In light of what has happened, my i suggest that zoltans family recieve this money no matter what. The last thing people need at times like this is money worries or such alike. Be they poor or rich, i think it is obvious that zoltan would have wanted them to be looked after, safe and secure. If zoltans dad chooses otherwise i think that is his decision, the person who knew him best knows who should recieve this money.
R.I.P ZOLTAN
