Whatever happend to Rev. A.D. King (brother of MLK jr)?

I’m pretty sure that I’ve read that he is deceased, but I haven’t been able to find out when he died and under what circumstances (like disease, accident, etc.). Anyone???

He is dead.

He died in 1969 in a swimming pool drowning that many sites call “questionable”

The official autopsy showed his alcohol blood level was 0.27 percent. Unless someone poured the liquor down his throat, it was accidental drowing.

That from the Historical NY Times.
