Yes, I can safely say that I have known three I am sure of and a fourth I am leaning towards thinking he did the same because of the circumstances surrounding his death at 21 years of age. The other three ALL were having difficulty staying to the rigid "WTS requirements"; one was DFed and another had just come back to the JW fold. One was a longtime "study" that had an alcohol problem but appeared to be conquering it and then went home and shot himself right after an elder's meeting. There was another suicide of a recently DFed lady that occured a couple of months before I moved here so I never knew her. They ALL had that one link.....they were either had been IN the WTS and were now out....or they were studying......and all these are from a very small area here in the boondocks.
My heart goes out to all of them and the families they left behind that now have to cope with their deaths.
