Are the missing or dead scientists all connected?

No, not credibly anyway. President Trump hinted this week that something sinister may lurk behind the disappearance or death of 10 government workers tied to sensitive nuclear or space technology, but those close to the various investigations into the disparate cases say they see no links. "I just left a meeting on that subject, so pretty serious stuff," Mr. Trump told reporters Thursday. "Hopefully, coincidence... but some of them were very important people, and we are going to look at it." "The deaths and missing persons cases are scattered across several years at different and only loosely affiliated organizations," said Joseph Rodgers, the deputy director of the Project on Nuclear Issues at the Center for Strategic and International Studies. "If all of the scientists were working on one project or weapons system, then I'd be more suspicious." Caption from article by Anna Schecter, Daniel Klaidman, and Callie Teitelbaum, CBS News.
