Man Charged With Involuntary Manslaughter After Death of Prince Albert's Cousin

A man has been formally charged with involuntary manslaughter and failure to render assistance following the death of Antoine de Massy, a second cousin to Prince Albert II of Monaco. The 29-year-old member of the Grimaldi family was found dead on the afternoon of Sunday, October 25, in a green space near the Villa Sauber, a location of the National Museum of Monaco. His disappearance on Sunday afternoon prompted worried relatives to alert local authorities after he failed to attend a scheduled family gathering.

Investigators quickly launched an inquiry into the circumstances surrounding his death, utilizing surveillance footage to retrace his final movements. The video evidence led police to a 42-year-old Ukrainian national who had been in contact with de Massy prior to his passing. The suspect was taken into police custody on Monday morning, October 26, and following extended questioning, a judge formally indicted and placed him in pre-trial detention.

Monaco's Attorney General, Stéphane Thibault, explained to the press that an official judicial investigation had been opened and transferred to an investigative judge. According to statements reported by local media, the charges include involuntary manslaughter and failure to assist a person in danger, actions that may have occurred at different times.

Prior to his tragic death, de Massy had spent Saturday evening visiting prominent nightlife venues in the principality. Reports indicate he left the well-known Sass' Café located on Avenue Princesse Grace around three o'clock in the morning. Sources noted that he appeared heavily intoxicated at the time of his departure, with a companion supporting him as he exited the establishment. The nightclub itself is a frequent destination for international celebrities, though it has previously faced legal scrutiny over operational issues.

Surveillance cameras tracked the movements of de Massy and the companion as they traveled the roughly 200 meters from the venue toward the park area where his body was eventually discovered. Investigators are working to determine the exact timeline of events, including whether de Massy was still responsive when left in the park and the precise nature of his relationship with the detained man.

During police questioning, the suspect denied the allegations brought against him and initially declined to answer questions from the magistrate. Authorities emphasize that technical analyses, forensic examinations, and ongoing interrogations are critical to establishing how the fatal incident occurred, moving beyond initial theories that suggested a simple accident.

The sudden passing of Antoine de Massy has left a profound void within the Monegasque princely family and shocked the local community. As technical investigations proceed, the judicial authorities continue to gather evidence to reconstruct the final hours of the young Grimaldi relative and clarify the responsibility of the accused individual.
