delivered the Opinion of the Court.
¶1 Steven Leo Matz (Matz) appeals from the verdict and judgment entered by the Thirteenth Judicial District Court, Yellowstone County, finding him guilty of felony aggravated assault and enhancing his sentence for that offense with an additional five years pursuant to § 46-18-221, MCA, based upon the finding that he used a weapon in the commission of the offense. We affirm.
¶2 We consider the following issues on appeal:
¶3 (1) Did the District Court err in denying Matz’s proposed jury instruction which would have required the State to prove that Matz did not act with justifiable use of force?
¶4 (2) Did Matz’s sentence enhancement for using a weapon violate *203 double jeopardy where his underlying conviction was for aggravated assault?
¶5 (3) Did the District Court err by giving a jury instruction that did not distinguish which form of serious bodily injury was being alleged?
¶6 (4) Did the District Court abuse its discretion by excluding evidence that the alleged victim had marijuana and a marijuana pipe in his pocket at the time of the altercation?
FACTUAL AND PROCEDURAL BACKGROUND
¶7 Steve Andersen (Andersen) and his wife, Amber Andersen (Amber), managed the Village Inn Pizza Parlor (Village Inn) in Billings, Montana. On the night of May 30, 2004, at approximately ten o’ clock in the evening, while taking a break from cleaning, Andersen noticed an individual on a bicycle cut through the parking lot, which was situated behind the restaurant. Knowing that there was only one way out of the parking lot, Andersen, joined by Amber, waited for the individual to ride back out. The individual, who turned out to be Matz, was riding his bicycle for exercise and in search of neighborhood dumpsters. Matz frequented dumpsters behind neighborhood pizza restaurants to recover discarded pizza, which he fed to his neighbor’s dogs.
¶8 Andersen and Amber, after waiting a minute or two, walked out to the parking lot and found Matz astride his bicycle while holding up the lid of the dumpster and perusing its contents. Andersen told Matz that he was on private property, to get out of the dumpster, and threatened to call the police. Matz indicated that he had a right to be there because the dumpster was public domain. Andersen issued another warning for Matz to leave the property and requested Amber to call the police, but the testimony about what occurred thereafter was conflicted.
¶9 A business videotape disclosed the parties’ initial meeting but did not capture the following altercation between Andersen and Matz. Matz testified that Andersen was belligerent and, as Matz rode his bicycle past Andersen to depart the premises, Andersen attacked him and knocked him off his bicycle and onto his back. Being susceptible to a shoulder injury and afraid he would be kicked in his shoulder, Matz testified that he pulled a gun he was carrying to protect himself, explaining that he is a licensed firearm dealer and that he carried the gun to defend himself while riding his bicycle in the evening. In contrast, Andersen testified that, after telling Amber to call the police, Matz began taunting Andersen while Andersen implored Matz to *204 leave. Matz responded by riding his bicycle over to within some two and a half feet of Andersen, pulling the gun from his pocket, and asking, “What do you think of this, tough guy?”
¶10 Seeing a gun pointed at his head, Andersen grabbed it with both of his hands in an effort to take it away. Struggling, both men fell to the ground. Matz pushed the gun barrel into Andersen’s side, while Andersen tried to point it away from his body. During the struggle Matz fired the gun twice, with one shot penetrating Andersen’s stomach and the other grazing his arm, but this did not end the battle. Hearing the gunshots, Amber ran outside and, seeing Matz on top of her husband, jumped onto Matz’s back and began choking him in an effort to remove him from Andersen. When Andersen yelled for Amber to grab the gun, Amber reached around the back of Matz and grabbed the four hands that were already clutching the gun, and all three of the parties struggled to control the gun. When, during the mélée, Amber noticed that the gun had become pointed toward Matz beneath her, and thinking that her husband may have been mortally wounded, she unsuccessfully attempted to discharge the firearm into Matz. Quickly responding police officers found the parties thus engaged and broke up the struggle.
¶11 The State filed its information charging Matz with aggravated assault. A jury trial was held which ended with Matz moving for and being granted a mistrial. A second trial in January 2005 resulted in a conviction. Prior to sentencing, Matz filed a “motion to strike and dismiss claim for weapon enhancement penalty,” seeking to deny the State’s request for a sentence enhancement, which the State had first asserted in the information. The District Court denied this motion, and Matz was sentenced to fifteen years in the Montana State Prison and an additional five years pursuant to § 46-18-221, MCA, because he was found to have used a weapon while engaged in the commission of the underlying offense of aggravated assault. Matz appeals.
DISCUSSION
¶12 (1) Did the District Court err in denying Matz’s proposed jury instruction which would have required the State to prove that Matz did not act with justifiable use of force?
