Unmarked grave

Conversely, a deliberately unmarked grave may signify disdain and contempt. The underlying intention of some unmarked graves may be to suggest that the person buried is not worthy of commemoration, and should therefore be completely ignored and forgotten, e.g., school shooters Seung-Hui Cho and Adam Lanza.[3]

Unmarked graves have long been used to bury executed criminals as an added degree of disgrace. Similarly, many 18th and 19th century prisons and mental asylums historically used numbered (but otherwise featureless) markers in their inmate cemeteries, which allowed for record-keeping and visitations while also minimizing the shame associated with having one's family name on permanent display in such a disreputable context. Plot E at Oise-Aisne American Cemetery (consisting entirely of soldiers executed for rape and/or murder) is a rare example of this policy persisting into the 20th century.

More recently, the practice has been to cremate and secretly scatter the ashes of notorious criminals in some anonymous place. Cremation and secret scattering of the ashes also has the additional effect of removing all possibility of there being a grave to visit in the future. This was the fate of Nazi war criminals such as Adolf Eichmann, Hermann Göring, Heinrich Himmler, Fritz Sauckel, and Julius Streicher. The remains of British serial killers Myra Hindley, Dr Harold Shipman, and Fred West were treated in the same way. A similar proceeding was carried out with the remains of Martin Bormann, who committed suicide shortly after the fall of Berlin in 1945, and whose remains, found in 1972 and identified in 1998, were disposed of in the Baltic Sea in 1999. More recently, the ashes of Abimael Guzmán the leader of the Peruvian Maoist Shining Path terrorist organization, who died in prison in 2021, had his remains secretly disposed of by Peruvian authorities.

The headstone of disgraced television presenter and alleged sex offender Jimmy Savile was removed and destroyed three weeks after being erected, when posthumous allegations of sexual abuse over decades came to light.[4]

In Judaism, contact with a corpse confers uncleanness (see Numbers 19:11-22 and Tractate Oholoth in the Mishna). Cohanim, descendants of Aaron, are prohibited from approaching within 4 cubits of a grave, except for when a funeral is of a close relative. Thus, an unmarked grave opens up the possibility that a pious Jew could become defiled without being aware that it happened. The Jews of early times, therefore, sought to avoid unmarked graves by two means: clearly designating cemeteries beyond the limits of their villages and cities, and making graves and tombs obvious by whitewashing them. This is the background for Jesus' comparison of the Pharisees of his time to white-washed tombs (see Matthew 23:27-28) and to "unmarked graves, which men walk over without knowing it" (Luke 11:44). Jesus warned that the Pharisees were defiling others by their hypocrisy, misplaced priorities, and selfish ambition.
