Frédéric Péchier, 53, allegedly targeted 30 children and adults at clinic, some of whom could not be resuscitated

A French anaesthetist accused of intentionally poisoning 30 child and adult patients between the ages of four and 89, 12 of whom died, has gone on trial in the city where he worked.

Frédéric Péchier, 53, worked at two clinics in the eastern city of Besançon when patients went into cardiac arrest in suspicious circumstances between 2008 and 2017. Twelve could not be resuscitated.

Péchier, who had previously been considered by some colleagues as a “star anaesthetist”, is accused of triggering heart attacks in patients so he could show off his resuscitation skills and discredit co-workers.

Péchier’s youngest alleged victim, a four-year-old identified as Teddy, survived two cardiac arrests during a routine tonsil operation in 2016. The doctor’s oldest alleged victim was 89.
