Patterson was on a group vacation tour when he discovered that his camcorder was not where he had left it on the tour bus. Later on the tour, Patterson noticed another vacationer, Carlsen, with a similar camcorder. When Carlsen was confronted, he claimed that he had found the camcorder at one of the tour bus stops. When Patterson produced a bill of sale with a serial number that matched the one on the disputed camcorder, Carlsen refused to surrender it, claiming that since he had found it, it was his. Will Patterson be able to regain possession of his lost camcorder?
