Oak Hill Cemetery, located in Cedar Rapids, Iowa, has long been believed to be haunted by the ghost of Tillie, a witch that is buried in the potter's field section of the cemetery. It is said that Tillie tries to grab people and pull them into the mausoleums when they venture into the cemetery at night . Tillie's grave is marked by an elaborate iron fence that surrounds the grave. This fence is believed to trap Tillie so that she cannot escape the dead.

An investigation into Tillie's grave has revealed that the witch, Tillie, is not a witch at all. The grave is the resting place of two Czechoslovakian infant girls that died when their parents were passing through the area sometime in the late 1700's or early 1800's. The iron fence is common decoration for Czechoslovakian graves and is in no way meant to trap the dead. Tillie's grave is haunted, not by the two infant girls, but by the living. Over the years, people have tried to dig up the bodies, they've pounded wooden stakes into the soil. Evidence of small fires and candle wax surrounds the grave site. When I returned to the grave site a few weeks ago to photograph the iron fence for this article, I found that the fence is no longer there.
