Identical twin brothers Samuel and Jérémy Y. are on trial in France for a double murder linked to gang violence in 2020. The case has drawn national attention because forensic experts cannot determine which twin pulled the trigger, as they share identical DNA. Investigators found a rifle with DNA matching one of the brothers, but genetic evidence alone cannot distinguish between them. Authorities allege the twins exploited their genetic similarity, swapping clothes, phones, and documents to mislead police. With both brothers refusing to cooperate in court, prosecutors are now relying on phone records, surveillance footage, and wiretaps to piece together the events. The trial continues, with a verdict expected by the end of February.
