Reaffirming Strict Limits on Self-Defense and Castle Doctrine in Domestic Homicides: Commentary on State v. Ricoy

Reaffirming Strict Limits on Self-Defense and Castle Doctrine in Domestic Homicides: Commentary on State v. Ricoy

Case: State v. Ezequiel Profeta Ricoy, No. S-1-SC-40471, Supreme Court of New Mexico (Nov. 10, 2025) – Nonprecedential Decision under Rule 12‑405 NMRA.

I. Introduction

The Supreme Court of New Mexico’s nonprecedential decision in State v. Ricoy arises from a domestic and property-related confrontation that ended in the fatal shooting of a stepson by his stepfather outside the family home. Although the Court explicitly resolved the appeal by unpublished “decision” because the issues had already been addressed in prior New Mexico cases (Rule 12‑405(B)(1) NMRA), the opinion is an instructive synthesis and reaffirmation of four critical areas of New Mexico criminal law:

  • What evidence suffices to prove deliberate intent for first‑degree willful and deliberate murder;
  • When a defendant is entitled to jury instructions on:
    • self-defense,
    • voluntary manslaughter as a lesser-included offense, and
    • defense of habitation (New Mexico’s version of the “castle doctrine”);
  • How courts apply the reversible error vs. fundamental error standards to omitted jury instructions; and
  • When failure to request a particular instruction can constitute ineffective assistance of counsel under Strickland v. Washington.

The defendant, Ezequiel Profeta Ricoy, challenged his conviction for first-degree willful and deliberate murder of his stepson, Brendan Kern, along with related charges arising from his firing an AR‑15 rifle toward the victim’s fiancée, their young children, and a friend. He raised three principal appellate issues:

  1. Insufficiency of evidence of deliberate intent for first-degree murder;
  2. Error in failing to instruct on:
    • self-defense,
    • voluntary manslaughter, and
    • defense of habitation; and
  3. Ineffective assistance of counsel for not requesting a defense-of-habitation instruction.

The Supreme Court rejected all claims and affirmed the convictions. Although nonprecedential, Ricoy provides a clear, tightly reasoned application of existing New Mexico law that will be highly instructive to trial courts and practitioners confronting domestic homicides, particularly where the defendant attempts to invoke self-defense or a home-defense (“castle”) theory in a setting involving family members or invited guests.

II. Factual and Procedural Background

A. Factual Background

The Court’s description of events, taken in the light most favorable to the verdict, paints the following sequence:

  • Family relationships and living situation. Defendant had recently married the victim’s mother, Kelly Kern, and lived with her in the victim’s childhood home. Kelly suffered from multiple sclerosis, used a wheelchair, and was unable to walk.
  • Work arrangement and prior conflict. About a week before the killing, Defendant hired the victim (Kern) to help renovate a trailer. After an argument over whether the victim could bring his own vehicle and a television to the worksite, Defendant fired him. The victim left a cooler in Defendant’s truck, expecting continued work. Defendant later disparaged the victim and his siblings as “useless” and criticized how they treated Kelly—evidence of animus.
  • Plan to retrieve the cooler. On the day of the shooting, Kelly told the victim’s fiancée, Emili, that the cooler would be placed outside and that Emili and the victim could come by to pick it up. Only when the victim was nearly there did Defendant object to the arrangement and to the victim’s presence on the property.
  • Arrival at the house. Emili arrived with:
    • the victim,
    • their two minor children, and
    • a friend, Jaime.
    Emili approached the house looking for the cooler, speaking with Kelly by phone. The victim remained in the vehicle with Jaime and the children.
  • Escalation inside the house. Defendant went outside briefly, then returned inside still protesting the victim’s visit. Emili, still on the phone, overheard Defendant emphatically say he did not want the victim or “any Kerns” on the property. Defendant then yelled into the phone at Emili and told her she would “regret ever coming.” Recognizing his anger, Emili began walking back toward the vehicle intending to leave and ended the call.
  • Retrieval of the AR‑15 and initial shots. Inside, Defendant retrieved an AR‑15 assault rifle. Kelly tried to grab his arm to stop him, but he “shrugged [her] off.” Defendant went out to the porch and opened fire as Emili was still moving toward the vehicle. These were described as “warning shots” in the record, but they were fired in the direction of Emili and the vehicle.
  • The victim exits the vehicle. Only after several shots were fired did the victim exit the vehicle. He crossed paths with Emili as she ran back, pushing her behind him—protective conduct—while Emili continued running to the vehicle. The victim then stood with his hands raised and said, “We’re leaving.”
  • Fatal shots. Defendant continued firing. From a distance of approximately 10 to 30 feet, Defendant shot the victim twice in the chest and neck, fatally wounding him. In total, Defendant fired nine shots, with several also striking the front of the vehicle that contained the children and Jaime.
  • Post-shooting statements.
    • On a 911 call, when Emili asked what caliber bullets Defendant had used, Defendant responded “that’s none of your f***ing business” and laughed.
    • To police, he described the victim and family as “arrogant pricks” for coming to the property despite his objections.
  • Defendant’s account to police. Defendant claimed:
    • the victim had “two things” in his hands (later shown to be an energy drink can and a cell phone),
    • the victim “charged at him,” and
    • he feared being beaten up by the younger, larger victim.
    He did not identify the objects as weapons capable of causing death or great bodily harm.

