On August 12, Mr. and Mrs. Mitchell, the owners of a small secondhand store, attended Alexander’s Auction, where they bought a used safe for $50. The safe, part of the Sumstad estate, contained a locked inside compartment. Both the auctioneer and the Mitchells knew this fact. Soon after the auction, the Mitchells had the compartment opened by a locksmith, who discovered $32,207 inside. The Everett Police Department impounded the money. The city of Everett brought an action against the Sumstad estate and the Mitchells to determine the owner of the money. Who should receive the money? Why?
