John Barnett had worked for Boeing for 32 years, until his retirement in 2017.
In the days before his death, he had been giving evidence in a whistleblower lawsuit against the company.
Boeing said it was saddened to hear of Mr Barnett’s passing. The Charleston County coroner confirmed his death to the BBC on Monday.
It said the 62-year-old had died from a “self-inflicted” wound on 9 March and police were investigating.
Sometimes reporters get details of the story wrong. I don’t know what’s so strange about that.
Bit of a lack of professionalism there.
Crime journalists write what the cops say. Blame the source, not the messenger.
That’s…a bit of a lack pf professionalism too. Way too common now.
