N.J..com reports that a man contacted police last Thursday to say the cards, a train set and an antique bowl had been taken sometime in the last three weeks. He had last been inside on February 3.
Why he left those items behind isn't clear and the story says he didn't give police any information on specific cards that were missing, only that there were signs of a break-in--or more--when he came back for them.
So far, there are no suspects in the case.
