Introduction

This commentary examines the New Mexico Supreme Court’s nonprecedential decision in State v. Almentero, affirming two first-degree felony-murder convictions arising from the kidnapping and killing of teenagers Collin Romero and Ahmed Lateef, and the armed robbery of Lateef. Tried jointly with codefendants Jimmie Atkins and Stephen Goldman, Jr., Almentero appealed on multiple jury-instruction grounds.

Three instruction-related issues were presented:

  • Whether the district court’s affirmative response to a jury question—asking if it could convict of both second-degree murder and felony murder—misstated the law;
  • Whether the court erred by not instructing on second-degree murder as a lesser-included offense of felony murder (purportedly needed to capture causation); and
  • Whether the felony-murder and aiding-and-abetting instructions were so confusing—particularly in their use of and/or alternatives for predicate felonies and multiple decedents—as to constitute fundamental error.

The Supreme Court rejected each contention and affirmed, expressly adopting by reference the analysis it had issued for the codefendant in State v. Goldman. Although nonprecedential, Almentero is a useful window into the Court’s current approach to felony-murder instructions, the use of disjunctive alternatives, and the preservation burdens on defendants seeking lesser-included instructions.

Summary of the Opinion

  • Standard of review: Jury-instruction propriety is reviewed de novo; preserved claims for reversible error; unpreserved claims for fundamental error.
  • Jury question (“both second-degree and felony murder?”): The trial court’s “yes” was an accurate statement of law as framed by the instructions given; no reversible error (following Goldman).
  • No second-degree lesser for felony murder: No error where the defense did not request a second-degree instruction as a lesser-included of felony murder (Boeglin places tactical choice on the defense). In any event, UJI 14-202 (felony murder) already included an explicit causation element; thus the complaint that a second-degree instruction was needed to supply causation failed on the merits.
  • “And/or” alternatives and multi-victim accessory instruction: The use of “and/or” to identify predicate felonies (kidnapping and armed robbery), and a single aiding-and-abetting instruction referencing both victims, did not constitute error or cause juror confusion. Defendant’s reliance on State v. Taylor was misplaced (following Goldman). With no error, fundamental error was also absent.
  • Structural error claim: Not addressed; the argument was undeveloped and unsupported by authority.
  • Disposition: Convictions affirmed.

Analysis

Precedents and Authorities Cited

  • State v. Salazar, 1997-NMSC-044: Propriety of jury instructions is a mixed question of law and fact, reviewed de novo.
  • State v. Benally, 2001-NMSC-033: Preserved errors are reviewed for reversible error; unpreserved for fundamental error.
  • State v. Romero, 2023-NMSC-014: Two-step fundamental error inquiry—first identify error, then assess whether it was fundamental.
  • State v. Boeglin, 1987-NMSC-002: Defendants bear the tactical responsibility to request lesser-included homicide instructions; absent a request, they cannot later complain that the court did not give them.
  • State v. Taylor, 2024-NMSC-011: Addresses juror unanimity concerns and the use of disjunctive alternatives; does not condemn “and/or” per se where each alternative is legally valid and supported by the evidence.
  • State v. Adamo, 2018-NMCA-013: If there is no reversible error, there can be no fundamental error in instructions.
  • State v. Turrietta, 2013-NMSC-036; Elane Photography, LLC v. Willock, 2013-NMSC-040: Structural error requires developed argument; appellate courts will not guess at undeveloped claims.
  • Pattern instructions: UJI 14-202 (felony murder—express causation element); UJI 14-212 (second-degree murder); UJI 14-2821 (aiding and abetting—drafted in the singular).
  • Companion authority: State v. Goldman, S-1-SC-40100 (June 30, 2025) (nonprecedential): Addressed the same instruction issues arising from the same incident; analysis adopted here by reference.

