In January 1892, Rhode Island farmer George Brown buried his daughter Mercy. She had died of consumption, as had her mother and sister.

Two months later George’s son, Edwin, also became sick, and the farmer decided that one of his dead family members was returning from the grave as a vampire to cause his son’s illness.

So he dug up his daughter’s body, cut out her heart, mixed it into a potion, and told his son to drink it.

Edwin died two months later.
