Bava Kamma 68: The Timeline of Despair
Selling a stolen animal and the penalty incurred during the time when the owner is or is no longer hoping to get the animal back - subject to a machloket on whether the despair of the owner getting the animal back. The extra 4 and 5 payment only kicks in once the theft is "forever." After despair, the thief takes full possession, and the original owner is compensated. There is an important discussion here regarding whether the animal is sold or slaughtered. Plus, note R. Sheshet's view and R. Nachman's view. Also, a clearly articulated dispute between R. Yochanan and Resh Lakish - until the reasons for their dispute are put through the wringer, and nothing is clear anymore. Including why a thief (and also an owner) would consecrate a stolen animal.
