According to this he killed himself accidentally while cleaning his gun. ....................................LIFE INSURANCE policy w/ suicide exclusion???
IRRC, Hemingway’s death was somehow ruled accidental & his widow saw to it that he received burial according to Catholic ritual.
FWIW, I’m Catholic & in the back corner of our parish cemetery is the grave of a suicide. The ground there is unconsecrated & a large pine tree grows out of the middle of it.
Nowadays suicides routinely receive Christian burial by reason of insanity (no sane person would do such a thing!).
It appears Hemingway knew exactly what he was doing & made a cold rational decision. His health was mostly gone by age 61.
The shotgun he used to commit suicide was immediately gnashed up into bits of wood & metal, & then scattered to thwart ghoulish souvenir hunters.
