OPINION
{1} Defendants David Sanchez, Robert Young, and Reis Lopez are charged by grand jury indictment with the first degree murder of Ralph Garcia, in addition to other charges. The killing took place on August 31, 1999, at the Guadalupe County Correctional Facility (GCCF), where Garcia was a correctional employee and Defendants were inmates. The State seeks the death penalty based on two aggravating factors, murder of a peace officer and murder by an inmate of one who is lawfully on the premises of a penal institution. See NMSA 1978, § 31-20A-5(A), (D) (1981). Defendants moved to dismiss both aggravating circumstances on several grounds. See State v. Ogden,
I. Standard of Review
{2} In Ogden, we established guidelines for the district court to follow in ruling on a motion to dismiss an aggravating circumstance. Aggravating circumstances are not elements of the crime of first degree murder, see NMSA 1978, § 30-2-l(A) (1994), and thus they “are not required to be formally charged in an indictment or ruled on by the grand jury for the existence of probable cause.” Ogden,
{3} We also explained in Ogden that “[p]retrial rulings on the support of aggravating circumstances can present questions of fact, law, or mixed fact and law, and this will affect the standard of review.” Id. at 239,
II. The Aggravating Circumstance of Murder by an Inmate at a Penal Institution
{4} In enumerating the aggravating circumstances that make a first degree murder eligible for the death penalty under the Capital Felony Sentencing Act, the Legislature has specified that it is an aggravating circumstance if, “while incarcerated in a penal institution in New Mexico, the defendant, with the intent to kill, murdered a person who was at the time incarcerated in or lawfully on the premises of a penal institution in New Mexico.” Section 31-20A-5(D). The State alleged in its notice of intent to seek the death penalty that Defendants murdered Garcia with the intent to kill while he was lawfully on the premises of GCCF, a penal institution in New Mexico. Defendants claim that this aggravating circumstance should not apply in this case because GCCF is not a “penal institution” within the meaning of Section 31-20A-5(D) or because Garcia was not lawfully on the premises. We reject both of these arguments.
{5} ’’The chief aim of statutory construction is to give effect to the intent of the legislature.” Roth v. Thompson,
{6} In accordance with this statutory authority, Wackenhut Corrections Corp. had a contract with the County to operate GCCF as a correctional facility. Pursuant to a separate contract between the County and the Department of Corrections, which was incorporated into the County’s contract with Wackenhut, GCCF housed inmates, including Defendants, who were committed to the supervision of the Department of Corrections. These inmates were subject to the typical consequences of incarceration in a public facility, such as receiving time served on their sentences and being subject to prosecution for escape or other crimes directed at inmates, see NMSA 1978, § 30-22-8 (1963) (“Escape from jail consists of any person who shall have been lawfully committed to any jail, escaping or attempting to escape from such jail.”) (emphasis added), and the administrators of GCCF were obligated to comply with specific statutory duties, including the maintenance of a clean facility and the provision of food for the prisoners, NMSA 1978, §§ 33-3-5 (1984) (applying to “independent eontractor[s]”), -6 (1984) (same). We believe it is clear that GCCF is a penal institution within the plain language of Section 31-20A-5. The fact that GCCF housed inmates from the Department rather than county inmates is immaterial both for the definition of “local jail” in Section 33-3-28 and the definition of “penal institution” in Section 31-20A-5(D). Thus, GCCF is a penal institution within the plain language of the statute.
{7} Defendants also claim that Garcia was not lawfully on the premises at the time of the killing because he had not completed his training as a corrections officer. The County’s contracts with Wackenhut and the Department of Corrections provided that GCCF corrections officers receive training that complied with Department and County policies. The contracts further provided that the Department would train all corrections officers at its main training academy or at GCCF, which would be designated as a branch of the Department’s training academy for this limited purpose. After being hired by Wackenhut in January 1999, Garcia attended a ten-week training program at the Department’s main training academy. However, Garcia did not receive his certification from the Department because he did not pass an AR-15 rifle test. The Department issued a waiver of certification for Garcia’s duties inside the facility pending Garcia’s retaking of the rifle test and instructed Wackenhut not to allow Garcia to assume the duties of an armed post, meaning work patrol and transport. Although Garcia was scheduled to attend another rifle training session, he could not attend because of car problems, and the waiver from the Department expired on May 31, 1999. Garcia was later trained in the use of a shotgun and pistol, but he did not attend another training session for the AR-15 rifle prior to his death and thus had not been certified as a corrections officer by the Department. Following Garcia’s death, the Department notified Wackenhut that it was not to allow uncertified individuals to work on posts designated for correctional officers. From the time it began operating GCCF through the time of the alleged murder, Wackenhut had used only shotguns and pistols at the correctional facility and did not use the AR-15 rifle. The Department’s training academy branch at GCCF did not require AR-15 rifle training, and the Wackenhut corrections officers who attended training at this branch, rather than the main training academy Garcia attended, received certification from the Department despite the absence of AR-15 rifle training.
