My son has taken his own life. There was no note and none of his friends (he had many) can answer why. Is it possible to access his Facebook account? There might be some hint as to his mind frame. I know he was on Facebook an hour before he took his life.
As noted in the Facebook FAQ:
So it looks like Facebook won't facilitate access. Unless there is a legal route to gaining access, you're best chance may be if you can get access to the email account (or possibly mobile phone) associated with the Facebook account. Then you can go through the password reset process to gain access.
