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.
True, but I get the point. Like it’s hard for those of us with souls to comprehend the sheer evil it takes to murder or coerce-to-murder someone’s father/husband/brother/friend, and then tell them through your teeth “That’s so unfortunate this thing happened to them. Thoughts and prayers.”
