I hope everyone can comment with more reasoning and less assumptions. I'm trying my best to calm down and attempt to get more information about the hacker, because he also used my email for a credit card fraud case. It's possible to discover something at that direction.
I have also listed a few people who know this secret email of mine. And I'm going to question them one by one tonight.
I'm definitely on the side of Bitcoinica customers and I believe that if the real hacker really had ties with me personally like what MagicalTux said, I may be able to recover majority of the amount back if the hacker can be warned. This issue is very serious and if I'm the hacker, I would definitely return the full amount back to reduce the criminal punishment.
The hacker seems to be a Chinese because he used Chinese punctuations in his English messages in the Aurumxchange ticket.
I will provide any information needed to the police once Bitcoinica files a police report.
