I don't have proof other than this from his friend on deviantart and someone using his AIM account claiming to be his sister, but Addison Sengco aka Genetic Freak passed away on Jun 27th from Pancreatic Necrosis.
Addison was a great friend and will be missed greatly by those lucky enough to have known him. never having a bad word to say to anyone, Addison was always optimistic and fun to speak with. Always ready to give anyone a chance and expand on the group of people in the twentysomething's thread to leave a legacy of sorts on the internet. He was always proud of that thread and the people who helped make it what it is. I know people were worried about him and his safety due to the bad weather in his country and it is very sad to find out it was much worse.
R.I.P Addison.

: Osias Addison Sengco put up a good fight but it seems fate has decided that he has had enough- he passed away early this morning.
I am now feeling both sad and happy. Sad that someone as young as him(he's barely 30) should go, but also happy that he ain't suffering anymore and I had at least got to see him one last time. Kung nasaan ka man Ade, mami-miss ka namin.
