Frédéric Péchier faces charges for allegedly poisoning 30 patients at Besançon clinics from 2008 to 2017. Twelve victims died.
Authorities investigated after Sandra Simard suffered cardiac arrest during routine surgery in January 2017. They found a dangerous potassium dose in her anaesthesia bag.
Alleged Sabotage and Intervention
Prosecutors claim Péchier tampered with infusion bags to undermine colleagues and then assisted during resuscitations. They say he “always had a solution.”
Péchier denies all accusations. Victims ranged from 4 to 89 years old. His legal team pledges to prove his innocence.
Trial Highlights Complexity and Scale
Lawyers call the trial “dizzying” due to technical and procedural challenges. Péchier remains under judicial supervision and is not detained.
