Background
Cory Bromley arranged to visit Kyle Tifft at Tifft’s Alcester home for a drug transaction in the early morning of March 1, 2025. About 13 minutes after Bromley arrived, two masked, armed men entered the home. One, Damion Williams, robbed Tifft of his wallet and cash and shot him in the head, grazing his scalp. The men also assaulted Tifft’s girlfriend and fled.
The State alleged that Bromley aided and abetted Williams. Its circumstantial evidence included Bromley’s arrangements that brought him to Tifft’s home, evidence supporting an inference that he transported Williams and the second intruder there, his flight from the house after the shooting, and his later communications and assistance to Williams as Williams prepared to leave the area. A jury convicted Bromley of first-degree burglary, first-degree robbery, second-degree kidnapping, commission of a felony while armed with a firearm, and petty theft.
The Court’s Holding
The South Dakota Supreme Court affirmed all convictions. Viewing the evidence and reasonable inferences in the State’s favor, the Court held that a rational jury could find Bromley intentionally aided Williams’s crimes rather than merely being present at the scene.
The Court held that aiding and abetting first-degree robbery required proof that Bromley had advance knowledge that a dangerous weapon would be used. The evidence—including Bromley’s recent handling of Williams’s guns and the inference that he drove the masked intruders to the home shortly before the armed robbery—permitted the jury to find that knowledge. The same evidence supported the burglary, kidnapping, firearm-felony, and theft convictions.
Key Takeaways
- Circumstantial evidence may establish both an aider and abettor’s conduct and intent.
- For aiding and abetting first-degree robbery, the State must prove advance knowledge that a dangerous weapon would be used.
- Presence, companionship, and conduct before and after an offense may support an inference of accomplice liability when considered together.
Why It Matters
The decision applies the requirement that an accomplice possess the mental state for the full charged offense, including advance knowledge of firearm use in an armed robbery. It also illustrates the breadth of evidence a jury may use to infer participation in a planned crime, even without direct proof of the underlying agreement.
