The three companies mentioned have together maybe up to 50k employees (quick internet search, don't quote me on that). 11 of them (various roles, some out of the game for years) dying or going missing over many years in a country with a pretty high criminality and suicide rates rates doesn't sound very surprising.
Out of 50k people? These specific of backgrounds and scenarios of their death/disappearence? No. That is surprising. Any statistics you'd find about the rates of any one or more of these kinds of disappearances are going to be population level, averaged out over groups that are much higher risk and therefore skew the average rates to seem higher than their priors actually dictate for many sub populations, eg, working…
I'm genuinely curious if you found any data to support it especially when you add JPL, Los Alamos National Laboratory, MIT, Caltech, and the Kansas City National Security Campus to the list, over four years.
And what puts an even bigger question mark on the whole thing is that the FBI embarked on this whole thing after being asked by members of the House Committee on Oversight and Government Reform when they read about it in the newspaper. How critical are these people and how surprising their final fate if the US needs a tabloid to ring the alarm?
