Boeing whistleblower John Barnett found dead days after testifying against company

The whistleblower who publicly raised doubts about Boeing's production standards was found dead.

The Charleston County Coroner's Office told Fox News Digital that John Barnett, 62, died from what appeared to be a self-inflicted gunshot wound on Saturday. Barnett was cross-examined by Boeing's lawyers and his own attorney days before he died.

The court planned for Barnett to answer more questions on Saturday, but he did not appear as planned. 

The BBC reported that he was later found dead in his truck, which was parked in a hotel parking garage.