{8} In arguing that Garcia’s presence on the premises of GCCF was unlawful due to his lack of certification, we believe that Defendants overlook the plain language and purpose of the statute. Section 31-20A-5(D) applies to anyone lawfully on the premises of a penal institution, not just certified corrections officers. Thus, this provision includes other employees at the institution who are not certified corrections officers, as well as visitors and other inmates. The completeness of Garcia’s training had no effect on Garcia’s lawful presence at GCCF. Garcia was an employee of GCCF and was authorized by GCCF administrators to be on the premises at the time of the killing. In their motions to dismiss, Defendants challenged that Garcia was a peace officer within the meaning of Section 31-20A-5(A), which is discussed further below. However, Defendants did not challenge the State’s allegation that Garcia was murdered while acting in the course of his duties as a GCCF employee, and Defendant Sanchez noted in his motion to dismiss that “it is undisputed that [Garcia] was employed by the Wackenhut Corporation and working as a correctional officer at the time of his death.” Garcia was therefore lawfully present at the facility within the plain meaning of Section 31-20A-5(D).
{9} Further, the legislative purpose of this aggravating circumstance is to deter inmates from committing murder. See Roberts v. Southwest Cmty. Health Servs.,
III. The Aggravating Circumstance of Murder of a Peace Officer
{10} As a separate aggravating circumstance, the Legislature included cases in which “the victim was a peace officer who was acting in the lawful discharge of an official duty when he [or she] was murdered.” Section 31-20A-5(A). In its notice of intent to seek the death penalty, the State alleged that Garcia was a peace officer acting in the lawful discharge of an official duty when he was murdered. Defendants argue that this aggravating circumstance is inapplicable in this case for three reasons: (1) corrections officers and jailers are not peace officers within the meaning of Section 31-20A-5(A); (2) the employees of GCCF were neither corrections officers nor jailers; or (3) Garcia was not a corrections officer or jailer, and therefore not a peace officer, at the time of his alleged murder. For the reasons that follow, we conclude that there is probable cause to support this aggravating circumstance.
A. Whether Corrections Officers and Jailers are Peace Officers
{11} Defendants first claim that the Legislature did not intend to include corrections officers and jailers in its reference to “peace officers” in Section 31-20A-5(A). Defendants contend that corrections officers, whose principal duty is to hold individuals in custody rather than to maintain public order, perform a different role than peace officers. Defendants argue that corrections officers only occasionally act in the role of peace officers, when making an arrest or enforcing laws on the premises of a New Mexico correctional facility. Defendants also argue that Section 31-20A-5 protects corrections officers in other ways, by establishing an inmate’s murder of employees of the Department of Corrections as one aggravating circumstance, Section 31-20A-5(E), and an inmate’s murder of anyone lawfully on the premises of a penal institution as another aggravating circumstance, Section 31-20A-5(D). Defendants contend based on these provisions that the Legislature would have expressly included corrections officers in Section 31-20A-5(A) if it had intended to provide them with additional protection as peace officers. We review de novo the district court’s determination that corrections officers and jailers are peace officers for purposes of Section 31-20A-5(A). See Ogden,
{12} In Ogden, this Court noted that there is no directly applicable definition for “peace officer” in Section 31-20A-5(A).
