Well, apparently my list is too lengthy because when I responded to this thread and finally submitted my answer it was deleted! This time I'll make it short.

Motor vehicle accident: family friend while vacationing in Rome, Best friend's brother drag-racing, two friends who happened to be brothers hit eachother head-on and died at the scene( no people, I am not making this up), my Grandma killed by drunk driver who happened to be my aunt (no, again...not making this up), and a friend of mine killed bike-riding...his father was the fireman answering the call to find out it was his son who had died (again...not making this up)

Fire: Uncle (he was a fireman)

Suicide: Cousin (Viet Nam vet)

Murder: Close friend (her husband murdered her and then dismembered her, leaving her body parts in several trash dumpsters. This was a particularly difficult one for me and still find it hard to talk about).

Others you didn't ask about would be from illness. I have lost in the last few years one of my brothers (45) from a heart-attack, my uncle from a heart-attack, my cousin (40) from cancer, My sister's twins (the boy died before birth and the girl died at 4 days old), and then the most heart-wrenching was my own daughter who died two years ago in October...I still can't talk about it...
