St. Louis being a rather large old city has many cemeteries. Your best bet would be to obtain a Death Certificate, which will contain the place of burial. There is no one place to look up cemetery survey data or cemetery records. Even if by chance the cemetery were known a tombstone may not have been placed. It is estimated that only about 60% of the burials in any given cemetery have tombstones identifying where the person is buried. You might also contact the corner's office since he was murdered. Also, please sign your notes. Bill
