John Barnett, a former Boeing employee who filed a whistleblower report alleging safety issues, was found dead in his truck on March 9, 2024. The autopsy report released on Friday determined the cause of death as a gunshot wound to the head and the manner of death as ‘suicide’ due to the presence of a ‘suicide note’ in the vehicle. Police are still investigating Barnett’s death, but the autopsy report suggests he was experiencing personal distress and had a history of mental health issues.