B. Charges, Trial, and Verdict

Defendant was charged with:

  • first-degree willful and deliberate murder (NMSA 1978, § 30‑2‑1(A)(1)),
  • two counts of abuse of a child not resulting in death or great bodily harm,
  • aggravated assault, and
  • shooting at or from a motor vehicle.

At trial, Defendant requested jury instructions on:

  • the lesser-included offense of second-degree murder,
  • the lesser-included offense of voluntary manslaughter, and
  • self-defense.

The district court:

  • Granted the request for a second-degree murder instruction;
  • Denied the requests for:
    • a voluntary manslaughter instruction; and
    • a self-defense instruction,
    finding insufficient evidence to support either theory.

The jury convicted Defendant of:

  • first-degree willful and deliberate murder,
  • two counts of child abuse (no death or great bodily harm),
  • aggravated assault, and
  • shooting at or from a motor vehicle.

Defendant was sentenced to life imprisonment plus nine years and appealed directly to the New Mexico Supreme Court.

III. Summary of the Supreme Court’s Decision

The Supreme Court (Justice Zamora writing, with all justices concurring) affirmed the convictions and held:

  1. Sufficiency of the evidence. There was substantial evidence of deliberate intent to support the first-degree murder conviction. The Court relied on:
    • Defendant’s animus toward the victim,
    • his decision to arm himself and ignore Kelly’s attempt to stop him,
    • his firing of multiple shots specifically targeting the victim in a context where others were in the line of fire, and
    • his lack of remorse after the killing.
  2. Self-defense instruction. The district court correctly refused to instruct on self-defense. The evidence did not:
    • support a subjective fear of death or great bodily harm (as opposed to a simple beating), nor
    • support an objective finding that a reasonable person in Defendant’s position would have believed deadly force was necessary.
  3. Voluntary manslaughter instruction. The district court properly refused to instruct on voluntary manslaughter. There was no evidence that the victim sufficiently provoked Defendant; instead, Defendant was the initial aggressor who fired first. A killer cannot rely on the victim’s reasonable response to his own aggression as “provocation.”
  4. Defense of habitation instruction. Even though Defendant did not request a defense-of-habitation instruction at trial (making the claim unpreserved), the Court found:
    • No error in omitting the instruction, and
    • Thus, no fundamental error.
    There was no evidence that Defendant believed the victim intended to enter the home and commit a violent felony there, nor that such a belief would have been reasonable. The victim was lawfully on the property, never tried to enter the home, was unarmed, and was leaving.
  5. Ineffective assistance of counsel. Counsel was not ineffective for failing to request a defense-of-habitation instruction. Since the evidence did not support such an instruction, competent counsel was not deficient in failing to request it, and Defendant could not show prejudice under Strickland.

