## Facts

- James Gray and Michael Burk traveled from Oakland to Redding intending to rob Marjorie Beeman of valuable jewelry.
- Burk gained entry by posing as a poll taker; Gray followed wearing a ski mask.
- The men restrained the victim with tape and bindings, ransacked the house, stole jewelry and silverware valued over $100,000, and cut telephone wires.
- Timothy Mark Beeman was not present during the crimes but was arrested six days later with several stolen rings.
- The prosecution claimed Beeman helped plan the robbery by providing information about the home, its contents, and how to enter, and that he offered to sell stolen jewelry for a share of proceeds.
- Beeman testified he did not want to be involved and lacked any intent to help the robbery; he claimed he held jewelry only to return it and provided information that helped lead to Gray’s and Burk’s arrests.
- The trial court instructed the jury with then-standard CALJIC Nos. 3.00 and 3.01 on aiding and abetting and refused Beeman’s requested modification requiring a finding that he intended his acts to aid the crimes.

## Issues

1. Whether aiding-and-abetting liability requires proof that the defendant acted with the intent or purpose of encouraging or facilitating the target offense, in addition to knowledge of the perpetrator’s unlawful purpose.
2. Whether CALJIC No. 3.01, as given, erroneously permitted conviction based on knowledge and assistance without requiring intent to aid.
3. Whether the instructional error was prejudicial where intent was the central disputed issue.

## Decision

- The California Supreme Court reversed Beeman’s convictions.
- The court held CALJIC No. 3.01 (as then formulated and given) misstated the mental-state requirement for aiding and abetting by omitting the intent-to-aid element.
- The court concluded the error was prejudicial because the case turned on whether Beeman intended to facilitate the crimes, and the jury’s request for clarification reflected confusion on that point.

## Legal Principles

- Aiding and abetting requires proof that the defendant (1) knew the principal’s unlawful purpose and (2) acted with the intent or purpose of committing, encouraging, or facilitating the commission of the target offense.
- It is insufficient that the defendant knew of the crime and performed acts that in fact assisted; the assistance must be rendered with the purpose of furthering the offense.
- Jury instructions on aiding and abetting must require a finding of the defendant’s subjective intent to aid, promote, encourage, or instigate the commission of the crime; omission of this element is legal error.
- Where intent is the principal disputed element and the instructions allow conviction on a lesser mental state, the error is prejudicial and requires reversal.

## Conclusion

The court held that aider-and-abettor liability in California demands both knowledge of the perpetrator’s unlawful purpose and a concurrent intent to encourage or facilitate the offense, and it reversed because the jury was not properly instructed to find that intent.
