Cashiers check stale who gets the money?

An eccentric man has cashiers checks drawn to himself instead of keeping it in a bank or having cash. the man keeps just enough money in his account to keep it open. the man lists his brother as the POD beneficiary. the man dies. the man has no will, no wife, no children and thus his estate passes to his parents. the cashiers checks are lost. after 90 days the funds are set to reverse. who gets the funds once the 90 days passes? the parents or the brother?
