Boeing whistleblower John Barnett alleged in a lawsuit prior to his death in South Carolina that he was "harassed" and "humiliated" for speaking out at work.
The killer would have had to kill him in his car, wrap his hands around the gun to establish fingerprint marks. A company like Boeing that's part of the Military-Industrial Complex wouldn't have an issue finding a highly trained contract killer.
Bribes at the local authority level (maybe higher too) to have them rule it a suicide with no further investigation needed. No need for further pesky questions.
Now all I'm waiting on is for the judge to toss out his incomplete testimony since it isn't complete.
Then just wait a few weeks until the media focuses on other things.
Then the execs can have martinis while stock number go up.
