Must a child who stole candy from a store at the age of ten return what he stole after he has grown up and feels remorse, especially since he is in another country?

The thief's liability is not discharged except by returning the value of the stolen goods to the store owner, and he is not required to inform him of the theft. The money can be sent by any possible means. If it is impossible to return the money, then it should be given as charity on behalf of the owner.
