Devon Bradley is an actor who played a fake old man/FBI agent/con artist in a scam to fool Homer and Bart. He caught them trying to take money of the residents of the Springfield Retirement Castle while undercover as a resident, so he took them to prison. Whilst they were in prison he sardonically drove off in their car so Homer and Bart had to make up a story which ended up in Groundskeeper Willie getting arrested. He then came back in the court scene, driving Homer's car right into the courtroom, where it was announced that he was just an actor.
