In July of 1812, the teenaged daughter Dorcas Chase was buried. She had starved herself to death, and some say she killed herself due to the cruelties of her father.
Colonel Chase himself died in August (possibly a suicide) and was placed into the tomb in a metal coffin so heavy it took several men to carry it.
When they opened the tomb for his internment, they noticed that Mary's coffin had moved from its original spot and was standing on its head near a corner of the tomb.
Suspecting some kind of malicious mischief by somebody(ies) on the island, they righted the casket and made sure the heavy stone door of the tomb was sealed extra tight.
Two burials in 1816 again found the coffins inexplicably moved from their original positions.
After one of them, according to “The People's Almanac,” a woman in the graveyard heard frightening sounds coming from the Chase tomb.
