Nobody. Someone wins a lottery jackpot then their child gets kidnapped and all the money goes to the 'nappers to pay ransom. Eventually the nappers get caught and go to jail but they've spent all the money so nobody has gained anything.
Wait, not yet. Just calling in the tip to the police isn't enough; they have to actually catch you in the act in order for me to qualify for all of the reward money. (Oops, did I say that out loud?)
