Vern is in divorce proceedings in Florida. His address and lawyer's address should be there in the paperwork. Put an outline describing the information you have and as much as you can divulge into a legal envelope and mail it with confirmed delivery. Save the receipt. Also mail yourself a copy which you keep sealed in case you later have to prove the paper trail on sending them the info. Send a copy to Vern's/Cryptsy's lawyers. Inform them that you expect the 1000 BTC reward IF YOUR INFO TURNS OUT TO GET THE COINS BACK. Negotiating for 30 per cent or for upfront payment will be unrealistic. After you get the money back in Cryptsy's wallet you should get the 1000btc. The bounty was publicly posted. If you get the coins returned then they'll have the money to pay 1000 btc reward.
That's my opinion on it anyway. I'm not from Cryptsy so can't personally guarantee anything.
