So, the guy was expected to appear in court for thw second round of questioning and when he didn't show up was found dead in his truck in the underground car park of the hotel. Doesn't sound like someone that wanted to end it. Maybe I'm wrong but I wouldn't book a room to go to court and then on a whim decide to end it.
Most people that kill themselves do so on a whim. Its probably not the case, but its not impossible. I'm guessing either the coroner is corrupt, or they have actual evidence it was a suicide. If it was a murder, then I doubt Boeing would do it without assurance it couldn't be traced back to them. So regardless of what actually happened, the only official story there will ever be is that it was a suicide. That is, unless Boeing is as reckless about murder as they are about building planes.
Absolutely, I don't mean there is no warning whatsoever. There is almost always a history of depression, but that history is not always visible to loved ones, let alone the public. I just mean they are likely not specifically planning to commit suicide until soon before they do it, which at least in my experience is true
Yeah it could emerge apparently at random for unsuspecting familiars, but this guy was about to do something that was important for him, on which he worked for years according to the article. Sounds sus to me.
