When an officer goes to a business to pick up a shoplifter who is already in the custody of private security guards, the officer should take specific steps in order.
Officer O'Brien is dispatched to the Blue Moon Art Gallery to pick up a shoplifter. When she arrives, she talks to Jeffrey, the store security guard, who tells her that he watched a man pick up a five-inch long statue, stuff it in his coat pocket, and walk out the front door of the shop. He chased the man down and brought him back to the store. Jeffrey took her into the back room where he gave her a photograph of the statue for her to turn in as evidence. Officer O'Brien searched the prisoner for weapons and then placed him in the patrol car, seatbelting him in securely. They drove straight to the jail where O'Brien booked the suspect for shoplifting.

II. improper, because she did not take the statue itself in as evidence
