Background

Michael Biggs cashed a $12,610.60 check shortly before spending time with Brandon Beckman. Casino footage showed Biggs leaving a casino on January 13, 2022, with Beckman and Robert Harvel. Later that morning, witnesses encountered two men freeing a car stuck near an access road; one wore Beckman’s distinctive mohawk-fringed cap. Biggs’s body was found near that road the next day, with a close-range gunshot wound to the head. Evidence at the scene indicated that his body had been moved and covered with a blanket and snow.

Harvel, who faced charges arising from the same events, testified under use immunity that Beckman shot Biggs, took cash from him, and made Harvel help move and conceal the body. Beckman moved to dismiss at the close of the State’s case, arguing that Harvel’s testimony lacked the independent corroboration Montana law requires for accomplice testimony. The jury later convicted Beckman of felony murder and tampering with physical evidence.

The Court’s Holding

The Montana Supreme Court affirmed. It held that independent circumstantial evidence sufficiently tended to connect Beckman to both the robbery resulting in Biggs’s death and the concealment of Biggs’s body, as required to corroborate Harvel’s testimony.

The court relied on the sequence of events: Beckman left the casino with Biggs and Harvel; Beckman was independently placed at the access road where the killing and concealment occurred; Beckman gave changing accounts of his contact with Harvel; and evidence showed Biggs’s clothing had been disturbed and Beckman had substantial cash and expenditures afterward. For tampering, the court held that Beckman’s presence and conduct at the scene, the physical evidence of concealment, his later conduct, and his question about whether the body was buried in snow together supported an inference that he participated in concealing the body. Considering Harvel’s testimony with the corroborating evidence, a rational jury could find both offenses beyond a reasonable doubt.

Key Takeaways

  • Accomplice testimony need not be independently sufficient to prove guilt; independent evidence need only tend to connect the defendant to each charged offense.
  • Circumstantial evidence, including a defendant’s inconsistent statements, movements, access to money, and physical-scene evidence, may provide the required corroboration.
  • Corroboration of one offense does not automatically corroborate another, but the same independent circumstances may support separate inferences for both offenses.

Why It Matters

The decision underscores that Montana’s accomplice-corroboration rule is a threshold safeguard, not a requirement that prosecutors prove every element without the accomplice. Once independent evidence connects the defendant to the offense, the jury may weigh the accomplice’s account with all other evidence.

It also highlights the importance of tying corroborating facts to each conviction separately, particularly where the State alleges both an underlying violent felony and later concealment of evidence.
