John Bailey (defendant) and another man stood in the vicinity of the Center Market Provision Company (the Company), a wholesale meat distributor, for most of an afternoon until an employee of the company exited the building with $4,200 in a bag to be deposited at the bank. The other man approached the Company employee and robbed him of the money at gunpoint. Bailey was approximately 10 feet away at the time. When another Company employee yelled that a robbery was occurring, Bailey and the other man ran away in the same direction. Bailey was charged with aiding and abetting the robbery. The other man was never identified or apprehended. At trial, Bailey unsuccessfully sought a judgment of acquittal on the ground that the prosecution failed to prove its case beyond a reasonable doubt. Bailey was convicted and he appealed.
