From a blog -

i called and called and called and called because i didn't think he'd really do it, and thought maybe he was just fucking with me by not answering. a day passed. last night his friends called me at 10oo and told me it was all my fault, that he had been taken off life support/ i feel emersed in guilt if it was. but i think he had very hard life perhaps, and there were a lot of things i didn't know. DID I PULL THE TRIGGER?
