having filed for bankrupts several days prior to his theft blog post i doubt there is any funds to pay a bounty, and if it was paid post bankruptcy it would have to be returned.
just give the info to authorities.
I must be paid for my work since I've incurred expenses tracking this down. I'm sure something can be worked out since he was the one to make the 1k btc offering in the first place.
Why not just give it to them or make it public at least you helped the Bitcoin community and maybe if their loss can be recovered, maybe you'll get a reward, not only from them but from others who also have interest in this issue.
