OPINION
The State appeals the trial court’s dismissal of a firearm enhancement count contained in the criminal information charging Defendant with involuntary manslaughter by negligent use of a firearm. We hold that, because use of a firearm is one of the elements of the crime charged, see Swafford v. State, 112 N.M. 3, 16, 810 P.2d 1223, 1236 (1991), the trial court properly dismissed the firearm enhancement count. We thus affirm.
BACKGROUND
This case arose out of a tragic game of "quick draw” between Defendant and Victim. Defendant was charged with involuntary manslaughter by negligent use of a firearm. See NMSA 1978, §§ 30-2-3(B), 30-7-4(A)(3) (Repl.Pamp.1984). Under the information, the State also sought to enhance any sentence imposed by one year, based on the alleged use of a firearm in the commission of the offense. See NMSA 1978, § 31-18-16(A) (Repl.Pamp.1990). Before trial, Defendant moved to dismiss the enhancement count, arguing that application of the firearm enhancement statute would violate the prohibition against double jeopardy under the federal and state constitutions. See U.S. Const. amend. V; N.M. Const, art. II, § 15. After a hearing, the trial court granted Defendant’s motion and dismissed the firearm enhancement count. The State appealed.
DISCUSSION
This Court has recognized that Swafford articulates a new, two-part test for determining whether a defendant has been subjected to double jeopardy in a single prosecution, and has applied the Swafford test when the firearm enhancement statute was involved. State v. Charlton, 115 N.M. 35, 39-41, 846 P.2d 341, 345-47 (Ct.App.1992), cert. denied, 114 N.M. 577, 844 P.2d 827 (1993); State v. Elmquist, 114 N.M. 551, 555, 844 P.2d 131, 135 (Ct.App.1992). In an effort to correctly apply the holding in Swafford to the facts of this case, we requested the parties to provide supplemental briefing to discuss the relevance of Elmquist to the facts of this appeal. The State concentrated its supplemental brief on the statutory analysis used in Elmquist to determine legislative intent on an issue unrelated to double jeopardy considerations. However, we consider the relevant discussion in Elmquist to be its recognition, and the State’s concession in that case, that application of the firearm enhancement stat*568ute to a conviction for shooting into an occupied building, see NMSA 1978, § 30-3-8 (Cum.Supp.1991), violated double jeopardy principles under Swafford. Elmquist, 114 N.M. at 555, 844 P.2d at 135. The State admits in this appeal as well that Swafford is applicable. We thus proceed to apply the relevant test as enunciated in Swafford.
The double jeopardy clause of the fifth amendment “ ‘protects against a second prosecution for the same offense after acquittal. It protects against a second prosecution for the same offense after conviction. And it protects against multiple punishments for the same offense.’” Swafford, 112 N.M. at 7, 810 P.2d at 1227 (footnotes omitted) (quoting North Carolina v. Pearce, 395 U.S. 711, 717, 89 S.Ct. 2072, 2076, 23 L.Ed.2d 656 (1969)). In this appeal, we are not confronted with multiple prosecutions for the same offense; rather, this is a case involving possible multiple punishments for the same offense. Consequently, the double jeopardy value implicated here is that of preventing the trial court from sentencing a defendant to greater punishment than the legislature intended. Swafford, 112 N.M. at 7, 810 P.2d at 1227 (citing Grady v. Corbin, 495 U.S. 508, 516-17, 110 S.Ct. 2084, 2090-91, 109 L.Ed.2d 548 (1990), overruled on other grounds by United States v. Dixon, 509 U.S. -, 113 S.Ct. 2849, 125 L.Ed.2d 556 (1993)) (citing Missouri v. Hunter, 459 U.S. 359, 366, 103 S.Ct. 673, 678, 74 L.Ed.2d 535 (1983)). “[T]he sole limitation on multiple punishments is legislative intent.” Swafford, 112 N.M. at 13, 810 P.2d at 1233.
Under Swafford’s two-part test for ascertaining the legislature’s intent to punish, we first determine whether a defendant’s conduct was “unitary, i.e., whether the same conduct violate[d] both statutes.” Id. Although our Supreme Court did not state a judicial and all-encompassing definition for “unitary conduct,” it nonetheless provided guidelines. The determination of whether a defendant’s conduct is “unitary” requires consideration of the elements of the crimes charged and the facts presented at trial. Id. Under the facts of this case, the criminal charge against Defendant was based on a single act, the negligent use of a firearm. The identical use of the same firearm formed the basis for the charge under the enhancement statute. Thus, we conclude this act was unitary conduct.
