I also remember reading that woman do not successfully suicide as often as men. I believe it is rare in woman.(w/o looking up the exact numbers)
also she is recorded saying she will not suicide more than once but Dan Moldea is the person being quoted in the press as telling him she would do it. Those quotes of her saying "I can't go back to prison, I'll kill myself" don't line up with the recorded quotes from her where she shows herself to be a tough individual.
Why did they hang her then? Probably some symbolic reason and also more traumatizing to the people who know she didn't do it herself. There's a card in the tarot of a hanging man I think, maybe some symbolism to that.
Also Moldea did a good book 20 years ago about game fixing in the NFL but after that they must have gotten to him and now he is not to be trusted,imo.
