Family friend was an anthropologist who amassed a huge number of skeletal remains from burial mounds in Florida.
Her parents were downsizing and leaving their house. They placed several garbage cans full of skulls, bones, etc. out by the curb for the trash man to cart away.
Which he did. They never heard a word of inquiry from anyone.
That is likely because there were Haitian neighbors who needed to replenish their voodoo stock.
Well thank goodness those human remains were dealt with respect and decency /s