{13} The State in Ogden sought the death penalty for the murder of a community service officer (CSO). Id. at 237,
{14} Based on these facts, the district court in that case had found that CSOs are not peace officers within the meaning of Section 31-20A-5(A) because they are not expressly recognized as peace officers by statute. Id. at 243,
{15} Applying these principles, we concluded in Ogden that CSOs are peace officers within the meaning of Section 31-20A-5(A). Id. at 244-45,
{16} Based on our analysis in Ogden, the question we must address in this case is whether corrections officers and jailers maintain public order or peace in such a way that the Legislature intended to provide them with extra protection to encourage their service and deter violent acts against them. We answer this question by turning to other statutes dealing with peace officers, including those specifically applying to jailers and corrections officers.
{17} The Legislature has defined “peace officer” for purposes of the Criminal Code as “any public official or public officer vested by law with a duty to maintain public order or to make arrests for crime, whether that duty extends to all crimes or is limited to specific crimes.” NMSA 1978, § 30-1-12(0 (1963). This Court has held that jailers are included in this statute because “[a] jailer is an officer in the public domain, charged with the duty to maintain public order.” State v. Rhea,
[j]ailers and any employee of a local jail who has, at the particular time, the principal duty to hold in custody any person accused or convicted of a criminal offense or placed in the legal custody or supervision of a local jail shall have the power of a peace officer with respect to arrests and enforcement of laws when on the premises of a local jail, while transporting a person committed to or under the supervision of a local jail, while supervising any person committed to or under the supervision of a local jail anywhere within the state or when engaged in any effort to pursue or apprehend such a person.
Section 33-3-28(A). The Legislature further provided that “[cjrimes against a jailer, including those persons employed by an independent contractor, shall be deemed the same crimes and shall bear the same penalties as crimes against a peace officer.” Section 33-3-28(C).
{18} Following our decision in Rhea, the Court of Appeals held that corrections officers were not “peace officers” within the meaning of Section 30-1-12(0) because, unlike jailers, the statute specifically governing corrections officers, NMSA 1978, § 33-1-10 (1984, prior to 1986 & 1987 amendments), did not at that time state that crimes against corrections officers are to be treated as crimes against peace officers, even though Section 33-1-10 did give corrections officers the power of a peace officer with respect to arrests and enforcement of laws when on the premises of a New Mexico correctional facility or while transporting a person committed to or under the supervision of the corrections department. State v. Tabaha,
{19} The definition of “peace officer” in Section 30-l-12(C) is not directly applicable to Section 31-20A-5(A) because that definition applies only to the Criminal Code, Ogden,
{20} Defendants speculate that this Court believed in Ogden that corrections officers are not peace officers because we cited a case from another jurisdiction, People v. Perry,
{21} In Ogden, this Court emphasized the “peace-keeping nature” of the duties of CSOs and the dangerousness of their peacekeeping role.
{22} We reject Defendants’ argument that Section 31-20A-5(A) would be duplicative of Section 31-20A-5(E) by holding that “peace officer” includes corrections officers. While it is true that Section 31-20A-5(E) protects employees of the Department of Corrections, it does not protect jailers, including employees of independent contractors such as GCCF, whom the Legislature expressly designated as peace officers under certain circumstances. In addition, this provision applies not only to corrections officers employed by the Department but to all Department employees. Similarly, Section 31-20A-5(D) is not duplicative of Section 31-20A-5(A) because Section 31-20A-5(D) also applies to individuals other than corrections officers, including visitors and other inmates. As shown by the scope of these provisions, Section 31-20A-5(E) and Section 31-20A-5(D) are designed to deter murders committed by inmates. Unlike Section 31-20A-5(A), these provisions would not provide the same level of protection against murders committed by someone other than an inmate against a corrections officer who is carrying out an official duty, for example, a murder of a corrections officer by an individual attempting to help an inmate escape. By contrast to Section 31-20A-5(D) and Section 31-20A-5(E), “[t]he killing-of-a-peace-officer aggravating circumstance is designed to make criminals think twice before firing at a dark uniform.” Ogden,
{23} We also reject Defendants’ reliance on the rule of lenity. As we noted in Ogden, this rule applies only if traditional rules of statutory construction prove futile in ascertaining a statute’s meaning.
