SAN FRANCISCO (CBS SF) – Just hours after a “Goodby” letter surfaced from the man at the center of an FBI manhunt and explosives investigation, Ryan Chamberlain apparently returned to social media to deny federal claims that he is armed and dangerous.

“Nothing they’re reporting is true. No “Stashes.” Not “armed and dangerous.” No Car “Rigged to explode.” I explored some ugly websites, a year-ish ago. I was depressed,” Chamberlain told friends on Facebook.

Prior to that note, and an accompanying Twitter message, it was not clear that Chamberlain was still alive after recently disappearing. Over the weekend explosive materials were found during an FBI raid of Chamberlain’s apartment at Polk Street and Van Ness Ave. Earlier Monday, a letter appearing explaining Chamberlain’s state of mind popped up on his Facebook page. That note claimed to be previously written and time-released. It chronicled relationship, financial and emotional troubles he had dealt with in recent years, referring in several instances to the “dark times” he had dealt with.

Chamberlain did not post any threats in that note, but expressed remorse to friends about the developments in his life.

“I’m so sorry about this. I’m sure this will completely blindside you all,” the note reads.

The FBI has confirmed that they have read that document, but have not commented further. KCBS Radio obtained a copy of the document through an online acquaintance of Chamberlain.
