How can I gain access to a Facebook account of a deceased family member?
Is there a procedure or appropriate channels we must go through via Facebook in order to gain access to the account of a dead family member?
Facebook will not allow anybody to access a deceased user's account.
You can submit requests for deceased family members' accounts through Facebook's help center:
If the deceased user is involved with an ongoing investigation, law enforcement can contact Facebook to request additional information relevant to the investigation. Most information requires a court order.
