I have some friends in the industry who have shared some stuff, not really obscure or dark but one comes to mind. Years before he came out, I knew BA was gay. Well, they told me about it but I didn't believe them 100%. I was a little shocked but equally sad, that if it was true, he had to live his life in secret. There's about two more that I was told about, that I think they will come out in due time. I just hope that these two other individuals aren't hurting and come out when they are ready.
Another one was about Joey Poiriez. His grandma lived in my area and we'd see him at our local park from time to time. I was just about a year or two younger than him but had heard about his drug usage. I was pretty naive back then and didn't put two and two together. Some years later, word got around that he had died, except he hadn't. Then some years passed and I heard the same news, except this time he really did overdose.