¶13 ‘We review claims of instructional error in a criminal case to determine whether the jury instructions, as a whole, fully and fairly instruct the jury on the law applicable to the case.”
State v. DuBray,
¶14 Matz’s proposed jury instruction stated: “You are instructed [that] the Defendant, Steven Leo Matz, is not required to prove self-defense or justification. The State is required to prove beyond a reasonable doubt that justification or self-defense does not exist in this case.” Matz first argues that the District Court erred when it refused this proposed instruction because requiring a defendant to bear the burden of proof is unconstitutional. He argues it is only logical that when there are issues of self-defense, as here, the State must be required to prove beyond a reasonable doubt that justification or self-defense does not exist. Matz asserts this Court has not expressly overturned
State v. Azure,
¶15 The State sirgues that while Matz may be correct that this Court has not expressly overruled its decision in
Azure,
its applicability has certainly been called into question and cannot stand beside more recent cases, such as
State v. Daniels,
From these cases the true rule can be drawn: The State has the burden of proving beyond a reasonable doubt every element of the offense charged, or any lesser-included crime within such charge; the defendant if he raises an affirmative defense has the burden of producing sufficient evidence on the issue to raise a reasonable doubt of his guilt....
Daniels,
¶16 We agree with the State that
Azure’s
statement, quoted above,
*206
approving a jury instruction which placed the burden upon the State to establish the absence of justification for use of force, is no longer good law. Indeed, we have previously explained that this was the effect of our holding in
Daniels.
In
State ex rel. Kuntz v. Thirteenth Jud. Dist.,
¶17 Matz raised justifiable use of force as his affirmative defense to the shooting. Therefore, it was properly and constitutionally Matz’s burden at trial to produce sufficient evidence to raise a reasonable doubt of his guilt based on his justifiable use of force defense, and the State was not obligated to prove that Matz did not act with such justification.
Daniels,
¶18 (2) Did Matz’s sentence enhancement for using a weapon violate double jeopardy where his underlying conviction was for aggravated assault?
¶19 This Court reviews a district court’s imposition of sentence for legality. When the issue concerns “whether the district court violated the defendant’s constitutional rights at sentencing, the question is a matter of law which we review
de novo
to determine whether the district court’s interpretation of the law is correct.”
State v. Mason,
¶20 Matz argues that his sentence of fifteen years for aggravated assault and the sentence enhancement of five years for use of a weapon during the commission of the aggravated assault is in violation of the prohibition against double jeopardy found at Article II, Section 25, of the Montana Constitution as interpreted in
State v. Guillaume,
¶21 The State argues that the use of a weapon is not an element of aggravated assault as charged against Matz, thus allowing Matz’s sentence to be enhanced for using a weapon. The State contends that application of the weapon enhancement statute to a conviction in which the underlying offense does not require proof of use of a weapon does not constitute a double jeopardy violation, citing
State v. Keith,
¶22 Montana’s weapon enhancement statute, § 46-18-221(1), MCA, provides that:
a person who has been found guilty of any offense, other than an offense in which the use of a weapon is an element of the offense, and who, while engaged in the commission of the offense, knowingly displayed, brandished, or otherwise used a firearm, destructive device, as defined in 45-8-332(1), or other dangerous weapon shall, in addition to the punishment provided for the commission of the underlying offense, be sentenced to a term of imprisonment in the state prison of not less than 2 years or more than 10 years, except as provided in 46-18-222.
¶23 This Court ruled in Guillaume, ¶ 16, that application of the weapon enhancement to an offense that itself requires proof of the use of a weapon violates Montana’s constitutional protection against double jeopardy. A double jeopardy analysis under Guillaume is based upon the statutory definition of the underlying offense, i.e., whether one of the elements of the offense requires proof of the use of a weapon. See Keith, ¶ 39.
*208 ¶24 Matz was charged of aggravated assault under § 45-5-202(1), MCA, which requires that an individual “purposely or knowingly causes serious bodily injury to another.” Pursuant thereto, the jury was directed in Instruction No. 13 that: “[t]o convict the Defendant of aggravated assault, the State must prove the following elements: (1) [t]hat the Defendant caused serious bodily injury to Steve Andersen; and (2) [t]hat the Defendant acted purposely and knowingly.” Then, the jury was further instructed, in Instruction No. 29, regarding the need to enter a separate finding regarding Matz’s use of a weapon:
[t]he State has alleged that in committing the offense of Aggravated Assault, the Defendant used a firearm or dangerous weapon. Whether the Defendant used a firearm or dangerous weapon in the commission of the offense for which the Defendant is being tried must be proved by the State by proof beyond a reasonable doubt. This is a separate finding by you, independent of the issue of whether the Defendant is guilty of the offense of Aggravated Assault. You need not find the Defendant used a firearm or dangerous weapon unless you first determine beyond a reasonable doubt that the Defendant committed the offense of Aggravated Assault. [Emphasis added.]