IV. Detailed Analysis

A. Sufficiency of the Evidence: Deliberate Intent to Kill

1. The governing standard

The Court begins, following well-established doctrine, by measuring sufficiency of the evidence against the jury instructions, which “become the law of the case.” (State v. Arredondo, 2012‑NMSC‑013, ¶ 18).

Under New Mexico law, evidence is sufficient if there is substantial evidence to support a verdict of guilt beyond a reasonable doubt on every essential element. (State v. Duran, 2006‑NMSC‑035, ¶ 5; State v. Sutphin, 1988‑NMSC‑031, ¶ 21). The Court:

  • views the evidence as a whole,
  • indulges all reasonable inferences in favor of the verdict, and
  • does not reweigh contrary evidence, because the jury is free to reject the defendant’s version of the facts. (Duran, ¶ 5; State v. Graham, 2005‑NMSC‑004, ¶ 13).

2. Deliberate intent under New Mexico law

To prove first-degree willful and deliberate murder under § 30‑2‑1(A)(1) and UJI 14‑201, the State must show that:

  • the defendant killed another person, and
  • did so with deliberate intent.

“Deliberate” means a decision “arrived at or determined upon as a result of careful thought and the weighing of the consideration for and against the proposed course of action.” The defendant must weigh and consider whether to kill and the reasons for and against it. While this deliberation can occur in a short period, a “mere unconsidered and rash impulse” is not enough, even if it includes an intent to kill. (UJI 14‑201).

3. How the Court found deliberate intent in this case

The Court identified several categories of proof from which the jury could infer deliberate intent:

  1. Animus toward the victim. Following State v. Smith, 1966‑NMSC‑128, ¶ 13, and State v. Guerra, 2012‑NMSC‑027, ¶ 29, the Court recognized that “animus of the accused toward the deceased” can evidence deliberation. Animus may be proven circumstantially through prior:
    • confrontations,
    • threats, or
    • other friction leading to violence. (State v. Tafoya, 2012‑NMSC‑030, ¶ 52).
    Here, animus was shown by:
    • Defendant’s firing of the victim from the renovation job after an argument,
    • his statements that the victim and siblings were “useless,”
    • his anger over Kelly allowing the victim to retrieve the cooler, and
    • his direct threat to Emili that she would “regret ever coming” to the property.
  2. Ignoring an opportunity to desist. Deliberation was further indicated by Defendant’s conscious choice to get the AR‑15 and ignore Kelly’s attempt to stop him. Kelly reached for his arm to prevent him from going outside with the rifle, and he “shrugged [her] off.” That moment provided an opportunity to reconsider—Defendant instead persisted.
  3. Use of deadly force directed at the victim. Once on the porch, Defendant fired nine rounds from an AR‑15, several toward Emili and the vehicle, but ultimately targeted the victim, hitting him twice in the chest and neck while he was only 10–30 feet away with his hands raised. The Court cited State v. Chavez, 2024‑NMSC‑023, ¶ 46, where the pattern and focus of shots were relevant to deliberation.
  4. Post-homicide lack of remorse. Echoing Guerra and Duran, the Court considered Defendant’s lack of remorse as circumstantial evidence of deliberation. In Guerra, the defendant’s statement, “I think I stabbed that fool seven or eight times,” supported an inference of deliberate intent. In Duran, the declaration that he had “murdered some b*tch” did the same. Here, Defendant:
    • laughed and told Emili “that’s none of your f***ing business” when asked about bullet caliber, and
    • described the victim’s family as “arrogant pricks” to law enforcement.
    The Court treated these as evidence that the killing was not a panicked, remorseful act but a considered decision consistent with hostility he had long expressed.

On this record, the Court held there was substantial evidence of deliberate intent and thus affirmed the first-degree murder conviction.

B. Jury Instruction Issues

A significant portion of the opinion addresses Defendant’s complaints about omitted jury instructions. This section of the decision provides particularly useful guidance on:

  • what it takes to get a self-defense instruction,
  • when voluntary manslaughter (heat of passion) is supported by the evidence, and
  • how New Mexico construes and limits the defense of habitation / castle doctrine.

