I would have to say, "Apparently, yes."
As a University of Florida junior I had a very lovely, sweet girl for a roommate, but she struggled in school and went home to Jacksonville, where she had a whirlwind courtship with an older, divorced man who was possessive. We began to fall out of touch because of our living 90 miles apart, and the odd dynamics and demands of her marriage.
A few months later I was called by her younger sister, to say my friend had shot herself to death. As a group of her college friends, we attended the services in Jacksonville, where the younger sister pulled me aside and told me she wasn't certain it was a suicide, but there was no solid proof otherwise.
Disturbs me on many levels to this day.