Legal Reasoning and Application

A. The court’s “yes” to the jury’s question about convicting of both felony murder and second-degree murder

Almentero challenged the trial court’s affirmative answer to a juror query asking whether the jury could return both felony-murder and second-degree murder convictions. The Supreme Court, adopting its analysis in the companion Goldman decision, held the response accurately reflected the law as framed by the instructions given in this case. Although the decision does not recite the full text of the jury question or every instruction, the Court signals that, read in context with the charges and instructions provided, the jury could permissibly return the convictions described in its question. Accordingly, there was no misstatement of law and no reversible error.

Key point: Appellate assessment of a jury-question response is tethered to the instructions and charges as a whole. When the court’s response conforms to the law as the jury has been instructed, it is not erroneous—even if, in the abstract, “both” convictions might raise concerns in other configurations (e.g., double punishment for a single killing). The Court’s reliance on Goldman underscores the importance of context and the integrated reading of the entire charge.

B. No second-degree lesser-included instruction was required to capture causation for felony murder

Almentero argued that the absence of UJI 14-212 (second-degree murder) as a lesser-included offense of felony murder deprived the jury of a necessary causation element. The Court rejected this for two independent reasons:

  • No request, no error (Boeglin): It is the defendant’s tactical responsibility to request lesser-included homicide instructions supported by the evidence; failure to request forecloses a later complaint that the court did not give them. The Court reaffirmed this longstanding allocation of responsibility.
  • Causation already embedded in UJI 14-202: The felony-murder instruction expressly required the jury to find that “the defendant caused the death … during the commission” of the predicate felony. Because causation was already an element in the felony-murder instruction, a second-degree instruction was unnecessary to supply it. On this ground, there was no instructional error at all, which necessarily precludes a finding of fundamental error (Adamo).

Practical takeaway: Where UJI 14-202 is properly given, its causation requirement stands on its own; courts need not append second-degree instructions simply to reinforce causation. Defendants who want second-degree considered as a lesser alternative must affirmatively request it and show evidentiary support.

C. “And/or” alternatives for predicate felonies did not create reversible or fundamental error

Almentero challenged the use of “and/or” in the felony-murder and aiding-and-abetting instructions to identify the predicate felonies (kidnapping and armed robbery), invoking State v. Taylor to argue that the verdict could rest on an unknown or impermissible ground. The Supreme Court, adopting Goldman’s analysis, rejected the challenge. Taylor does not categorically prohibit disjunctive phrasing; rather, it guards against nonunanimous or legally invalid grounds where the alternatives differ in legal validity or evidentiary support.

Here, the Court accepted that the alternatives presented—kidnapping and armed robbery—were both legally valid felony-murder predicates and supported by the evidence. In that posture, the “and/or” phrasing did not misdirect the jury, undercut unanimity, or render the verdicts unreliable. Thus, there was no error—let alone fundamental error.

Practice note: If a party believes an alternative lack evidentiary support or legal validity, they should seek to strike it, request a unanimity instruction tailored to the alternatives, or request special interrogatories. Absent such preservation—and where both alternatives are valid and supported—“and/or” will not, by itself, undo a conviction.

D. A single aiding-and-abetting instruction referring to both victims was not erroneous

The defendant also argued that the accessory-liability instruction was confusing because it was drafted in the singular (UJI 14-2821) but given in a form that referred to both decedents (Romero and Lateef) in the same instruction (“Romero and/or Lateef”). The Court again adopted Goldman’s analysis to conclude there was no error: read together with the felony-murder instructions and verdict forms, the single instruction did not risk convicting the defendant for one victim’s killing based on aiding and abetting the other’s. There was no demonstrable juror confusion or misdirection.

Best practice: While the Court found no error here, trial courts can avoid similar challenges by issuing separate aiding-and-abetting instructions for each victim or count, mapping each to the relevant predicate felony and decedent to ensure maximal clarity.

E. Structural error argument deemed undeveloped

To the extent the defendant gestured at “structural error,” the Court declined to reach it, citing State v. Turrietta and Elane Photography for the principle that courts do not evaluate undeveloped contentions or guess at their contours. This highlights the importance of developing structure-based arguments with specific authority and analysis.

