Background

Six officers went to Robert Lee Chavez’s home to execute an arrest warrant. After speaking with an officer at the door, Chavez shut the door, broke a front window from inside, lit fuses, and threw three suspected explosive devices through the window toward the officers over about thirty seconds.

The devices detonated, producing smoke and debris. The officers testified that they feared for their safety. A jury convicted Chavez of three counts of dangerous use of explosives, six counts of assault on a peace officer, and one count of resisting, evading, or obstructing an officer.

The Court’s Holding

The Court of Appeals held that the three dangerous-use-of-explosives convictions violated double-jeopardy protections against multiple punishments for the same unitary conduct. The explosives statute does not clearly define its unit of prosecution, so the rule of lenity applied. Chavez’s three deployments were not sufficiently distinct: they occurred during one continuous thirty-second episode, from the same location, toward the same general area, without intervening events.

The court therefore reversed and remanded with instructions to vacate two of the three explosives convictions and resentence Chavez. It affirmed the remaining convictions. Separate assault convictions were proper because Chavez’s conduct caused six individual officers to reasonably fear an immediate battery. The prosecutor’s improper “golden rule” remarks were brief and cured by instruction, and the evidence supported the convictions.

Key Takeaways

  • Three explosive devices used in one uninterrupted thirty-second episode supported only one dangerous-use-of-explosives conviction.
  • Assault on a peace officer is victim-based when multiple officers are placed in reasonable apprehension of immediate battery.
  • Brief improper closing remarks did not require a mistrial where the court gave an approved curative instruction and the defendant was not deprived of a fair trial.

Why It Matters

The decision applies New Mexico’s unit-of-prosecution analysis to dangerous use of explosives and confirms that ambiguity in the statute is resolved through lenity. Prosecutors must establish sufficient factual distinctness before charging separate counts for multiple explosive devices used in a single continuous event.

At the same time, the opinion preserves separate assault convictions for each officer placed in fear, even when the threatening conduct is part of one incident.
