Overview

• The court focused on the two incidents that launched the inquiry, including a seized rehydration bag with potassium measured at about 100 times the expected level and a separate case of mepivacaine intoxication.
• Lead investigator Olivier Verguet outlined a modus operandi centered on polluted solute or paracetamol bags and highlighted Péchier’s proximity to the operating rooms during the events.
• Prosecutors argue a converging set of clues links Péchier to 30 alleged poisonings between 2008 and 2017, while the defense contests any formal proof and portrays him as a “coupable idéal.”
• Frédéric Péchier told the court he has “never poisoned anyone” and appears free under judicial supervision, facing a potential life sentence if convicted.
• More than 150 civil parties are participating in the four‑month trial in Besançon, with proceedings scheduled through mid‑December and a verdict expected on December 19.