1. Standards of review and general framework

The Court applies two interlocking frameworks:

  1. Preservation and standard of review.
    • Whether an instruction was properly denied is a mixed question of law and fact, reviewed de novo. (State v. Gaines, 2001‑NMSC‑036, ¶ 4).
    • The applicable standard of review depends on preservation:
      • Preserved challenges (where the defendant requested the instruction) are reviewed for reversible error. (State v. Benally, 2001‑NMSC‑033, ¶ 12; State v. Jernigan, 2006‑NMSC‑003, ¶ 10).
      • Unpreserved challenges (no request) are reviewed for fundamental error, applying a much stricter test. (Benally, ¶ 12).
    • Under either standard, the core question is whether a reasonable juror would have been confused or misdirected. (Benally, ¶ 12; State v. Parish, 1994‑NMSC‑073, ¶ 4).
  2. Evidence “in the light most favorable” to the requested instruction. When deciding whether a defendant is entitled to an instruction on a theory of defense or a lesser offense, the court must:
    • view the evidence in the light most favorable to giving the instruction, and
    • ask whether there is enough evidence such that reasonable minds could differ on the relevant elements. (Boyett, 2008‑NMSC‑030, ¶ 12; State v. Contreras, 2007‑NMCA‑119, ¶ 8).
    Even then, “failure to instruct the jury on a defendant’s theory of the case is reversible error only if the evidence at trial supported giving the instruction.” (Boyett, ¶ 12).

2. Self-defense instruction: why it was properly denied

a. Legal standard

Under State v. Lopez, 2000‑NMSC‑003, ¶ 23, a self-defense instruction is warranted when there is sufficient evidence that reasonable minds could differ as to:

  1. the defendant was put in fear by an apparent danger of immediate death or great bodily harm (subjective element);
  2. the killing resulted from that fear (subjective element); and
  3. the defendant acted as a reasonable person would act under those circumstances (objective element).

State v. Coffin, 1999‑NMSC‑038, ¶ 15, underscores that the first two elements are subjective—what the defendant actually believed and felt—while the third is objective—what a reasonable person would have done in those circumstances.

b. No evidence of a qualifying subjective fear

Defendant’s own statements to police were the primary support for his fear:

  • he was afraid the younger, taller victim would beat him up,
  • he saw the victim holding “something” in each hand, and
  • he claimed the victim continued to charge even after “warning shots.”

The Court drew on State v. Lucero, 2010‑NMSC‑011, ¶ 15, to emphasize that fear of a simple battery

  • Defendant believed the victim had a weapon, or
  • Defendant believed the items in the victim’s hands (a drink can and a phone) could cause death or great bodily harm.

A mere difference in size, the Court noted (citing State v. Duarte, 1996‑NMCA‑038, ¶ 10), is not, by itself, enough to establish a genuine subjective fear of death or great bodily harm. Nor was there any evidence that the victim had a reputation for such extreme violence or had previously inflicted such harm on Defendant.

Consequently, Defendant failed to demonstrate:

  • a subjective fear of immediate death or great bodily harm, and
  • that the killing resulted from such a fear.
c. Objective unreasonableness of Defendant’s conduct

The Court further held there was no basis to find that Defendant responded reasonably. Echoing Lucero and State v. Baroz, 2017‑NMSC‑030, ¶ 18, it emphasized:

  • Deadly force is justified only in response to a threat of death or great bodily harm (Lucero, ¶ 15);
  • When the supposed assailant is unarmed and there is no evidence of weapons, a belief in the need for deadly force is objectively unreasonable (Baroz, ¶ 18).

Applied to the facts:

  • Defendant initiated the confrontation by arming himself and firing “warning shots” toward the unarmed victim’s family and vehicle, at a time when the victim remained seated and nonthreatening.
  • When the victim finally exited, he:
    • was unarmed,
    • had his hands raised, and
    • said, “We’re leaving.”

Under these circumstances, no reasonable jury could find that a reasonable person in Defendant’s position would have believed:

  • that the victim posed a threat of death or great bodily harm, or
  • that shooting the victim multiple times with an AR‑15 was a reasonable response.

