## Facts

- Four men unlawfully entered the office-warehouse of Martin Oil Service, Inc. in Chicago, pushed a safe out a second-floor window into the yard, and left to get help because it was too heavy to move.
- An employee discovered the break-in around 11:45 p.m., saw the safe in the yard, and called police; officers waited at the scene until about 2:15 a.m.
- Around 2:15 a.m., a Cadillac and a Ford arrived, each carrying three men; the Cadillac backed toward the safe with its trunk open.
- Police called out; the men fled; police gunfire killed one man and wounded Richard Zierlion.
- Evidence showed the original four men later met Zierlion and another man at a tavern and enlisted their help to move the safe.
- The record contained no evidence that Zierlion participated in the initial entry or in pushing the safe out of the building.

## Issues

1. Whether evidence that a defendant assisted in moving a safe after it had been removed from a building is sufficient to convict him of burglary as a principal without proof he entered the building or shared the felonious intent at the time of entry.

## Decision

- The Supreme Court of Illinois reversed the burglary conviction and set aside the sentence.
- The court held the State failed to prove an essential element of burglary as to Zierlion: entry into a building with intent to commit a felony.
- The court concluded that Zierlion’s conduct, at most, constituted accessory after the fact, which is a separate offense and cannot sustain a burglary conviction.

## Legal Principles

- Burglary requires proof that the accused entered (or aided and abetted entry into) a building with intent to commit a felony.
- Aiding or assisting during the commission of the crime can render a person liable as a principal, but assistance rendered only after the burglary is complete does not.
- Proof that a defendant was an accessory after the fact proves an independent offense and cannot substitute for proof of the charged burglary.

## Conclusion

Because the evidence showed only that Zierlion was recruited to help move the safe after it was already outside the building, and did not show participation in or intent at the time of entry, the State did not meet its burden on burglary; the conviction was reversed.
