one guy who i was pretty cool with, and seemed relatively healthy dropped dead of a heart attack at 43. that's the one who shocked everyone the most.

another girl in her late 40s was by chance in an accident, and after a CATscan they found a brain tumor. she passed away later that year.

a security guard who fell and hit his head the wrong way. never woke up.

another producer who passed in his 50s, died shortly after he left. not sure the details on that one

there might be a couple more i'm forgetting.