Thus, the Court held that Defendant was not entitled to a self-defense instruction, and the district court committed no reversible error by refusing it.

3. Voluntary manslaughter instruction: insufficient provocation

a. Legal standard

Voluntary manslaughter under § 30‑2‑3(A) requires:

  • a killing that occurs in the context of a sudden quarrel or heat of passion, and
  • provocation sufficient to negate the malice otherwise necessary for murder. (State v. Reynolds, 1982‑NMSC‑091, ¶ 8).

“Sufficient provocation” is defined in UJI 14‑222 NMRA as:

“any action, conduct or circumstances which arouse anger, rage, fear, sudden resentment, terror or other extreme emotions,”

provided that:

  • the provocation would cause an ordinary person of average disposition to lose self-control, and
  • an ordinary person would not have had time to cool off before acting.

Crucially, New Mexico follows the “general rule” that the victim must be the source of the provocation. (State v. Manus, 1979‑NMSC‑035, ¶ 16, overruled on other grounds). In State v. Gaitan, 2002‑NMSC‑007, ¶ 13, the Court held that a defendant who intentionally instigates an assault cannot rely on the victim’s reasonable response as “provocation” to reduce murder to manslaughter.

b. Defendant’s claim of provocation

Defendant argued that:

  • the victim “charged at him” after shots had been fired; and
  • there had been a prior argument between them about employment and property use.

But the Court found these claims legally insufficient:

  • The prior work-related argument occurred days earlier; any emotional impact would have cooled by the time of the killing.
  • The record showed that Defendant was the initial aggressor at the scene, firing multiple rounds with an assault rifle from the porch in the general direction of Emili and the vehicle, before the victim even stepped out.
  • When the victim did exit, he was unarmed, raised his hands, and announced that they were leaving—the opposite of conduct that would constitute “provocation” sufficient to inflame an ordinary person to kill.

Under Gaitan, a defendant cannot create the dangerous situation himself and then rely on the victim’s reasonable reaction as a mitigating factor. Here, any “charging” behavior by the victim arose in direct response to Defendant’s firing a rifle toward his fiancée and children. That reaction, if anything, was a reasonable attempt to shield others, not legally sufficient “provocation” originating from the victim.

Because Defendant could not point to evidence that the victim was the source of “sufficient provocation” as defined by UJI 14‑222, the Court held the district court properly refused to instruct on voluntary manslaughter.

4. Defense of habitation (castle doctrine): no evidence of an impending violent felony in the home

a. Preservation and standard

Unlike with self-defense and voluntary manslaughter, Defendant did not request a defense-of-habitation instruction at trial. The issue was therefore unpreserved and reviewed only for fundamental error under Benally, 2001‑NMSC‑033, ¶ 12.

Fundamental error applies only in “exceptional circumstances when guilt is so doubtful that it would shock the judicial conscience to allow the conviction to stand.” (State v. Cunningham, 2000‑NMSC‑009, ¶ 13). Before reaching that question, the Court first asks whether there was any error at all—i.e., whether the evidence could have supported giving the instruction. (Boyett, 2008‑NMSC‑030, ¶ 12; State v. Silva, 2008‑NMSC‑051, ¶ 11).

b. New Mexico’s defense-of-habitation doctrine

The Court relies heavily on:

  • State v. Boyett, 2008‑NMSC‑030, and
  • State v. Galindo, 2024‑NMSC‑004, ¶ 22.

These cases articulate that:

  • An occupant enjoys “significant latitude” in using force to defend the home (Galindo, ¶ 22), but
  • The use of deadly force is justified only if:
    • the defendant reasonably believed that the commission of a violent felony in the home was immediately at hand, and
    • it was necessary to kill the intruder to prevent that felony. (Boyett, ¶ 15).
  • “Felony” in this context is limited to violent felonies. (Boyett, ¶ 21).
  • A defense-of-habitation instruction (UJI 14‑5170) requires evidence sufficient for reasonable minds to differ as to all elements, including:
    • (1) the place was the defendant’s dwelling;
    • (2) it appeared to the defendant that a violent-felony commission in the dwelling was immediately at hand and killing the intruder was necessary; and
    • (3) a reasonable person in the same circumstances would have acted similarly.