Because the first part of the test is answered affirmatively, we next proceed to the second part of the Swafford analysis, a determination of whether the legislature intended to impose multiple punishments for the unitary conduct. Id. at 14, 810 P.2d at 1234. In turn, the second part of the Swafford test has three components. First, “[i]f the legislature expressly provides for multiple punishments, the double jeopardy inquiry must cease.” Id. (citing Hunter, 459 U.S. at 368-69, 103 S.Ct. at 679-80) (emphasis added). Second, if there is not a clear legislative intent, the court must apply the elements test stated in Blockburger v. United States, 284 U.S. 299, 304, 52 S.Ct. 180, 182, 76 L.Ed. 306 (1932), to determine whether one statute is subsumed within the other. Swafford, 112 N.M. at 14, 810 P.2d at 1234. Under the Blockburger test, when the same act violates two different statutes, the inquiry for determining if there are two offenses or only one is “ “whether each provision requires proof of a fact the other does not.’” Swafford, 112 N.M. at 8, 810 P.2d at 1228 (quoting Blockburger, 284 U.S. at 304, 52 S.Ct. at 182). This inquiry focuses on the elements of the statutes, not on the evidence and proof presented at trial. Swafford, 112 N.M. at 8, 810 P.2d at 1228. If the Blockburger test “establishes that one statute is subsumed within the other, the inquiry is over and the statutes are the same for double jeopardy purposes— punishment cannot be had for both.” Swafford, 112 N.M. at 14, 810 P.2d at 1234.
Finally, under the third component, a conclusion that the elements of one statute are not subsumed within the other under Blockburger establishes only a rebuttable presumption that the statutes punish different offenses; only after applying the Block-burger elements test does the court finally *569consider legislative intent using the traditional guidelines of “language, history, and subject of the statutes.” Swafford, 112 N.M. at 14, 810 P.2d at 1234. In the absence of a clear indication that the legislature intended multiple punishment for the unitary conduct, the court should apply the rule of lenity to presume that the legislature did not intend multiple punishment. Id. at 15, 810 P.2d at 1235. Having previously determined that Defendant’s conduct was unitary under the first part of the Swafford test, we proceed to apply the second part of the Swafford analysis to determine whether applying the firearm enhancement statute to the offense of manslaughter by negligent use of a firearm violates the prohibition against placing a defendant in double jeopardy.
We initially determine whether the legislature clearly expressed an intent to impose multiple punishments. The State contends that the legislature’s mere enactment of the firearm enhancement statute indicates a legislative intent to enhance the penalty for any crime committed with a firearm. This Court has previously rejected similar reasoning. See State v. Haddenham, 110 N.M. 149, 153, 793 P.2d 279, 283 (Ct.App.) (rejecting argument that applying the sentencing provisions of the habitual criminal offender and felon in possession statutes does not offend double jeopardy because legislature intended to allow the same fact, the prior felony, to be used under both statutes), cert. denied, 110 N.M. 72, 792 P.2d 49 (1990). We are also unpersuaded by the State’s argument here because our Supreme Court has held that, unless the legislature clearly intended otherwise, using an element of an offense to increase the penalty for the same offense violates double jeopardy. Swafford, 112 N.M. at 16, 810 P.2d at 1236.
In Swafford, the defendant had been convicted of both incest and criminal sexual penetration as a result of a single incident. Id. at 6, 810 P.2d at 1226. Our Supreme Court first considered whether double jeopardy prohibited the defendant from being convicted and sentenced for both crimes. Id. at 15, 810 P.2d at 1235. The Court applied the Blockburger and legislative intent portions of the analysis it had enunciated to determine that “there is no double jeopardy impediment to convicting and sentencing [the defendant] to consecutive terms for both incest and criminal sexual penetration arising out of the same act.” Id. Thus, having determined that neither crime was subsumed within the other, our Supreme Court then considered the issue of whether, at sentencing, in addition to imposing a sentence for the defendant’s incest conviction, the trial court properly used its broad discretion under NMSA 1978, Section 31-18-15.1 (Repl.Pamp.1990), to enhance the defendant’s sentence for criminal sexual penetration on the basis that the victim was the defendant’s half-sister. Swafford, 112 N.M. at 16, 810 P.2d at 1236. The Court held that this enhancement was error because the relationship between the defendant and the victim had already been considered by the legislature in setting the base sentence for the offense of incest, for which the defendant, was already being punished, and the legislature had not specifically included the victim’s relationship to the defendant as an aggravating factor justifying enhancing the penalty for criminal sexual penetration. Id. Thus, “[t]o permit consideration of that [relationship] element as an aggravating factor justifying an upward departure in sentencing for criminal sexual penetration would be repetitive of the punishment the legislature has established for the crime of incest.” Id. Swafford thus disapproved using a required element of an offense twice in a sentencing proceeding— first, to establish the base sentence and, second, to aggravate or enhance the sentence— in the absence of an express legislative intent to so use that element.
