Someone steals Bob's bike in 2010.
In 2020 Bob finds it for sale. It's too late to prosecute for theft, so the police wouldn't bother.
Of course Bob doesn't know if the seller was the thief. The bike could have changed many hands in 10 years. But Bob wants to find the thief and get compensated via a civil claim and/or publicly name/shame them.
Bob may not care about the bike now anymore (it can be in horrible condition). But he wants to track down the thief and sue them for damages (depriving of using the bike which was almost new when stolen).
Can Bob get the court to subpoena the seller to reveal where the bike came from, and then subpoena all revealed previous owners too?
