People v. Riley: Circumstantial Evidence and “Natural and Probable Consequences” Permit an Intent-to-Kill Inference for Accessorial Second-Degree Murder; Strategic Avoidance of Inconsistent Defenses Is Not Ineffective Assistance

1) Introduction

In People v Riley (2026 NY Slip Op 04669 [4th Dept July 24, 2026]), the Appellate Division, Fourth Department unanimously affirmed a Monroe County Court judgment convicting Adriel Riley, Jr.—a juvenile offender after a nonjury trial— of murder in the second degree (Penal Law §§ 20.00, 125.25[1]).

The appeal raised two central questions:

  • Legal sufficiency / weight of the evidence: whether the People proved intent to kill beyond a reasonable doubt, where the proof was largely circumstantial and the People’s theory permitted liability either as a principal or under accessorial liability (Penal Law § 20.00).
  • Effective assistance of counsel: whether counsel was ineffective for failing to introduce evidence that defendant had “low average” intelligence for a 14-year-old and a learning disability, in support of a diminished culpability theory.

The Fourth Department’s memorandum is primarily an application of established doctrine, but it is significant for how it synthesizes (i) the sufficiency and weight review standards in a circumstantial, nonjury homicide case, (ii) the “natural and probable consequences” inference of intent, and (iii) the deference given to counsel’s strategic choice to avoid inconsistent defenses—especially in a juvenile-offender context.

2) Summary of the Opinion

The Fourth Department held that the evidence—viewed in the light most favorable to the People—supported a rational inference that defendant either actively participated in, or intentionally aided, an intentional killing accomplished by dousing the victim in a flammable liquid and setting him on fire. The court emphasized video evidence, incendiary materials recovered from the apartment, defendant’s admissions placing him at the scene, evidence of intimidation of the burning victim, and defendant’s false exculpatory statements to police and to his codefendant.

The court also rejected the ineffective-assistance claim, reasoning that counsel reasonably pursued a “did not participate” defense and that introducing evidence aimed at diminished culpability (infancy/mental culpability) would have risked inconsistent defenses.

Finally, the court found the sentence not unduly harsh or severe.

3) Analysis

A. Precedents Cited

(i) Legal sufficiency in circumstantial evidence cases

The court anchored its sufficiency analysis in the familiar “valid line of reasoning and permissible inferences” standard: People v Hines, 97 NY2d 56, 62 (2001), rearg denied 97 NY2d 678 (2001), reiterated that even in circumstantial cases, the question is whether any rational factfinder could reach the verdict based on the proof when viewed most favorably to the People. The Fourth Department applied the same approach reflected in People v Hancock, 229 AD3d 1229, 1230 (4th Dept 2024), lv denied 42 NY3d 1020 (2024).

The “light most favorable” lens was reinforced by People v Contes, 60 NY2d 620, 621 (1983), which is routinely cited to emphasize that appellate sufficiency review does not reweigh proof or resolve credibility conflicts.

(ii) Accessorial liability and inference of intent

For acting-in-concert principles, the court quoted Penal Law § 20.00 and relied on People v Scott, 25 NY3d 1107, 1109-1110 (2015), and People v McDonald, 172 AD3d 1900, 1901 (4th Dept 2019), for the proposition that criminal liability attaches where a defendant, with the required mental culpability, intentionally aids another’s commission of the offense.

The opinion then turns to how intent may be proven: McDonald, 172 AD3d at 1901-1902, and People v Hough, 151 AD3d 1591, 1593 (4th Dept 2017), lv denied 30 NY3d 950 (2017), support inferring intent from conduct and surrounding circumstances. Critically, the court invoked the “natural and probable consequences” inference: People v Barboni, 21 NY3d 393, 405 (2013), and later People v Stackhouse, 194 AD3d 113, 119 (4th Dept 2021) (internal quotation marks omitted), to justify an inference that a defendant intends the ordinary results of his actions.

The court also cited People v Engles, 243 AD3d 1238, 1239 (4th Dept 2025), lv denied 44 NY3d 1065 (2026), and “see generally” People v Rumble, 58 AD2d 900, 902 (3d Dept 1977), affd 45 NY2d 879 (1978), to situate this inference within longstanding New York doctrine.

(iii) Distinguishing “mere presence” from participation

The court relied on People v Hancock, 229 AD3d at 1231, to reject a “mere presence” characterization of defendant’s role, contrasting it with People v Slaughter, 83 AD2d 857, 857-858 (2d Dept 1981), affd 56 NY2d 993 (1982), which stands as a benchmark for cases where presence and proximity do not suffice absent evidence of shared intent or assistance.

To describe the probative force of the circumstantial proof, the court cited People v Williams, 233 AD3d 1463, 1465 (4th Dept 2024), lv denied 43 NY3d 1012 (2025), and People v Brown, 204 AD3d 1390, 1393 (4th Dept 2022), lv denied 39 NY3d 985 (2022), for the notion of a “compelling chain of circumstantial evidence” that excludes reasonable innocent explanations.

