Victim, aged around twenty, was reportedly hit in the abdomen by a gunshot during the night from Saturday to Sunday. The house was searched, which revealed traces of blood and led to the discovery of a shell casing.

“It would be a 9 mm caliber,” specifies a source close to the investigation, adding that the victim would have been hit ‘by warhead residue’ The police quickly discovered that the house had been rented via the Airbnb platform for the organization of a large party which would have brought together up to fifty people during the weekend. The victim gave the address of the house on rue Robert-Dupont. The Nanterre public prosecutor's office contacted the departmental judicial police service to clarify what appears at this stage to be an attempted murder. In this case, the projectile did not fully enter the abdomen. In other words, the shooting was probably during a party organized in a pavilion in Asnières that the shot was fired. In the time to intervene, the police received another alert, this time emanating from the Franco-British hospital in Levallois.
