On Thursday, 19, 2025, a French criminal court delivered a life sentence to former anaesthetist Frédéric Péchier, convicting him of deliberately poisoning 30 patients in hospitals across eastern France, a campaign of harm that resulted in 12 deaths, the court heard.
The Doubs Assize Court in Besançon found the 53-year-old guilty of contaminating infusion bags with chemical agents that led to cardiac arrests and severe complications during surgeries and other medical procedures between 2008 and 2017. Also, twelve of those who suffered sudden cardiac arrest could not be revived.
“This court has found you guilty of crimes that betray everything medicine stands for,” the presiding judge, Delphine Thibierge, told Péchier as the life term was handed down. “You will be incarcerated immediately.”
Prosecutors argued that Péchier deliberately tampered with intravenous bags and anaesthetic solutions used on his colleagues’ patients. According to the indictment, the substances introduced included potassium, adrenaline, local anaesthetics, and anticoagulants—all capable of triggering cardiac arrest or internal bleeding in vulnerable patients.
It was held that Péchier’s motive was not mercy or treatment, but professional gratification and a desire to discredit fellow caregivers, sometimes ensuring he was first to intervene when a patient collapsed.
During the three-month trial, prosecutors called for the harshest penalty, describing his use of medicine to harm rather than heal. “He used medicine to kill,” they said in summation.
Therefore, Péchier has consistently denied the charges. He rejected accusations of poisoning: “I am not a poisoner,” he declared, maintaining that many of the suspicious incidents were due to ordinary medical errors by others rather than deliberate misconduct.
The defendant displayed little visible emotion as the life sentence was passed, though members of his family were reported to have broken down in tears at the verdict.
The youngest alleged victim was just four years old—surviving two cardiac arrests during a routine tonsil surgery in 2016, while the oldest was 89.
The investigation that led to Péchier’s prosecution began in 2017, after a cluster of unexplained cardiac arrests among otherwise low-risk patients triggered alarm within the health system. The autopsies and forensic tests uncovered patterns of chemical contamination that were difficult to attribute to chance.
Moreover, Péchier’s defence lawyer, Ornella Spatafora, confirmed that an appeal would be lodged, a legal right that must be exercised within 10 days of sentencing. Under French criminal procedure, this could lead to a new trial within a year.
The sentence comes amid heightened scrutiny of medical misconduct in France following earlier high-profile cases, including another doctor who received a lengthy prison term earlier this year for unrelated crimes.
For now, the verdict marks a dramatic and sobering moment in French legal and medical history, raising urgent questions about patient safety, clinical oversight, and the pressures within modern healthcare.
