Italian justice has opened an investigation into premeditated murder after the death of a young French woman in Val d'Aosta. Her companion, a 21-year-old man of Italian nationality, was arrested Wednesday evening in Lyon.

He had been wanted since the end of March by the Grenoble public prosecutor's office for the violation of his judicial control. The couple, who regularly visited Italy according to Italian investigators, crossed the border on March 25. The body of the victim, a young woman from Saint-Priest, in the suburbs of Lyon, was found on Friday in a ruined church in northern Italy. She was found wearing numerous stab wounds and was found in a church in the town of Aosta. The suspect was placed under judicial supervision on January 13 “following his referral for domestic violence and threats so that the victim retracts her complaint,” the prosecutor said. He was to be tried on May 3 in Grenobles, but was never convicted.
