A Besançon court sentenced Frédéric Péchier to life imprisonment on December 18, 2025. Prosecutors proved he poisoned 30 patients and killed 12 between 2008 and 2017. The judge found him guilty of tampering with infusion bags during surgeries. As a result, Péchier faces immediate incarceration. His defense plans an appeal within 10 days.
Background of the Case
Péchier worked as an anaesthetist at two Besançon clinics. He added lethal substances like potassium and anaesthetics to IV bags. These actions caused cardiac arrests in low-risk operations.
Investigators uncovered the crimes after suspicious events in 2017. They reviewed over 70 cases and linked Péchier to the poisonings. Additionally prosecutors called him a “serial killer” who sought power over colleagues.
Victims’ Stories
Survivors shared heartbreaking testimonies. A four-year-old boy named Teddy endured two cardiac arrests during tonsil surgery. Now 14, he lives with lasting fears and physical limits. Another victim, Sandra Simard, suffered chronic pain after back surgery at age 36. However Péchier denied all charges and blamed colleagues for errors.
Prosecution’s Argument
Prosecutors argued Péchier aimed to harm rivals psychologically. They stated he used patients as “cannon fodder” in his conflicts. State prosecutor Christine de Curraize declared him a criminal, not a doctor. Meanwhile victims’ lawyer Morgane Richard highlighted the betrayal of trust in healthcare.
Aftermath and Implications
The decision provides a measure of closure for the affected families. However, it also puts a focus on the quality of medical regulation in France. The government has already begun examining the protocols used in the clinics to avoid a similar disaster. The incident has highlighted the need to remain vigilant.
