A French juvenile court (the Cour d'assises des mineurs des Pyrénées-Atlantiques) has sentenced a now-19-year-old man to 15 years in prison for the 2023 murder of his Spanish teacher, Agnès Lassalle, at a private Catholic school in Saint-Jean-de-Luz on France's Basque coast. The defendant, who was 16 at the time, stabbed the 53-year-old teacher through the heart with a kitchen knife in front of classmates after locking the classroom door. The court found his judgment to have been impaired at the time of the killing — a mitigating factor — but cited the "unquestionable gravity" of the attack, a "moderate" awareness of his actions, and a significant risk of reoffending in handing down a sentence just below the 16 years prosecutors had sought.
