## Facts

- Ronald Sexton, age fifteen, shot and killed seventeen-year-old Alquadir Matthews during an argument in a vacant lot.
- A witness heard Matthews tell Sexton there were no bullets in the gun; Sexton challenged him and a single shot fired, killing Matthews.
- Evidence indicated the pistol had a defective magazine and required manual chambering; with the magazine removed, a round in the chamber could not be confirmed without pulling the slide.
- Sexton claimed the gun discharged while he examined it and that he relied on Matthews’s assurance it was unloaded; Sexton had no prior experience owning or firing a gun and did not check whether it was loaded.
- Sexton was charged with purposeful/knowing murder and firearm offenses; the jury acquitted on murder, aggravated manslaughter, and possession for an unlawful purpose, but convicted of reckless manslaughter and unlawful handgun possession.
- The Appellate Division reversed the reckless-manslaughter conviction, finding (1) an unsupported murder charge created a risk of a compromise verdict and (2) the jury instructions failed to place on the State the burden to disprove Sexton’s mistake-of-fact claim beyond a reasonable doubt.

## Issues

1. Whether a defendant’s mistake of fact (belief the gun was unloaded) can negate the mental state of recklessness required for reckless manslaughter.
2. Whether, when a mistake-of-fact theory would negate recklessness, the State must disprove that theory beyond a reasonable doubt and how the jury should be instructed.
3. Whether it was reversible error to charge purposeful/knowing murder absent credible evidence of intent, given the risk of distorting the jury’s consideration of lesser-included offenses.

## Decision

- The New Jersey Supreme Court affirmed the Appellate Division and left the reversal of the reckless-manslaughter conviction in place.
- The Court held a mistake of fact may defeat a recklessness-based offense when the mistake prevents proof that the defendant consciously disregarded a substantial and unjustifiable risk.
- The Court agreed that the jury should not have been charged on purposeful/knowing murder because the evidence did not credibly support an intent to kill or cause serious bodily injury, and the charge risked a compromise verdict on reckless manslaughter.
- The Court approved requiring jury instructions that connect mistake of fact to the State’s obligation to prove recklessness beyond a reasonable doubt.

## Legal Principles

- No conviction may stand unless the State proves each element of the offense, including the required mental state, beyond a reasonable doubt.
- A mistake of fact is not merely an independent affirmative defense; it can negate an element of the offense by making proof of the required culpability impossible.
- For crimes requiring recklessness, a faultless mistake, and in some circumstances a merely negligent mistake, can negate recklessness; a reckless or grossly unreasonable mistake does not negate recklessness and may support liability.
- When a defendant presents evidence of a mistake that, if credited, would negate recklessness, the State must disprove that mistake beyond a reasonable doubt (including by proving the defendant’s belief or failure to verify the risk was itself reckless).
- Trial courts should not submit higher-culpability charges to the jury without evidential support, because unsupported charges can improperly influence deliberations on lesser-included offenses.

## Conclusion

The court held that mistake of fact may negate the recklessness element of reckless manslaughter and must be addressed through instructions that preserve the State’s burden to prove recklessness beyond a reasonable doubt; it also held that charging unsupported murder was reversible error because it risked a compromise verdict on the lesser offense.
