A year prior to Laura's murder, Cooper witnesses missing FBI Agent Phillip Jeffries appear in Cole's office before mysteriously disappearing again. He then investigates the disappearance of Agent Chester Desmond, who went missing while tasked with solving the murder of Teresa Banks, but finds only the words "Let's Rock" written on the windshield of Desmond's car. Later, Cooper confides in Agent Albert Rosenfield that he suspects Teresa's murderer will strike again, correctly describing Laura as the killer's next victim, but Rosenfield rebuffs Cooper's prediction.
