Hickengruendler:

I'm sorry, I haven't got the book at hands and can't look for a quote, 
but I'm sure that, after he and Harry return from the Pensieve scene 
involving Mrs Smith, Dumbledore mentions, that after Hebzibah's death 
the family finds out, that the cup and the locket have disappeared, 
meaning Tom has stolen and/or hidden them.