If this principle discussed in Swafford prevents using a required element of one offense to aggravate the sentence for another offense resulting from the same conduct, it must necessarily prevent using a required element of an offense to enhance the sentence for that same offense, unless the legislature expressly indicates its intent to impose multiple punish*570ment. We fail to see a significant distinction between these two scenarios. Additionally, as previously stated, where the legislature’s intent is not clearly stated, we are obligated to apply the rule of lenity. Id. at 15, 810 P.2d at 1235. For these reasons, we decline to hold that the mere enactment of the firearm enhancement statute evinces a clear legislative intent to enhance the penalty for all crimes that involve use of a firearm, even when use of a firearm is a necessary element of the offense. If anything, use of the word “firearm” in Section 30-7-4 indicates that the legislature has already considered firearm use as a factor in setting the base penalty for the offense. See Swafford, 112 N.M. at 16, 810 P.2d at 1236 (“[T]he elements of the offense are ipso facto incorporated by the legislature into the base level sentencing for the offense.”).
Second, because we determine that there is no explicit legislative intent to impose the firearm enhancement to the crime of involuntary manslaughter by negligent use of a firearm, we apply the Blockburger test to determine whether the elements of the firearm enhancement statute are subsumed within the elements of involuntary manslaughter by negligent use of a firearm. To apply the Blockburger test, we must first determine what are the “elements” of the firearm enhancement statute. We have previously recognized that, even though Section 31 — 18— 16(A) “does not have ‘elements’ per se,” Charlton, 115 N.M. at 40, 846 P.2d at 346, it can nonetheless be analyzed as though it did because it does have certain requirements. Id. Charlton correctly spelled out the law enunciated in Swafford under that case’s two-part test, and it applied the law to the facts of that case. Nonetheless, we recognize that we have taken a different approach in analyzing the “elements” of the firearm enhancement statute. See generally Taylor Mattis, Precedential Value of Decisions of the Court of Appeals of the State of New Mexico, 22 N.M.L.Rev. 535 (1992); Taylor Mattis, Stare Decisis within Michigan’s Court of Appeals: Precedential Effect of its Decisions on the Court Itself and on Michigan Trial Courts, 37 Wayne L.Rev. 265 (1991). We note, however, that the holding in Charlton would remain the same under our analysis.
The term “element” of a crime or a defense has been defined as “constituent part.” State v. Duncan, 111 N.M. 354, 355, 805 P.2d 621, 622 (1991); Smith v. State, 89 N.M. 770, 774, 558 P.2d 39,43 (1976). Determining the elements of an offense begins with analyzing the statutory language. See Smith, 89 N.M. at 774, 558 P.2d at 43. The elements of an offense are those facts the prosecution must prove beyond a reasonable doubt to establish that the defendant committed the offense. See State v. Ungarten, 115 N.M. 607, 609, 856 P.2d 569, 571 (Ct.App.1993). Section 31-18-16(A), the firearm enhancement statute, applies “[w]hen a separate finding of fact ... shows that a firearm was used in the commission of a noncapital felony.” As we read the firearm enhancement statute, the essential fact of a defendant’s conduct that must be proved before enhancement is proper is that a firearm was used. Id.; see also State v. Kendall, 90 N.M. 236, 242-43, 561 P.2d 935, 941-42 (Ct.App.) (construing former statute), rev’d in part, 90 N.M. 191, 561 P.2d 464 (1977). The fact that the defendant has been convicted of a non-capital felony is simply the condition or prerequisite of the sentencing enhancement. See NMSA 1978, § 31-18-13(A) (Repl.Pamp.1990) (stating that all persons convicted of a crime shall be sentenced).