B. Whether GCCF Employees are Jailers or Corrections Officers
{24} Defendants argue that GCCF employees are not “jailers” within the meaning of Section 33-3-28 because the statute defines “jailer” as “any employee of a local jail who has inmate custodial responsibilities, including those persons employed by private independent contractors who have been designated as jailers by the sheriff,” Section 33-3-28(D)(l). Defendants also contend that the requirement of designation by the sheriff is supported by NMSA 1978, . § 29-1-9 (1979), which requires appointment in writing by state authorities in order to exercise the powers of a peace officer. Defendants argue that, because the employees of GCCF were not designated by the Guadalupe County Sheriff, as required of jailers in Section 33-3-28(D)(l), they do not have the peace officer powers stated in Section 33-3-28(A). We disagree.
{25} The Legislature expressly declared that “any employee of a local jail who has, at the particular time, the principal duty to hold in custody any person accused or convicted of a criminal offense or placed in the legal custody or supervision of a local jail shall have the power of a peace officer” under the same circumstances empowering jailers as peace officers. Section 33-3-28(A). Therefore, the Legislature did not make designation as a jailer by the sheriff a necessary condition for peace officer status under this statute. For this reason, Defendants’ reliance on Section 29-1-9 as a basis for requiring designation by the sheriff is misplaced. Section 33-3-28(D)(2) defines a “local jail” as “a facility operated by a county, municipality or combination of such local governments or by a private independent contractor pursuant to an agreement with a county, municipality or combination of such local governments and used for the confinement of persons charged with or convicted of violation of a law or ordinance.” (Emphasis added.) GCCF is an independent contractor pursuant to a contract with the board of commissioners of Guadalupe County. It houses inmates who have been convicted of crimes based on a contract between Guadalupe County and the Department of Corrections. Therefore, GCCF is a local jail under Section 33-3-28(D), and its guards are “employees of a local jail” who have the powers of a peace officer under the circumstances specified in Section 33-3-28(A).
{26} In addition, although the definition of “jailer” includes designation by the sheriff, the Legislature has also provided that “[t]he common jails shall be under the control of the respective sheriffs, independent contractors or jail administrators hired by the board of county commissioners or other local public body or combination thereof.” Section 33-3-1(A). In Ogden, this Court held that formal, specific legislative action was not necessary to confer peace officer status on CSOs:
the fact that CSOs hold their public employment is what vests them by law with the duty to maintain public order. There is no need for specific legislation stating that the CSOs are vested by law to maintain public order. Such a judicial construction employs an artificial and unduly narrow definition of the term “vested by law,” and it incorrectly deprives the legislature of the ability to enact broad, general statutes.
{27} In Ogden, we determined that, “[r]ather than over-literalize the Vested by law’ language in the statutory definitions, our emphasis should focus on the maintenance of public order or peace requirement, the more substantive and limiting language of the definitions.”
C. Whether Garcia was a Jailer or Corrections Officer at the time of the Alleged Murder
{28} Defendants argue that there is no evidence that Garcia was making an arrest or enforcing the laws at the time of his alleged murder and that the statutory designation of jailers and corrections officers thus does not apply. This factual argument was not raised in Defendants’ motions to dismiss and was not a subject of the limited Ogden evidentiary hearing. As a result, this issue is not properly before this Court on interlocutory appeal. See Rule 12-216(A) NMRA 2004. In any event, we determine that the State established probable cause to believe that Garcia was murdered while in the lawful discharge of duties conferring peace officer status. Section 33-3-28(A). Based on this Court’s holding in Rhea that jailers maintain the public order, we believe that the Legislature intended its reference to “enforcement of laws” in Section 33-3-28(A) and Section 33-l-10(A) to apply to the duty of corrections officers to maintain order in the correctional facility, 3 which was one of Garcia’s primary duties at GCCF. Defendant Sanchez noted in his motion to dismiss that it was undisputed that Garcia was engaging in his duties as a corrections officer at the time of the killing. This fact is supported by references at the evidentiary hearing to a riot, as well as by the supplemental authority submitted to this Court by Defendants on appeal, which indicates that the United States Department of Justice denied federal death benefits to Garcia’s widow and also recites that Garcia’s death occurred while he was responding to a physical altercation between inmates. There is probable cause to believe that Garcia, while trying to maintain order, was enforcing the law at the time of his alleged murder and thus acting in his capacity as a peace officer.