Although actual entry is not strictly required, Boyett stresses that there must be an assault upon the home with intent to enter. Mere presence outside the dwelling, without evidence of an imminent breach, does not suffice.

c. Application to Defendant’s claim

It was undisputed that the house was Defendant’s dwelling, so the Court focused on elements (2) and (3).

  1. Subjective belief: no evidence of an imminent violent felony in the home.
    • Defendant argued he reasonably believed the victim intended to commit an aggravated battery (a violent felony) on him in the home.
    • The Court noted that, at most, Defendant’s own statements suggested a fear of being beaten up on the porch—not of an intrusion into the dwelling itself.
    • There was no evidence that:
      • Defendant believed the victim intended to enter the home, or
      • Defendant believed the victim intended harm to Kelly or Defendant’s daughter inside the house.
    Under Boyett, the absence of any belief in an intended intrusion or violent felony inside the home defeats the second element of defense of habitation.
  2. Objective reasonableness.
    • The victim was not an “intruder” in the classic castle doctrine sense:
      • Kelly had invited him (through Emili) to retrieve the cooler;
      • He never attempted to enter the house;
      • He only exited the vehicle after Defendant fired multiple shots toward his family;
      • He raised his hands and said, “We’re leaving”; and
      • He had no weapons or tools to force entry or commit a violent felony inside.
    • As in Boyett (¶ 23), where there was no evidence the victim was attempting to force entry, the Court found no objectively reasonable basis to infer the victim was about to invade the home or commit a violent felony inside.

With no evidence supporting either the subjective or objective components, the Court held there was no error—much less fundamental error—in not giving a defense-of-habitation instruction.

Because none of the instruction issues had merit, the Court also rejected any claim of cumulative error, citing State v. Saiz, 2008‑NMSC‑048, ¶ 66 (“where there is no error to accumulate, there can be no cumulative error”), later clarified on other grounds in State v. Belanger, 2009‑NMSC‑025.

C. Ineffective Assistance of Counsel (IAC)

1. The Strickland framework

The Court evaluated the ineffective assistance claim under the familiar two-pronged test of Strickland v. Washington, 466 U.S. 668 (1984), as adopted in New Mexico:

  1. Deficient performance. Counsel’s performance must fall below an objective standard of reasonableness—counsel must have failed to exercise the skill of a reasonably competent attorney. (Duncan v. Kerby, 1993‑NMSC‑011, ¶ 10; State v. Paredez, 2004‑NMSC‑036, ¶ 13).
  2. Prejudice. There must be a reasonable probability that, but for counsel’s errors, the outcome would have been different. (State v. Trammell, 2016‑NMSC‑030, ¶ 23, quoting Strickland).

A failure to establish either prong defeats the claim. (Guerra, 2012‑NMSC‑027, ¶ 23; State v. Reyes, 2002‑NMSC‑024, ¶ 48).

2. Application to failure to request a defense-of-habitation instruction

Defendant argued that trial counsel was ineffective for not requesting a defense-of-habitation instruction. The Supreme Court rejected this argument on the first prong (deficient performance):

  • As already explained in the jury instruction section, the evidence did not support a defense-of-habitation instruction: there was no proof that Defendant believed the victim intended to enter the home and commit a violent felony, nor that such a belief would be reasonable.
  • Competent counsel is not expected to request instructions that are unsupported by the evidence. Not making such a request is not deficient performance.

Because Defendant failed to show counsel acted below a reasonably competent standard, the Court did not need to reach the prejudice prong, and the ineffective assistance claim failed.

