Well. I was going to explain this to you.. but then it got interrupted in chat.
Facebook has a contact form that you can submit the information about a deceased person.
It asks for their name, their birthday, the email they used for the account, any networks they were in, the URL of their page, your relationship to the person, whether or not you want the page memorialized or deleted, proof of death [obituary or news article link] and any additional information you want to give them.
I did this for my best friend/ex’s account.
They emailed me back about two days later.
We are very sorry to hear about your loss. Per our policy for deceased users, we have memorialized [Name’s] account. This removes certain sensitive information and sets privacy so that only confirmed friends can see the profile or locate it in Search. Additionally, the profile will no longer appear in the “Suggestions” section of the home page. The Wall, however, remains so that friends and family can leave posts in remembrance.
