordinary care.

¶47 The State’s proposed instruction stated, in part:

A person acts negligently with respect to the death of a human being when an

15
 act is done with conscious disregard of the risk that death of a human occur,
or when the person disregards a risk which the person should be aware that the
death of a human being will occur.

Larson objected to this instruction on the ground the Court was effectively lowering the

standard of proof as required by the framers of the criminal code. In answer to Larson’s

objection on the proposed instruction, the District Court stated, “I believe the Court’s

Instruction is the definition, as provided by the Statute.” We agree.

¶48 We hold the jury was adequately instructed on negligence and the elements of the

offense charged. Under the given instructions, if the jury believed Larson’s account of the

accident, they could have found in his favor. However, it was the jury’s duty to determine

which account of the accident, the State’s or Larson’s, they believed more credible and

worthy of belief. State v. Lewis (1976), 169 Mont. 290, 294, 546 P.2d 518, 520. Where the

jury is adequately instructed, no error occurs in refusing a proposed instruction which is

already covered. Kirkaldie, 179 Mont. at 293, 587 P.2d at 1304. Here, the jury was fully

instructed and Larson had a full opportunity to argue the merits of his defense. Accordingly,

we hold the District Court properly instructed the jury on the definition of criminal

negligence.

ISSUE FIVE

¶49 Whether the State provided sufficient evidence of impairment to support Larson’s

conviction for negligent homicide and driving under the influence.

¶50 Larson argues the State’s evidence at trial was insufficient to support the jury’s

determination he was impaired by alcohol at the time of the accident. Larson maintains the

inference of impairment resulting from his 0.12% blood alcohol concentration was rebutted

16
by other evidence indicating the accident was caused by a momentary lapse of attention

while driving on a dangerous road.

¶51 The State responds the evidence presented at trial of Larson’s impairment was

sufficient to support his negligent homicide and driving under the influence convictions. The

State maintains it presented evidence including Larson’s consumption of alcohol, the high

rate of speed he was driving, testimony of witnesses indicating he was intoxicated as well

as his blood alcohol concentration of 0.12% which sufficiently supported the jury’s verdict.

¶52 This Court reviews a question concerning the sufficiency of the evidence to determine

whether, after reviewing the evidence in a light most favorable to the prosecution, any

rational trier of fact could have found the essential elements of the crime beyond a

reasonable doubt. State v. York, 2003 MT 349, ¶ 10, 318 Mont. 511, ¶ 10, 81 P.3d 1277, ¶

10. We review the jury’s verdict only to determine whether it is supported by sufficient

evidence, not to determine whether there was sufficient evidence to support a different

verdict. State v. Sattler, 1998 MT 57, ¶ 60, 288 Mont. 79, ¶ 60, 956 P.2d 54, ¶ 60.

¶53 “The credibility of witnesses and the weight given to their testimony are determined

by the trier of fact, and disputed questions of fact and credibility will not be disturbed on

appeal.” State v. Bauer, 2002 MT 7, ¶ 15, 308 Mont. 99, ¶ 15, 39 P.3d 689, ¶ 15. Only in

those rare cases where the story told is so inherently improbable or is so nullified by material

self-contradiction that no fair-minded person could believe it may we say no firm foundation

exists for the verdict based on it. Bauer, ¶ 15.

¶54 We conclude the State provided sufficient evidence of Larson’s impairment to support

Larson’s conviction for negligent homicide and driving under the influence. Here, the State

17
presented evidence Larson drank a substantial amount of alcohol during the evening and

morning hours before the accident. Further, Larson admitted to EMTs and officers at the

hospital he had consumed a considerable amount of alcohol. The State also showed Larson

drove his pickup at a high rate of speed off the shoulder of the highway, causing the pickup

to roll over and eject all three passengers. The State’s expert witness testified the driving

ability of anyone with a blood alcohol concentration of 0.08% or more is impaired or

diminished. The jury in this case also heard testimony Larson’s blood alcohol concentration

was 0.12% two hours after the accident and four hours after he had stopped drinking.

¶55 We cannot know precisely why or how the jury reached its decision to convict Larson.

