4 right off the top of my head. Thinking about it just now I realized they were all kids of acting elders at the time.
One hung himself off a bridge during morning traffic, so many saw him die. Another one raced his motorcycle in front for a lady driving a minivan, he had been DF'ed at the time and his step mom had told him to never call them again unless he wanted to come back to Jehovah, and the last elders son I do not know how he killed himself but my husband and I were invited to the parents house for dinner after a talk and though their son had been dead for over two years the elder dad broke down crying while we were there, it was horribly sad.
The girl who killed herself had been sexually abused by someone in the hall and it had been swept under the rug. No two wittiness's to the crime and the girl was told just to forget about it and move on, she OD"ed on sleeping pills when she was in her early 20's. The aunt was upset at the girl for killing herself saying that the pedophile said he was sorry what else could he have done. He is still in good standing in the hall.
I am sure there are others but not popping into my head as quick as these. All of them were under the age of 30.

As a side not I was horribly depressed when I was pioneering and thought about suicide a lot while out in service. We lived in the country and drove a ton just aimlesslyhardly ever talking to anyone. I used to wonder if I slit my wrists while I was sitting in the back seat of my own car as sisters were not allowed to sit in the front if there were brothers in the car group they always had the front seat where I lived. Anyway I digress, I used to wonder if anyone would notice or care for that matter if I bleed out including my husband. I still think they would have been happy to have me die.
Looking back I was horribly depressed and hate being alive, yet I was doing the most important work there is trying to drag others in to this cult, save lives.