(iv) Weight of the evidence (nonjury trial framing)

For weight review—particularly in a bench trial—the court invoked People v Danielson, 9 NY3d 342, 349 (2007), and “see generally” People v Bleakley, 69 NY2d 490, 495 (1987), emphasizing the two-step inquiry: whether an acquittal would have been unreasonable and, if not, whether the factfinder failed to give the evidence the weight it should be accorded. The Fourth Department’s conclusion that “an acquittal would not have been unreasonable” but the verdict still must stand tracks Danielson/Bleakley’s deference to factfinding where the record supports the chosen inferences.

The court cited People v Hickey, 171 AD3d 1465, 1465-1466 (4th Dept 2019), lv denied 33 NY3d 1105 (2019), as a recent Fourth Department exemplar applying that framework.

(v) Fire/accelerant homicide cases supporting intent-to-kill inferences

In rejecting the argument that intent to kill was not proven, the court “see generally” cited: People v Exford, 234 AD3d 1252, 1252-1253 (4th Dept 2025); People v Burton, 215 AD3d 1054, 1059 (3d Dept 2023), lv denied 40 NY3d 927 (2023); and People v Truitt, 213 AD3d 1145, 1149-1150 (3d Dept 2023), lv denied 39 NY3d 1144 (2023). These citations function as doctrinal support that setting a person on fire—particularly with accelerant—can sustain an inference of intent to kill given the obvious lethality and foreseeability of death.

The court’s “only reasonable conclusion” language drew support from People v Rackover, 239 AD3d 447, 448 (1st Dept 2025), lv denied 44 NY3d 1013 (2025), and the Fourth Department’s own People v McGuire, 227 AD3d 1499, 1499-1500 (4th Dept 2024), lv denied 42 NY3d 971 (2024), illustrating that circumstantial cases may properly culminate in a conclusion of exclusive culpability (alone or acting in concert) where alternative explanations are not reasonable on the record.

(vi) Ineffective assistance and the risk of inconsistent defenses

On ineffective assistance, the court leaned on the principle that counsel may reasonably avoid inconsistent theories. People v McFadden, 161 AD3d 1570, 1572 (4th Dept 2018), lv denied 31 NY3d 1150 (2018), quoted for the “hazardous nature of pursuing inconsistent defenses,” and People v Nauheimer, 142 AD3d 760, 761 (4th Dept 2016), lv denied 28 NY3d 1074 (2016), cited consistently with that proposition.

The court characterized counsel’s choice as focusing on defendant’s actus reus (nonparticipation) rather than mens rea (infancy/diminished culpability), citing People v Kohmescher, 228 AD3d 1334, 1335 (4th Dept 2024) (see generally), and reaffirming the deferential standard that reasonable strategy—even if unsuccessful—is not ineffective assistance: People v Ritchie, 239 AD3d 1262, 1264 (4th Dept 2025), lv denied 44 NY3d 994 (2025), and People v Singleton, 203 AD3d 1671, 1672-1673 (4th Dept 2022), lv denied 38 NY3d 1074 (2022).

(vii) Additional cited authority

The memorandum also cited People v Bredt, 248 AD3d 1791, 1794-1795 (4th Dept 2026), as another contemporary application of Danielson’s “valid line of reasoning” phrasing in reviewing proof of elements.

B. Legal Reasoning

(i) Why the evidence supported intent to kill

The defendant’s principal appellate claim was narrow: even if he was present, the evidence allegedly did not establish that he had the intent to kill required for Penal Law § 125.25(1) (intentional murder). The Fourth Department’s response is methodical: it identifies a set of interlocking circumstances from which a rational factfinder could infer intent.

  • Weapons/scene evidence: video from the codefendant’s phone depicting defendant “wielding a shotgun” in the victim’s apartment minutes before the victim was set on fire; recovery of “multiple lighters and bottles of ignitible liquid, including charcoal starter fluid.”
  • Presence at the burning: defendant admitted he was present in the apartment when the victim was on fire.
  • Expert causation evidence: a fire investigator opined the victim was intentionally ignited with “an open flame and combustible materials.”
  • Post-incident conduct probative of culpability: defendant watched the victim burning outside without rendering aid; after passersby extinguished the flames, defendant approached the severely injured victim and attempted to intimidate him to lie about the identity of the person who doused and ignited him.
  • False exculpatory statements: defendant lied to police about a “crackhead” fleeing after setting the victim on fire.
  • Consciousness-of-guilt admissions in custody: a recording captured defendant yelling to the codefendant that he told police a different person did it; that he and the codefendant “tried to help him”; that they could get “30 years” if police learned what happened; and that he would not “fold[ ]” because he was “too street for that.”

These facts do double work. First, they support the inference that defendant did more than observe: he either acted as a principal or intentionally aided the codefendant. Second, they support the key mental-state inference: if one participates in or intentionally assists dousing a person with accelerant and igniting him, the natural and probable consequence is death—making intent to kill a permissible inference.

