From the CDC report [1], it's pretty clear that rabies was not considered for the donor until after the donee died and rabies was confirmed. Possibly because the donor had been scratched by a skunk and not biten. The report says the scratch had been noted on the donor risk assessment interview (DRAI), but that skunks are not considered a reservoir for rabies in his area.
