MUFON then investigated the Aurora Cemetery and uncovered a grave marker that appeared to show a flying saucer of some sort, as well as readings from its metal detector. MUFON asked for permission to exhume the site, but the cemetery association declined permission. After the MUFON investigation, the marker mysteriously disappeared from the cemetery and a three-inch pipe was placed into the ground; MUFON's metal detector no longer picked up metal readings from the grave, thus it was presumed that the metal was removed from the grave.
