Do you know of cases like this? If so then can you answer a few more questions.
Yes
Had this person been DFed or in real danger of being DFed or whatever the equivalent is if they were never baptized?
No, she was in good standing and liked by most in the Hall.
Would you consider that any shunning of the person might have pushed a person over the edge?
She was never shunned.
What status did they have in the cong - baptized or not, elder, MS, woman, minor, active or not, any abuse issues, possible discipline coming up. . .
She was baptized for perhaps 15 years.
She was a very beautiful woman of the age 29 or 30 at the time of her suicide. Her JW husband left her for another christian sister several years earlier. He was DF but quickly reinstated the same year. She was severely depressed and would comfort herself with booze. Her sister lived beside her and went in her house to find her nude hanging from a rafter.
This happened I believe in 1999 or early 2000. So sad and what a waste of life. I left the religion shortly afterwards so I have not much knowledge of other suicides.