We only know Larson presented his theory that other mitigating factors may have caused the

accident, and the jury apparently rejected it. We hold, therefore, sufficient evidence exists

to support Larson’s convictions.

ISSUE SIX

¶56 Whether the State provided sufficient evidence to support Larson’s conviction for

exceeding the speed limit.

¶57 Larson argues the State failed to present sufficient evidence to support a conviction

of the offense of speeding. Larson maintains his own estimate at the time of the accident was

60 to 65 mph which was confirmed by Morgan at trial and bolstered by his expert witness

who calculated a speed between 63 and 71 mph. Larson contends the higher estimates of the

investigating officers were based upon flawed measurements which failed to prove, beyond

a reasonable doubt, his speed was excessive.

¶58 The State counters the evidence presented at trial of Larson’s speed was sufficient to

18
support the jury’s verdict. The State contends the jury had sufficient evidence from two

police accident reconstructionists as well as Morgan’s statements shortly after the accident

to conclude Larson violated the speed restriction for nighttime driving on the frontage road.

¶59 As discussed above, the standard of review for a claim of insufficiency of the

evidence is whether any rational trier of fact, viewing the evidence in a light most favorable

to the prosecution, could have found the essential elements of the offense beyond a

reasonable doubt. York, ¶ 10. Further, credibility of witnesses and the weight to be given

to their testimony are to be determined by the trier of fact, and disputed questions of fact and

credibility will not be disturbed on appeal. State v. Ahmed (1996), 278 Mont. 200, 212, 924

P.2d 679, 686. The trier of fact is not required to blindly accept the defendant’s version of

the facts. State v. Brogan (1993), 261 Mont. 79, 87, 862 P.2d 19, 24. Moreover, “[i]f events

are capable of different interpretations, the trier of fact determines which is most

reasonable.” Brogan, 261 Mont. at 87, 862 P.2d at 24.

¶60 The jury was presented with evidence the nighttime speed limit for a non-interstate

public highway in Montana is 65 mph. Larson’s speed was estimated to be between 84 to

89 mph or 63 to 71 mph by the State and Larson’s experts respectively. Further, the jury

heard Morgan contradict his earlier statements to police he believed Larson was traveling

between 80 to 85 mph on the night of the accident.

¶61 Again, we cannot know precisely why or how the jury reached its decision to convict

Larson. Based on the evidence presented to the jury in this case however, a rational trier of

fact could have found Larson had been driving in excess of the posted speed limit. We

therefore affirm Larson’s conviction on that count.

¶62 Whether Larson is entitled to a new trial under the doctrine of cumulative error.

¶63 Larson argues he was denied a fair trial under the doctrine of cumulative error.

Larson contends he was denied a fair trial and is therefore entitled to a new trial due to the

cumulative errors he has argued in this appeal.

¶64 The State counters the District Court’s rulings fall well within the broad discretion of

the court to determine the relevance and admissibility of evidence to instruct the jury.

¶65 The doctrine of cumulative error requires reversal of a conviction where a number of

errors, taken together, prejudiced a defendant’s right to a fair trial. State v. Ottwell (1989),

239 Mont. 150, 157, 779 P.2d 500, 504. Under this doctrine, once such accumulated errors

are identified as having prejudiced a defendant’s right to a fair trial, reversal is required.

Enright, ¶ 34. However, the existence of prejudice must be established by the defendant, as

“mere allegations of error without proof of prejudice are inadequate to satisfy the doctrine.”

State v. Campbell (1990), 241 Mont. 323, 329, 787 P.2d 329, 333.

¶66 We find no grounds to apply the doctrine of cumulative error in this case. This Court

has carefully reviewed the issues presented by appellants. We find no prejudice in this case

that would warrant reversal. Further, we find no abuse of judicial discretion in the District

Court's evidentiary rulings. Moreover, we hold, there was sufficient evidence for the jury to

convict on the charges against Larson. Finally, inasmuch as none of the evidentiary rulings

cited by Larson was error, this Court finds no grounds to apply the doctrine of cumulative

error.

¶67 For the foregoing reasons, the judgment of the District Court is affirmed.