V. Precedents and Doctrinal Threads

Although Ricoy is unpublished and nonprecedential, it is doctrinally significant as a synthesis of several important New Mexico precedents:

  • Deliberate intent and animus/lack of remorse.
    • Smith, Guerra, Duran, and Chavez collectively establish that:
      • prior hostility and threats,
      • manner of the attack (e.g., multiple focused shots), and
      • post-crime boasting or indifference
      are powerful circumstantial indicators of deliberate intent. Ricoy applies this line of cases squarely in a domestic/family context.
  • Self-defense and the threshold of “death or great bodily harm.”
    • Lopez, Coffin, Lucero, and Baroz are reaffirmed:
      • The subjective fear must be of death or great bodily harm, not mere physical injury;
      • Simple battery or generalized fear of a fight is insufficient;
      • Where the supposed assailant is unarmed, the objective reasonableness of using deadly force is highly suspect.
  • Voluntary manslaughter and sufficient provocation.
    • Reynolds, Manus, and Gaitan provide the framework applied in Ricoy:
      • Provocation must come from the victim;
      • It must be serious enough to unhinge an ordinary person’s self-control;
      • And the killer cannot instigate the confrontation and then rely on the victim’s defensive response as mitigation.
  • Defense of habitation / castle doctrine.
    • Boyett and Galindo are central: they limit the defense to circumstances where:
      • a violent felony in the dwelling is believed to be immediately at hand, and
      • deadly force is truly necessary to prevent it.
    • Ricoy underscores that:
      • lawful visitors or invitees are not “intruders” simply because the defendant dislikes them;
      • no “assault upon the home” is present if the person remains outside and does not attempt entry; and
      • castle doctrine is not a free-standing license to kill adversaries or disliked relatives near one’s home.
  • Jury instruction framework and error review.
    • Gaines, Boyett, Benally, Parish, Cunningham, and Silva shape the procedural foundation:
      • Evidence is viewed in the light most favorable to the requested instruction;
      • Preserved errors are reviewed for reversible error; unpreserved ones for fundamental error;
      • Ultimately, the concern is whether the jury was confused or misdirected.
  • Ineffective assistance of counsel.
    • Strickland, Paredez, Kerby, Trammell, and Reyes are reaffirmed as the controlling framework.
    • Ricoy illustrates a basic but important point: failing to pursue a meritless defense or an unsupported instruction is not deficient performance.

VI. Impact and Practical Implications

A. For criminal practitioners

  • Prosecutors.
    • Ricoy confirms that evidence of:
      • prior statements of hostility,
      • threats before the incident,
      • deliberate rearming and ignoring pleas to desist, and
      • post-crime lack of remorse
      can powerfully buttress proof of deliberate intent for first-degree murder.
    • In domestic contexts, prosecutors can expect courts to treat family or quasi-family victims similarly to strangers when analyzing self-defense and castle doctrine claims, where the defendant is the first aggressor.
  • Defense counsel.
    • Self-defense and voluntary manslaughter instructions require a concrete evidentiary foundation:
      • For self-defense, evidence must show of death or great bodily harm, not a generalized fear of a fight, and a plausible basis (weapons, prior violent acts, etc.) for that fear.
      • For voluntary manslaughter, evidence must show victim-originated provocation that would unhinge an ordinary person and that had not “cooled.”
    • With castle doctrine / defense of habitation:
      • Be prepared to show evidence of the victim’s intended entry into the home and a perceived imminent violent felony inside, not merely a confrontation at the doorstep or in the yard;
      • Absent such evidence, requesting the instruction may be futile.
    • On ineffective assistance:
      • Ricoy reinforces that appellate courts will not deem counsel ineffective simply for failing to request a legally and factually unwarranted instruction.

B. For trial judges

  • The decision helps clarify the boundary lines for when instructions on:
    • self-defense,
    • voluntary manslaughter, and
    • defense of habitation
    are supported by the evidence. Judges can rely on Ricoy’s analysis—backed by published authorities—to deny instructions when:
    • the defendant is clearly the first aggressor;
    • the victim is unarmed and objectively nonthreatening; or
    • there is no evidence of an imminent violent felony in the home or of victim-originated provocation.

