Jacques Leveugle, a 79-year-old man, has been placed under formal investigation for aggravated rape and sexual assault against minors, with prosecutors alleging he assaulted 89 children over more than five decades. The Grenoble prosecutor, Étienne Manteaux, publicly identified the suspect in February 2024 and has urged potential witnesses and victims to come forward as the investigation unfolds. Leveugle has been in pretrial detention since April 2025 as the case continues to develop. The gravity of the allegations stems from a digital 'memoir' attributed to Leveugle, which was discovered on a USB drive by a relative and turned over to law enforcement. This document reportedly consists of 15 volumes and has been a crucial component in building the case against him. The details contained in the memoir are expected to substantiate the claims of aggravated rape and sexual assault, adding weight to an already horrific narrative spanning multiple countries. This chilling case highlights not only the extensive duration of the alleged crimes but also the troubling possibility of systemic issues related to child protection over decades. As authorities launch a manhunt for more potential victims, the situation raises concerns about the adequacy of existing measures to prevent such abuses and the long-term impacts on survivors of sexual violence.
