Bava Metzia 39 - Caring for a Captive's Property (Finds)

If someone is held captive, can a court allow a relative to live on and use his property? If a rumor circulated or one witness testified that the captive died, then the court can. The relative stands to inherit, so he will be careful with the property. What if his whereabouts are unknown?