(ii) Accessorial liability as a pathway to intent

By invoking Penal Law § 20.00 and cases like People v Scott and People v McDonald, the court made clear that the People did not need to prove defendant personally struck the match (so to speak). They needed to prove he acted with the requisite mental culpability and intentionally aided the homicidal conduct.

The court’s analysis reflects a common pattern in New York acting-in-concert cases: when direct proof of the final act is uncertain, the combination of (1) presence at the critical time, (2) association with implements or instrumentalities, (3) conduct consistent with joint action, and (4) consciousness-of-guilt behavior can provide the “permissible inferences” needed to satisfy both conduct and mental-state elements.

(iii) Distinguishing sufficiency from weight (and why both challenges failed)

On legal sufficiency, the question was whether any rational factfinder could find intent beyond a reasonable doubt. The court found the circumstantial chain “compelling” and not reasonably explained by innocence or mere presence.

On weight of the evidence, the court used the Danielson/Bleakley approach: it acknowledged that “an acquittal would not have been unreasonable,” but still concluded the trial court did not err in its assessment of how much weight to assign the People’s proof. This is a key doctrinal point: an appellate court may recognize that competing interpretations existed while still affirming because the factfinder’s chosen inferences were reasonable and supported by the record.

(iv) Why counsel’s omission was deemed strategic, not deficient

Defendant argued counsel was ineffective for not introducing cognitive/learning-disability evidence. The court reframed this as an attempt to pivot from a “he didn’t do it” defense to a “he lacked the mental capacity/culpability” defense.

Relying on People v McFadden and People v Nauheimer, the Fourth Department treated the shift as an invitation to present inconsistent defenses—which may confuse the factfinder and undermine credibility. It held that counsel reasonably chose to focus on actus reus (nonparticipation) rather than mens rea (infancy/mental culpability). Under People v Ritchie and People v Singleton, that strategic choice, grounded in the circumstances and evidence, did not amount to ineffective assistance.

C. Impact

Although the decision does not announce a novel doctrinal test, it is likely to be cited for several practical propositions in future cases:

  • Intent-to-kill can be inferred from an accelerant-and-ignition killing method under the “natural and probable consequences” principle, especially when paired with post-event intimidation and false exculpatory statements.
  • Accessorial liability remains fact-driven: contemporaneous video, incendiary tools, and coordinated post-crime conduct can bridge gaps where direct evidence of the final act is contested.
  • Bench trial appeals will continue to face layered deference: sufficiency review remains People-favorable, and weight review—while broader— will not result in reversal where the trial judge’s inferences are reasonable even if acquittal was plausible.
  • Ineffective-assistance claims premised on not presenting diminished-capacity-style facts may be difficult where counsel pursued a coherent nonparticipation theory and the proposed evidence would introduce tension or inconsistency in the defense narrative.

4) Complex Concepts Simplified

Legal sufficiency
A minimal constitutional/legal threshold: whether a rational factfinder could find each element proved beyond a reasonable doubt based on the evidence, viewed most favorably to the People.
Weight of the evidence
A broader, New York-specific review: the appellate court considers whether the verdict was against the weight of credible evidence. Even so, it generally defers to the factfinder’s ability to see and hear witnesses and to choose among reasonable inferences.
Circumstantial evidence
Proof by inference rather than direct observation of the ultimate fact (e.g., no one testifies “I saw him light the victim”), but a set of facts (implements, timing, conduct, statements) makes that conclusion reasonable.
Accessorial liability (Penal Law § 20.00)
“Acting in concert”: you can be guilty of the offense committed by another if, with the required mental state, you intentionally assist (solicit, request, command, importune, or aid) the commission.
Intent and “natural and probable consequences”
Intent is usually proven indirectly. If someone engages in conduct that ordinarily leads to death (e.g., dousing a person in accelerant and igniting), a factfinder may infer intent to kill because death is the predictable outcome.
Actus reus vs. mens rea
Actus reus is the criminal act (what was done). Mens rea is the mental state (what was intended/known). Counsel here chose to contest the act (nonparticipation) rather than argue reduced mental culpability.
Inconsistent defenses
Defenses that pull in opposite directions (e.g., “I wasn’t involved” and “if I was involved, I didn’t have the mental capacity/intent”). Courts often regard counsel’s decision to avoid such tension as a reasonable strategic choice.

5) Conclusion

People v Riley reaffirms that, in New York, a conviction for intentional second-degree murder—whether as a principal or under Penal Law § 20.00— may rest on a tightly woven circumstantial record where the method of killing and surrounding conduct support an inference of intent to kill. The decision also underscores appellate restraint in bench-trial weight review and reinforces that counsel’s choice to pursue a consistent, coherent nonparticipation defense—rather than introduce mental-capacity evidence that could create inconsistent theories—will often be treated as legitimate strategy, not ineffective assistance.
