The Boeing whistleblower who died last week from an apparent suicide left his driver’s license in his hotel room and a possible suicide note in the passenger seat of his truck, the police report revealed. 

John Barnett, 62, was in Charleston, South Carolina, where he was finishing a deposition part of a whistleblower retaliation lawsuit against the jet company where he worked for 32 years as a quality-control manager. On the morning of March 9, he was set to appear for the last day of his deposition, where he was raising concerns for the quality of Boeing’s products; instead, Barnett was found dead with “self-inflicted wounds” in his truck outside of a Holiday Inn he had been staying at, according to a report from the Charleston Police Department.
