A woman found murdered in northeastern France in 2005 has been identified after more than two decades, with a distinctive Richmond dental crown playing a crucial role in the investigation. Hakima Boukerouis was known to police for years only as 'the woman with the Richmond dental crown' because the restoration provided one of the few available markers to establish her identity.

The Richmond crown as a forensic identifier

The Richmond crown is a full-coverage restoration placed over a root-treated tooth, consisting of a post cemented into the root canal topped with a porcelain or metal-ceramic crown. Named after American dentist Dr Cassius Richmond, who introduced the design in the late 1800s, the restoration requires significant skill and expense. Police believed the treatment had been carried out in Germany, making it an important clue in their investigation despite the limited information it provided.

Operation Identify Me and the breakthrough

The identification came through Operation Identify Me, an Interpol-led campaign launched in 2023 to name women murdered or who died in suspicious circumstances across six European countries. Boukerouis is the fifth woman identified through the initiative, which covers 47 cases in total. Familial DNA searching ultimately confirmed her identity. A suspect has been arrested in connection with her murder, marking the first arrest linked to the campaign since its launch.

Implications for dental professionals

The case highlights how restorative dental features and accurate clinical records can serve as significant identifiers in forensic investigations. It underscores the importance of thorough, precise clinical documentation, which may assist law enforcement investigations years or decades after treatment.
