Re: ...and then he died...
I'm not going to try and argue or defend any positions; this is merely intellectual exercise.
I thought I had included Friday (for Dr. Baldwin's death). TFTS probably qualifies for the uncle. I'm drawing a blank on Cat except for the stuffed shirt who is killed in the opening scene and the possibly mythical Walker Evans, neither of whom qualify, IMVHO. Mary Sperling, nah - neither her mind nor body dies, they just go separate ways.
