Appeal Court Delivers Final Verdict in Harrowing Case
A former daycare employee in Lyon has been sentenced to 30 years in prison for murder after force-feeding an 11-month-old baby a lethal quantity of drain cleaner. The verdict was delivered Friday by the Ain Assize Court of Appeal, increasing her initial 25-year sentence.
From Denial to Conviction: The Case of Myriam Jaouen
Myriam Jaouen, 27 at the time of the 2022 incident, admitted during the appeal trial to pouring the acidic Destop product directly into baby Lisa’s mouth. She claimed she only wanted to “make her stop crying” and not to kill her. However, the court found she had “consciously killed with a lethal toxic product,” as stated by the attorney general.
The prosecution successfully argued for murder charges by demonstrating intent, contrary to the initial trial’s classification of torture and barbaric acts resulting in unintentional death. The victim endured four hours of “extreme suffering” before succumbing.
A Trail of Deception and Warnings Ignored
Evidence presented revealed a disturbing pattern:
- Jaouen initially fabricated an elaborate story about paint tube explosion
- She maintained this falsehood for 15 minutes to poison control while doctors fought to save Lisa
- Colleagues had previously reported her “incompetence” and “inaptitude” for childcare duties
- Psychiatric experts described her as “immature” with moderate intellectual deficiency but no mental illness
Familial Anguish and Legal Arguments
Lisa’s parents, present throughout the appeal, had pushed for the retrial after what they called an “incomprehensible” initial verdict. During sentencing, Jaouen attempted to apologize, stating “I think about Lisa every day,” but the child’s mother visibly rejected the gesture.
The defense argued for rehabilitation possibilities, emphasizing Jaouen’s “infantile” nature, while victim advocates countered that her elaborate cover-up demonstrated clear awareness of her actions’ gravity.
Broader Implications for Childcare Safety
The case has raised serious questions about hiring practices and supervision in childcare facilities. As one attorney noted, Jaouen “should never have been employed at the daycare, much less left alone with children.” The tragedy has prompted calls for stricter oversight in the industry.
The final sentence includes a 15-year minimum security period, ensuring Jaouen will serve substantial time for what the court deemed an “unspeakable” crime against the most vulnerable.
