I think therein lies the discomfort a lot of people feel about this sort of thing. Should the funds go to the living expenses of the parents? It's a big question.
Personally, I think yes, at least for the first few months, as I cannot imagine going back to work as usual while my child was lost/stolen. But others have an image of the parents "profiting," which makes them uncomfortable.
(In actually, I think that is fairly wrong, as I can't see them selling enough merch to pull a "profit." MOO.)
I kind of wish an external foundation would sell the t-shirts and bracelets and funnel the money to the search, etc. I think this might help alleviate the tension people feel about this issue.