¶25 Matz’s use of a weapon was not an element of the offense of aggravated assault. The jury was instructed to make an additional, “separate finding,” which was used by the District Court to impose the sentence enhancement. Thus, it cannot be said that Matz received multiple punishments for the same act or crime.
¶26 According to the analysis required under our case law, it is clear that the District Court did not err in enhancing Matz’s sentence for use of a weapon where he was found guilty of aggravated assault under § 45-5-202, MCA, and was separately found by the jury to have used a weapon in the commission of that offense. Accordingly, the application of the weapon enhancement statute to Matz’s sentence for aggravated assault did not subject Matz to a punishment in violation of the double jeopardy provision of Article II, Section 25, of the Montana Constitution.
¶27 (3) Did the District Court err by giving a jury instruction that did not distinguish which form of serious bodily injury was being alleged?
¶28 We review a jury instruction in a criminal case to see whether the instruction fully and fairly instructed the jury on the law applicable to the case.
DuBray,
¶ 88
(citing Long,
¶29 Matz offers a very brief argument that his constitutional right to an unanimous verdict was violated by the instructions given to the jury, citing
State v. Weldy,
¶30 The State responds that, while there are alternative ways of defining serious bodily injury under § 45-2-101(66), MCA-namely, risk of death, serious permanent disfigurement, or an expected result of serious permanent disfigurement-these alternate definitions do not represent separate elements or offenses. Thus, the State contends that a specific unanimity instruction was not necessary because the jurors had already been instructed to find a unanimous verdict as to the charge of aggravated assault, which included the alternative means of satisfying the single element of serious bodily injury. We agree.
¶31 “[Ljegislatures frequently enumerate alternative means of committing a crime without intending to define separate elements of separate crimes ....”
Weldy,
¶32 This case requires the same outcome because the alternative definitions set forth in § 45-2-101(66), MCA, merely describe different ways or means of seriously injuring another while committing the offense, and do not define different offenses or different elements of one offense. Matz was charged with only one criminal offense, with one set of elements thereof. Therefore, the District Court did not abuse its *210 discretion in instructing the jury with regard to unanimity, and Matz’s constitutional rights were not implicated thereby.
¶33 (4) Did the District Court abuse its discretion by excluding evidence that the alleged victim had marijuana and a marijuana pipe in his pocket at the time of the altercation ?
¶34 “A district court has broad discretion in determining the relevance and admissibility of evidence.”
State v. Hicks,
¶35 When Andersen was taken to the hospital after the altercation, a blood test was conducted that indicated he had a blood alcohol content of .028. The defense was allowed to cross-examine Andersen about his drinking that evening, but when the defense sought to introduce the marijuana and marijuana pipe found on Andersen that night, the State objected on relevance grounds. The District Court, citing this Court’s holdings in
State v. Gleim,
¶36 Matz initially argues that this evidence was highly relevant to his self-defense theory, because the marijuana may have suggested why Andersen acted in the manner Matz had alleged-that is, attacking Matz and knocking him off his bicycle. The State responds that such a connection between the marijuana and Andersen’s behavior, without more, is entirely speculative, but, additionally, that Matz did not offer the evidence for this purpose at trial. Matz’s relevance argument having not been made at trial, we need not consider it further.
¶37 At trial, Matz argued that the
only thing this evidence does is prove that at the time these incidents happened, these were in his pocket. I have no proof beyond that, intend to offer it as that. But that, those are facts that are there. I think we are entitled to present the scene of the crime, what happened, who had what.
Thus, Matz essentially intended to impeach Andersen’s credibility by *211 reason of Andersen’s possession of the marijuana. Matz argues that this was also a proper purpose pursuant to M. R. Evid. 404(a)(2), which permits introduction of character evidence concerning a victim.
¶38 M. R. Evid. 404(a)(2) provides that evidence “of a pertinent trait of character of the victim of the crime” may by offered by an accused. However, Matz did not offer evidence of any “pertinent trait” about Andersen, only the marijuana he possessed. About such evidence, this Court held in
Gleim,
and reaffirmed in
Sorenson,
“that the mere use of narcotics is not admissible to impeach witness credibility ‘unless it is proposed to show that the witness was under the influence of the drugs at the time the events happened about which she testified.’ ”
Sorenson,
¶39 Affirmed.
