bboy_mn:
Good catch; I hadn't thought of that before.

I think maybe Dumbledore just put the pieces of the puzzle together,
although he did so based more on intuition than actual evidence.

Harry said to Dumbledore as the went out to find Crouch Sr. 

"...said he's (Crouch) done something terrible... he mentioned his son..."

Now comes a part where I make a great leap. I have to assume
Dumbledore questioned Harry in more detail than is indicated in the
book. The next day, Harry said to Hermione-

" ...he seemed to think his wife and son were alive..."

Although, in context, that related more to his delusions, but if
Dumbledore did question Harry in detail then he knows some of the
stuff that Harry is saying to Hermione. That gave him a clue that
somehow Crouch Sr's son is involved. 

Also, Dumbledore seems to have a strang/odd way of knowing thing. In
most cases, especially if they have to do with Harry, he knows more
than the available information would indicate. Whether he is gazing
into an enchanted crystal ball or if he has a strong psychic intuitive
sense, or what, I don't know.

I can fantasize ways of explaining it, but you have, in a sense,
brought up something that doesn't have an explaination; at least, no
obvious explaination. 

Just a few thoughts.
