The FBI and other federal agencies are investigating the deaths and disappearances of more than a dozen top scientists and personnel tied to NASA, Los Alamos Nation Laboratory and  classified military research.   The remains of Los Alamos worker Melissa Casias were found in Carson National Forest  nearly a year after she vanished. Police records revealed that missing retiree Anthony Chavez had been researching quantum physics with a Los Alamos scientist.  

In the meantime the February disappearance of retired Air Force General William Neil McCasland,  continues. McCasland had links to many of the dead and missing who were connected to classified  aerospace and national security programs.  

Conspiracy theories abound on a coordinated effort to silence these researchers. Do any of them have a hold on reality?
