Tosa died unexpectedly from a cause that is still unknown.

If you don't want to give money to charity for whatever reason, I of the Storm's suggestion to register as a bone marrow donor is an excellent alternative. I think he would also appreciate it if you did a blood donation to the Red Cross in his remembrance.

His family wishes their privacy to be respected. I understand the questions for a pic or his first name or something to show a bit of the human being behind the internet persona, but I'm not in a position to give any kind of that information, sorry.
