OPINION
{1} Defendant appeals from a judgment and sentence entered after a jury found him guilty of armed robbery and conspiracy to commit armed robbery. The jury had deadlocked on Count I, involving felony murder and the lesser-included offense of second degree murder, and the respective conspiracy counts. The district court thereafter ruled that the failure to poll the jury resulted in an “implied acquittal” of the felony murder and conspiracy to commit felony murder charges. The district court denied Defendant’s motion to bar retrial of the remaining counts and Defendant filed a separate appeal from this order. We consolidated the appeals and now address the following issues: (1) whether the district court properly sentenced Defendant under NMSA 1978, § 31-18-15(A)(2), (4) (1999), both of which provisions require a finding that the crime resulted “in the death of a human being”; (2) whether Subsections 31-18-15(A)(2) and (4) constitute an “enhanced sentence” that may not be further enhanced by other sentencing statutes; (3) whether conspiracy is a crime subject to reduced good time credit; and (4) whether retrial on conspiracy to commit murder is barred because the evidence supports only one conspiracy.
{2} After this ease was assigned to the general calendar, the State moved to sever the appeals and dismiss the appeal from the order addressing retrial. We hereby deny the motion. We affirm as to issues two and four and reverse on issues one and three.
FACTUAL AND PROCEDURAL BACKGROUND
{3} Defendant and Lorenzo Mora were accused of robbing and killing Anthony Baldenegro, an out-of-state truck driver who had stopped at a bar in Lordsburg on the evening of September 24,1999. The State introduced evidence that Defendant and Baldenegro had been drinking for a while before Defendant’s girlfriend, Onisha Aguilera, arrived at the bar with a female friend. The two women, Defendant, and Baldenegro all proceeded toward Aguilera’s apartment. At some point prior to going to Aguilera’s apartment, drugs were obtained. There was also evidence presented that Defendant obtained a syringe and a knife. Defendant and Baldenegro were dropped off near Aguilera’s apartment, and Aguilera joined them later after her friend had gone home.
{4} Defendant and Aguilera were given money by Baldenegro and left the residence to purchase more drags; they were unable to find any and returned to the apartment to find Baldenegro asleep. Defendant and Aguilera left again and ended up at the house of Lorenzo Mora’s mother, where they consumed more drugs until Mora arrived. Defendant and Mora went back to Aguilera’s apartment to get more money from Baldenegro. Although there is a factual dispute with respect to any alleged decision to physically harm Baldenegro, the State presented evidence that Defendant and Mora intended to forcibly take money from Baldenegro, if necessary. The evidence also indicated that Defendant picked up a large metal pipe and gave it to Mora upon their arrival at the apartment. Mora entered the bedroom where Baldenegro was still sleeping, with Defendant entering through the kitchen. Mora then hit Baldenegro with the pipe, fracturing his skull twice and causing his death some hours later. Defendant took Baldenegro’s money and wallet and the two fled to Mexico, along with Aguilera, later that morning. The three were arrested ten days later as they tried to re-enter the country.
{5} Defendant was charged by criminal information with an open count of murder (Count I), conspiracy to commit murder (Count II), armed robbery (Count III), and conspiracy to commit armed robbery (Count IV). At trial the jury was presented conflicting versions with respect to Defendant’s role in the killing. Mora, who had previously pled guilty to second degree murder, testified that he alone was responsible for the robbery and killing, and that Defendant was in the kitchen and rushed in to stop Mora. The State relied in part on prior inconsistent statements made by Mora that implicated Defendant in the robbery and killing. With respect to Count I, the case was submitted to the jury with instructions that it could find Defendant guilty of felony murder, guilty of the lesser-included offense of second degree murder, or not guilty. These alternatives were also submitted for the accompanying conspiracy count, Count II. The jury hung on Counts I and II, but returned guilty verdicts on Count III, armed robbery, and Count IV, conspiracy to commit armed robbery. The district court declared a mistrial on Counts I and II, but did not poll the jury.
{6} The district court sentenced Defendant to the fifteen-year basic sentence authorized by Section 31-18-15(A)(2) for the armed robbery conviction. With respect to the conspiracy to commit armed robbery conviction, the district court likewise applied the basic sentence of six years for a third degree felony that resulted in death. See § 31-18-15(A)(4). The district court found that each of these counts should be enhanced by one-third based on aggravated circumstances. Defendant admitted to two prior felonies, and the district court accordingly added four additional years to each count. The court ran all sentences consecutively, for a total commitment of thirty-six years. The court also found that “this is a serious violent offense” that would affect the amount of earned meritorious deductions, or good time credit, available to Defendant. The court subsequently ruled that Defendant could not be retried on the felony murder and the conspiracy to commit felony murder counts because of the failure to poll the jury on these counts. The court ruled that Defendant could be retried on the lesser-included offenses of second degree murder and conspiracy to commit second degree murder.
