I grew up with a boy who's older sister committed suicide her sophomore year in high school by starting her car in the garage.
6 years later, my friend hung himself in his basement.
I often wonder how parents can handle losing a child in this way, but 2? How devistating!
I'm sorry for the loss of your friend. That would be awful, losing both children, especially to suicide. It seems like when it happens once, the likelyhood of other members of the family doing it goes way up.