The elements of involuntary manslaughter as applied to this case require the killing of a human being “in the commission of an unlawful act not amounting to [a] felony.” Section 30-2-3(B). The particular unlawful act alleged in this case was the negligent use of a firearm. Section 30-7-4(A)(3). Involuntary manslaughter is a fourth degree felony. Section 30-2-3(B). Thus, under the facts of this case, the State was required to prove that Defendant negligently used a firearm to commit a noncapital felony and this conduct resulted in the death of a human being. Use of a firearm is the same conduct required to *571enhance Defendant’s sentence under Section 31-18-16(A). Because the State would not be required to prove any additional facts in order to have Defendant’s sentence enhanced, we conclude that the firearm enhancement statute is subsumed within the offense of involuntary manslaughter by negligent use of a firearm. Cf. Haddenham, 110 N.M. at 154, 793 P.2d at 284 (“[I]t is impermissible to sentence both defendants as habitual offenders when the same facts [same prior convictions] were relied upon to convict defendants of the underlying offense of felon in possession of a firearm.”). As a result, “the inquiry is over and the statutes are the same for double jeopardy purposes — punishment cannot be had for both.” Swafford, 112 N.M. at 14, 810 P.2d at 1234. We thus do not continue with the second part of the Swafford analysis by applying other indicia of legislative intent, the third step of this part of the Swafford test. Id. We hold that the trial court correctly dismissed the firearm enhancement count in the information.
We do, however, address the State’s arguments to the contrary. Pointing to the language of Section 30-7-4(A)(3), which refers to “handling or using a firearm or other deadly weapon ” (emphasis added), the State contends that the crime of negligent use of a deadly weapon does not necessarily require the specific use of a firearm. Thus, the State argues, under the reasoning of State v. Gonzales, 95 N.M. 636, 638-39, 624 P.2d 1033, 1035-36 (Ct.App.), overruled on other grounds by Buzbee v. Donnelly, 96 N.M. 692, 634 P.2d 1244 (1981), and State v. Gabaldon, 92 N.M. 230, 234-35, 585 P.2d 1352, 1356-57 (Ct.App.), cert. denied, 92 N.M. 260, 586 P.2d 1089 (1978), applying the firearm enhancement statute to the facts of this case does not violate double jeopardy principles.
In Gabaldon, this Court held that applying the firearm enhancement to a conviction for robbery with a deadly weapon, where the deadly weapon used was a firearm, did not violate double jeopardy. Id at 235, 585 P.2d at 1357. Our rationale was that robbery with a deadly weapon could be committed without using a firearm, such as by using a knife or brass knuckles. Id at 234, 585 P.2d at 1356. Therefore, we concluded that, “[s]ince proof of the offense does not require proof that a firearm was used, it is not a violation of the double jeopardy clause to enhance the penalty when the offense is committed by using a firearm.” Id at 235, 585 P.2d at 1357. Gozales adopted the reasoning of Gabaldon to hold that double jeopardy did not prohibit applying the firearm enhancement statute to increase the penalty for aggravated battery with a deadly weapon. Gonzales, 95 N.M. at 638-39, 624 P.2d at 1035-36. However, unlike the statutes at issue in those cases, NMSA 1978, Section 30-3-5(C) (Repl.Pamp.1984) (aggravated battery with a deadly weapon), and NMSA 1978, Section 30-16-2 (Repl.Pamp.1984) (robbery with a deadly weapon), the statute defining negligent use of a deadly weapon, Section 30-7-4, specifically refers to use of a firearm in each subsection.
We recognize that the particular subsection Defendant is charged with violating, Section 30-7-4(A)(3), refers to “firearm or other deadly weapon” and on that basis differs from the other subsections of the statute, which expressly limit their application to a firearm. However, this language does not make the statute here “identical” to the statutes at issue in Gonzales and Gabaldon. When a criminal statute is written in the alternative, it creates separate offenses for each alternative that are treated separately for double jeopardy purposes. State v. Rodriguez, 113 N.M. 767, 771, 833 P.2d 244, 248 (Ct.App.), cert. denied 113 N.M. 636, 830 P.2d 553 (1992); see also Swafford 112 N.M. at 8-9, n.4, 810 P.2d at 1228-29 n. 4. Because Section 30-7-4(A)(3) provides alternative means for prosecuting the offense of endangering another by negligent use of a deadly weapon, it in effect creates two criminal offenses, negligent use of a firearm and negligent use of an “other deadly weapon,” which we analyze separately. For these reasons, we reject the State’s argument that Gabaldon and Gonzales are dispositive of the issue raised in this appeal.
CONCLUSION
Because we hold that Section 31-18-16(A), the firearm enhancement statute, is sub*572sumed within the crime of involuntary manslaughter by negligent use of a firearm, see Sections 30-2-3(B) & 30-7-4(A)(3), we conclude that the trial court correctly dismissed the firearm enhancement count from the information. We thus affirm the trial court’s decision and remand for further proceedings in accordance with this opinion.
IT IS SO ORDERED.
