Despite various rumors, there is no way of retrieving deleted messages on Facebook. Immediately after you delete a message in your private Inbox, you are given the option to "Undo" - above the message - but that is it. Once a message is gone, it's gone; there is no way to recover it later.
Currently, you cannot recover a deleted post.

Police may be able to access deleted Facebook messages if they have a valid legal warrant or subpoena. However, Facebook's data retention policies mean that deleted messages are typically not stored long-term, and the company may not retain them after a certain period.

Ultimately, the ability to retrieve such messages depends on Facebook's data handling practices and the specifics of the investigation.
