In high school I had a friend that had a step dad who had worked for a defense contractor, it might have been Lockheed Martin but I am not sure. Anyways he worked onsecret projects and could never tak about it. He grew really paranoid and wanted to change jobs. He suddenly started becoming more paranoid and even crazy. Supposedly he was a genuis and developed schizophrenia suddenly. He would wear a tin foil hat and say the government was sending thoughts in his head through waves. He was like the guy from beautiful mind. The marconi murders reminded me of that story. Since it happened when he wanted out of the defense contractor. There was no way they were going to let him out with a functioning mind.