Impact and Implications

Although nonprecedential, Almentero—paired with Goldman—signals the Court’s current approach to several recurring issues in homicide trials involving multiple victims and felony predicates:

  • Reliance on pattern instructions: UJI 14-202’s causation element is sufficient; courts need not append second-degree merely to reinforce causation. This can streamline charges in felony-murder cases.
  • Preservation matters: Defendants must timely request lesser-included instructions and record supporting evidence. Boeglin remains robust; tactical silence at trial forecloses appellate relief on omitted lessers.
  • “And/or” is not per se invalid: When each alternative predicate is legally valid and supported by evidence, disjunctive phrasing does not automatically produce Taylor problems. Unanimity or special-verdict tailoring becomes essential only where legal validity or evidentiary sufficiency differs materially across alternatives.
  • Multi-victim accessory instructions can pass muster: A single aiding-and-abetting charge referencing multiple victims is not inherently confusing if the jury instructions and verdict forms, read as a whole, cabin the jury’s task and link findings to each victim.
  • Jury questions must be answered within the instructional framework: Trial judges should answer juror questions by reference to the instructions as given. Appellate courts will review those answers in context, not in isolation.

Looking ahead, litigants should expect the Court to: (a) demand preservation on lesser-included requests; (b) tolerate “and/or” where alternatives are valid and proven; and (c) analyze alleged instruction confusion holistically across the entire charge and verdict structure. Counsel aiming to challenge such instructions should build a record with pinpoint objections, alternative drafts, and proposed unanimity instructions or special verdicts.

Complex Concepts Simplified

  • Felony murder (NMSA 1978, § 30-2-1(A)(2)): A killing that occurs during the commission of certain felonies (e.g., kidnapping, armed robbery). The State must prove the defendant caused the death during the felony. New Mexico’s pattern instruction, UJI 14-202, makes causation explicit.
  • Lesser-included offense: A lesser crime whose elements are wholly contained in a greater charged offense. Defendants can ask juries to be instructed on lessers if supported by evidence. In New Mexico, defendants must request such instructions; failure to do so generally waives complaint on appeal (Boeglin).
  • Fundamental error: An error so serious it undermines the reliability or fairness of the trial. Courts first decide whether there was any error; without error, there can be no fundamental error.
  • Accessory (aiding-and-abetting) liability: A person can be convicted as a principal if they intentionally help, encourage, or facilitate another person’s commission of a crime. UJI 14-2821 sets out the elements.
  • “And/or” alternatives in instructions: Disjunctive phrasing can raise concerns about juror unanimity if one alternative is unsupported or invalid. Where both alternatives are valid and supported by evidence, “and/or” is generally permissible.
  • Structural error: Fundamental constitutional defects affecting the trial framework (e.g., total denial of counsel) that are not subject to harmless-error analysis. Such claims must be specifically developed; bare assertions are insufficient.

Conclusion

State v. Almentero affirms two felony-murder convictions and rejects three instruction-based challenges. The Court (1) held the trial judge’s affirmative answer to a juror question about convicting of both felony murder and second-degree murder was accurate given the instructions; (2) found no error in omitting a second-degree lesser for felony murder, both because the defense did not request it and because UJI 14-202 already contains an explicit causation element; and (3) approved, in context, the use of “and/or” to reference multiple predicate felonies and a single aiding-and-abetting instruction covering two victims, finding no error or confusion and therefore no fundamental error.

While nonprecedential, the decision—together with its companion, Goldman—offers clear guidance on New Mexico’s current treatment of felony-murder instructions: stick to the pattern where applicable, preserve requests for lessers, and read the charge as an integrated whole. For trial courts, careful drafting and alignment of instructions and verdict forms remain the best prophylactic against claims of juror confusion; for counsel, timely, targeted objections and alternatives are essential to preserve appellate relief.

Bottom line: The Supreme Court signaled continuity rather than a shift—reaffirming preservation rules for lesser-included offenses, accepting disjunctive alternatives when both are valid and supported, and declining to find fundamental error in multi-victim accessory instructions where the overall charge is coherent and complete.
