Authorities in South Carolina have released the findings of their investigation into the death of John Barnett, a whistleblower who had filed a complaint against Boeing. Barnett, a former employee of the company, was found dead in his truck with a gunshot wound to his head outside a hotel in Charleston on March 9.

The investigation report states that there was no evidence of forced entry or a struggle inside the vehicle. Additionally, the key fob for Barnett's truck was found in his pocket. The Charleston County Coroner's Office has ruled his death as a suicide.

Barnett, who had worked for Boeing for 32 years, had filed a whistleblower complaint alleging safety concerns. The United States Department of Labor was in the process of investigating his claims before his death and is scheduled to hold hearings on the matter in June.

According to the police report, Barnett was found with a silver Smith and Wesson handgun in his hand, and ballistics confirmed that the bullet recovered at the scene had been fired from the same gun. It was also revealed that Barnett legally purchased the weapon. A note written by Barnett was found in the passenger seat, expressing his frustration with Boeing and whistleblower protection.

The report highlighted Barnett's history of mental health challenges, including symptoms of post-traumatic stress disorder, anxiety, and intrusive thoughts. Friends and family members have shared that Barnett had been under severe stress due to ongoing legal battles and a perceived hostile work environment at Boeing.

Barnett's concerns about safety issues at Boeing's factory in South Carolina were previously reported in the media. He had revealed quality issues and potential risks, such as discarded metal shavings near flight controls and faulty oxygen systems on the 787 jetliner. Boeing denied these allegations.

The investigation also revealed details about Barnett's activities before his death. Security footage showed him entering his hotel room alone the day before and leaving alone after an hour. His truck was later seen parked at the hotel until the next morning when police arrived for a wellness check.

Boeing expressed sadness over Barnett's passing and extended condolences to his family and friends. The company emphasized that it had addressed quality concerns raised by Barnett during his tenure.

The investigation report shed light on the series of complaints made by Barnett as he alleged whistleblower retaliation and a hostile work environment. Court documents revealed instances where Barnett was penalized for raising concerns and faced obstacles in his career progression.

The discovery phase of the Department of Labor's investigation is set to be completed by March 30, with formal hearings scheduled for the week of June 24. Attorneys representing Barnett released documents detailing the alleged "gaslighting campaign" and retaliation their client faced at Boeing.

As the investigation into John Barnett's death concludes, questions remain regarding the circumstances surrounding his extensive complaints against Boeing and what impact they may have had on his mental well-being.
