The repair work is an illegal business. Marty puts all the money he received in one checking account. One day a police officer comes to have his car fixed. He walks into Marty's shop to give him the keys when he sees a car that he believes matches the description of a stolen car. The police officer snaps a picture of the car and shows it to the person who reported the car stolen. What crimes has Marty committed? If the police officer never obtained a search warrant, can the picture of the stolen car be used at trail?
