(AP Photo/ FBI) (Newser) – A well-known public relations consultant in San Francisco is now the target of a nationwide manhunt after police found explosives in his apartment. The agency says Ryan Kelly Chamberlain II, 42, should be considered armed and dangerous and may be in possession of more explosives, USA Today reports. He was last seen south of San Francisco yesterday, driving a white 2008 Nissan Altima with California or Texas license plates, reports NBC. Police, hazmat teams, and federal agents spent 14 hours searching Chamberlain's residence yesterday and witnesses say some devices were exploded at the scene. Chamberlain was well-known in the city's political circles and worked on many campaigns, focusing on social media, the San Francisco Chronicle finds. "I'm worried about the guy," the founder of Barbary Coast Consulting says. "I'm hoping this ends without anybody getting hurt. I'm flabbergasted that this seems to be taking place." A former colleague says Chamberlain "got weird" after losing his job at a sports marketing company last fall. "There was a lot of strange behavior since November," he says. "He stopped answering his phone. I think he became an extreme introvert."