DISCUSSION
I. The “Resulting in Death” Finding
{7} Defendant posits two reasons why he should not have been sentenced for crimes resulting in the death of a person under Subsections 31-18-15(A)(2) and (4). First, he asserts the district court was barred by collateral estoppel from making the requisite factual finding because he was impliedly acquitted on the felony murder count (Count I) when the jury hung on Counts I and II and then was discharged without being polled. Second, he argues that under Apprendi v. New Jersey,
{8} In Apprendi, the United States Supreme Court held that “[o]ther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.” Id. at 490,
{9} We have addressed the effect of Apprendi on New Mexico’s sentencing scheme twice. State v. Morales,
{10} Our rationale in Wilson was that “Sections 31-18-15 and 31-18-15.1 should be read together to provide for a range of sentences, and that sentencing within this range ... is constitutional” because there is no danger that the trial judge’s decision can increase the maximum punishment which could be imposed based on the jury’s verdict. Id. ¶¶ 4,16-17. The State essentially asserts that the decision under Section 31-18-15 whether the basic sentence can be increased because a crime “resulted in death” is indistinguishable from the decision whether to aggravate sentence under Section 31-18-15.1
{11} We disagree. First, Wilson addressed the ability of district courts to adjust sentences up or down within a given range based on historically well-established aggravating or mitigating factors. The range for any given sentence is dependent on the basic sentence determined under Section 31-18-15(A). Wilson did not address in any way the impact of Apprendi on the determination of the basic sentence applicable to a given crime following a jury verdict.
{12} Subsections 31-18-15(A) provides a clear and marked (six years) distinction between the basic sentence for a “plain” second degree felony and the basic sentence for a second degree felony resulting in a death. The difference in the basic sentence between a “plain” third degree felony and a third degree felony resulting in death is three years. § 31-18-15A. The fact of death caused by the crime thus acts as a trigger to increase the applicable basic sentence materially beyond that set for the underlying felony. In this sense, “resulting in death” elevates the seriousness of the crime and operates in effect as an element of the crime. As we recognized in Wilson, this consequence requires that the basic sentence-enhancing fact be submitted to and decided by the jury.
{13} The State argues that, even assuming Apprendi applies, the error of not having the jury decide if the crime resulted in death is harmless because the evidence in favor of the judge’s finding is overwhelming. See State v. Padilla,
{14} In this sense, this ease is different from United States v. Friedman,
{15} Here, the jury in fact failed to find . Defendant guilty of felony murder or second degree murder and their accompanying conspiraey counts. To find that Defendant’s acts in connection with the more attenuated armed robbery resulted in the victim’s death is not consistent with the jury’s failure to find him guilty of the death directly. The jury’s failure to convict Defendant of a crime that would have found him responsible for the death argues against the district court’s action and brings into clear relief the constitutional underpinnings of Apprendi.
{16} State v. Shije,
{17} Similarly, the other cases cited by the State following Shije do not address the Apprendi issue we resolve today. For example, State v. Guerro,
II. Alleged Double Enhancement
{18} Defendant maintains that he was subject to an impermissible “double enhancement,” first under the increased sentencing authority under Subsections 31-18-15(A)(2) and (4), and then an additional one-third of the basic sentence based on a finding of aggravating circumstances under Section 31-18-15.1. Defendant refers us to three cases in support of this claim. All three of these cases involve the use of a prior conviction to support an element of a subsequent conviction, and also used to support enhancement under our habitual offender statute. In State v. Keith,
{19} It is evident that these cases do not support Defendant’s argument, because there is no dual use here of a prior conviction or factual predicate. In State v. Peppers,
III. Good Time Credit
{20} We agree with Defendant’s claim that the district court was not authorized to limit his good time credit for the conspiracy to commit armed robbery conviction. We also agree with Defendant that any alleged problems with preservation do not affect our review, because we are considering the legality of the sentence. A district court does not have jurisdiction to impose an illegal sentence because its power to sentence is “derived exclusively from statute.” State v. Martinez,
{21} Turning to the merits, the relevant statutory authority, NMSA 1978, § 33-2-34 (1999), which we will refer to as the Earned Meritorious Deductions Act (EMDA), authorizes up to thirty days of credit per month for nonviolent offenders, but limits credit to four days per month for prisoners who have been convicted of a serious violent offense. The statute defines a serious violent offense in two ways. First, there are thirteen enumerated offenses that satisfy the definition as a matter of law. § 33-2-34(L)(4)(a) — (m). Second, the statute lists thirteen additional offenses that may trigger the EMDA’s good time credit reduction provisions. § 33-2-34(L)(4)(n). Here, Defendant’s armed robbery conviction falls within the mandatory portion of the statute, Section 33-2-34(L)(4)(g), and we therefore only need to address whether conspiracy to commit armed robbery is subject to a credit reduction under the EMDA.
{22} In Morales,
{23} The State’s argument runs afoul of at least two basic rules of statutory construction. First, we do not read additional language into a statute when it makes sense as written. See State v. Gutierrez,
IV. Conspiracy
{24} Finally, Defendant contends that he may not be retried on the conspiracy to commit second degree murder charge because the evidence supported only one agreement. Cf. State v. Post,
{25} Defendant claims that there was no view of the evidence to support an agreement to commit murder and an agreement to rob Baldenegro. We disagree. As pointed out by the State, there was evidence to support the view that Defendant and Mora agreed to rob Baldenegro. In addition to other indications that they would harm Baldenegro if necessary, Defendant picked up the pipe outside of the apartment and gave it to Mora.
CONCLUSION
{26} For the reasons discussed above, we reverse on issues one and three and affirm in all other respects. We remand with instructions to vacate that portion of the judgment and sentence that reduces good time credit for the conspiracy to commit armed robbery conviction, and to resentence Counts III and IV under Subsections 31-18-15A.
{27} IT IS SO ORDERED.
