POOR GRAMMAR on the way...
I know 3 people who committed suicide. One prominent thing they had in common. It was never simple 1+1. Their loved ones and friend found out much later the layers of problems that lead to the tragic act. All were deeply troubled or in need of (mental) help they either did not seek or didn't know they should have had
So that takes me to think John Coughlin did not take his own life exclusively because of the allegations and investigation he was facing, public opinions of people of him when those allegations became public knowledge. I do not have any exclusive knowledge of these allegations against him, or his true character. And I think this is true for pretty much everybody else, or wast majority of people sharing their opinions online regarding these pieces of news.
His life was not over for that investigation taking place, or him being made to resign from his position at MK blades ect. His life would have changed for sure, but how - now we will never know. This would have disturbed his life for sure, but a reasonable person can see there was also possibility he would have been cleared of the charges he called unfounded. Witch hunt for people spreading information that is of public record is appalling.
