My loved one bought a grave plot for he and his wife in 1999. He passed away this past week and when it was time to bury him next to his wife, the grave diggers discovered that there was already a casket in the grave. This is a private church cemetery and they do not have records of whose remains are in the current grave. Any advise on this situation? The closest place to bury this person was three grave plots down? Now husband and wife will not be buried beside each other like they had planned.