{29} Finally, Defendants contend that Garcia was not a corrections officer because he had not completed training from the Department of Corrections. Defendants rely on the statutory requirement that “[m]embers of the corrections department correctional officer force, excluding correctional specialists, ... successfully pass any physical and aptitude examination the department may require.” NMSA 1978, § 33-l-ll(E) (1986). As described above, Defendants introduced evidence that Garcia failed to successfully pass a rifle test and that the Department of Corrections notified GCCF, after Garcia’s death, that those who had not been certified by the Department were not to serve as corrections officers.
{30} We do not believe that Garcia’s failure to retake the rifle test nullifies his status as a peace officer under Section 33-3-28 as a matter of law. Section 33-1-11(E) does not apply to jailers and employees of local jails designated as peace officers. Section 33 — 3— 28(B) specifically provides that “[j]ailers who are employees of an independent contractor shall not be required to attend the basic training program for law enforcement officers at the New Mexico law enforcement academy.” In addition, the statute that allows the Department of Corrections to contract for correctional or jail services provides that “[w]hen the contractor begins operation of a facility for which private contractor operation is authorized, his [or her] employees performing the functions of correctional officers shall be deemed correctional officers for the purposes of Section[] 33-1-10,” which empowers corrections officers to act as peace officers. NMSA 1978, § 33-l-17(E) (1995). Although this independent contractor provision does not apply in this case because GCCF had a contract with the County instead of with the Department of Corrections, it is noteworthy that this statute does not require individual officer compliance with training requirements in order for the independent contractor employee to be considered a peace officer. The Legislature deemed the key factors for peace officer status to be the performance of the functions of correctional officers and the existence of a contract between the employer and the public body responsible for the operation of a corrections facility. These factors were met in the present case.
{31} A defect in a guard’s training might affect the independent contractor’s compliance with the government contract. See NMSA 1978, § 33-3-27(C) (providing that an agreement with a private independent contractor for the operation of jails “shall provide for the independent contractor to provide and pay for training for jailers to meet minimum training standards which shall be specified in the contract”), (F)(2) (2001) (providing for termination of the contract for cause if the independent contractor fails to meet a contract provision that “seriously affects the operation of the jail”). The County’s contract with Wackenhut in this case, for example, required that its corrections officers be trained by the Department. Nonetheless, we believe that the Legislature did not intend to deprive employees of independent contractors of the authority necessary to carry out the important and dangerous functions of a corrections officer based on an independent contractor’s failure to fully comply with contractual obligations. As in Ogden, we believe our focus should be on the maintenance of public order requirement.
{32} Moreover, unlike the question whether corrections officers or independent contractor jailers are, generally, peace officers within the meaning of Section 31-20A-5(A), which is clearly a question of law, we believe that the question whether, under the circumstances in this case, Garcia had the powers of a peace officer raises a mixed question of fact and law. “When the applicability of an aggravating circumstance raises a question of fact or a mixed question of fact and law, the district court should grant the defendant’s motion to dismiss the aggravating circumstance only when it finds that there is not probable cause to support the aggravating circumstance.” Ogden,
IV. Conclusion
{33} We conclude that the State established probable cause to believe that GCCF is a penal institution in New Mexico and that Garcia was lawfully on the premises of GCCF when he was allegedly murdered. As a result, we affirm the district court’s denial of Defendants’ motion to dismiss with respect to the aggravated circumstance listed in Section 31-20A-5(D). We further hold that jailers and corrections officers are peace officers within the meaning of Section 31-20A-5(A) and that the State established probable cause to believe that the guards at GCCF, and Garcia in particular, had peace officer powers at the time of the killing. We therefore also affirm the district court’s denial of Defendants’ motion to dismiss with respect to the aggravated circumstance of murder of a peace officer. We remand to the district court for further proceedings.
{34} IT IS SO ORDERED.
Notes
. We note that, by using the word "includes,” the Legislature did not intend to create an exhaustive list of penal institutions.
. Defendants rely on a case from the Court of Appeals, Callaway v. N.M. Dep't of Corr.,
. Contrary to Defendant Sanchez’s contention, nothing in Gutierrez contradicts this interpretation of the Legislature's intent or otherwise exempts custodial duties from the peace officer powers of corrections officers. See Gutierrez,