C. For the development of New Mexico law

While Ricoy is unpublished and not generally citable as precedent under Rule 12‑405 NMRA, it illustrates how the Supreme Court currently applies a set of mature doctrines:

  • First-degree murder via deliberate intent,
  • Self-defense limitations,
  • Heat-of-passion voluntary manslaughter,
  • Castle doctrine / defense of habitation, and
  • Ineffective assistance of counsel.

It is especially notable for its firm stance that castle doctrine cannot be stretched to validate shooting an unarmed, retreating or non-intruding family member on or near the property, even when the defendant claims fear and anger over perceived disrespect or prior conflict.

VII. Simplifying Key Legal Concepts

For non-lawyers, several technical concepts recur in this opinion. In simplified terms:

  • Deliberate intent (first-degree murder). The law distinguishes between:
    • killing someone in a sudden, impulsive moment, and
    • killing after at least some mental weighing of whether to kill.
    “Deliberate intent” does not require a long plan; it only requires that the person actually thought about killing and decided to go through with it, even briefly.
  • Self-defense.
    • A person may lawfully use force, including deadly force, if they:
      • truly believe they are in immediate danger of being killed or seriously injured, and
      • their belief and reaction are reasonable under the circumstances.
    • Fear of being punched or in a normal fistfight, by itself, is usually not enough to justify killing.
  • Voluntary manslaughter (heat of passion).
    • This is a lesser form of homicide where the killer acted in the heat of strong emotions—anger, rage, terror—triggered by the victim’s actions.
    • The victim must have done something seriously provocative that would make an average person momentarily lose self-control.
    • The law does not allow you to start a fight and then claim the other person’s reasonable reaction as “provocation” that excuses or reduces your crime.
  • Defense of habitation (castle doctrine).
    • New Mexico recognizes a strong right to defend one’s home, but it is not unlimited.
    • You may use deadly force only if:
      • you reasonably believe a violent felony inside your home is about to occur, and
      • killing the intruder is necessary to stop it.
    • The doctrine generally applies to intruders or attackers trying to force their way in—not to invited guests or family members who are outside and trying to leave.
  • Reversible error vs. fundamental error (jury instructions).
    • Reversible error: If the defendant asked for an instruction and the court wrongly refused it, and that refusal likely misled the jury, the conviction can be reversed.
    • Fundamental error: If the defendant never asked for the instruction, the conviction is only reversed in especially extreme cases, where the error is so serious that it calls the fairness of the entire trial into question.
  • Ineffective assistance of counsel.
    • Defendants are entitled to competent legal representation.
    • To win an IAC claim, they must show:
      • their lawyer’s work fell below reasonable professional standards, and
      • that this likely changed the outcome of the trial.
    • Not asking for a legally unsupported instruction is not poor lawyering—it is appropriate.

VIII. Conclusion

State v. Ricoy does not break new doctrinal ground, but it powerfully illustrates the current contours of several crucial doctrines in New Mexico homicide law:

  • First-degree murder via deliberate intent can be proven from a combination of:
    • prior hostility,
    • deliberate arming and continuation of an attack despite opportunities to stop, and
    • callous post-killing remarks.
  • Self-defense is tightly constrained: fear of a beating or generalized anxiety does not justify deadly force, especially when the victim is unarmed, raising his hands, and announcing intent to leave.
  • Voluntary manslaughter requires victim-originated “sufficient provocation.” A defendant who starts the violence cannot turn the victim’s response into a mitigating factor.
  • Defense of habitation, although robust in principle, is limited to situations involving an imminent violent felony in the home. Family members or invitees lawfully present outside the dwelling do not become “intruders” simply because the homeowner objects to their presence.
  • Ineffective assistance claims cannot be built on counsel’s refusal to advance meritless or unsupported defenses.

As a nonprecedential decision, Ricoy cannot ordinarily be cited under Rule 12‑405 NMRA, but it remains an important window into how the Supreme Court of New Mexico understands and applies its homicide, self-defense, and castle doctrine jurisprudence to high-conflict domestic situations. The opinion serves as a clear warning that New Mexico courts will strictly police the evidentiary boundaries of defensive theories and will not permit them to be used to shield what is, in substance, an unprovoked or grossly disproportionate use of lethal force.
