My detective never trusts any of the clues, because they are always wrong. He's arrested my playable sims before, but they've never been trapped in the jail cell. Usually they just go home the next day.
Try playing your other sims at home for a while and see if the prisoner goes home on their own, or from the neighbourhood screen, click any community venue instead of a household and choose the Visit button. It will pop up a list of sims to choose from - try the imprisoned sim to send them to a community lot.
