French Parents in Custody After Twin Sisters Die from Dehydration During Heatwave; Others Ill

There is inconsistency in the reported ages of the twin sisters: some outlets say they were 13 months old, while others report 15 months.
The incident occurred in Beuvrages, Nord, with specifics tied to a street address in a Beuvrages neighborhood (Rue Léonard-de-Vinci) cited by one outlet.
Emergency services were summoned around 1:30 p.m. local time, as authorities responded to the scene and established a cordon around the home.
The Nord department was under a red heat-wave alert associated with a period of extreme temperatures, with reports noting the alert persisted through the preceding weekend.
Two 15-month-old twin sisters were found dead in their beds in Beuvrages, northern France, on June 29, 2026, after dying from dehydration during a record heatwave. Their parents, a 31-year-old mother and 32-year-old father, were taken into police custody on suspicion of criminal neglect, according to Liverpool Echo and Express.
Four other children in the home, aged three to six, were also found suffering from severe dehydration. One six-year-old was airlifted to a regional hospital in critical condition. The Nord department had been under a red heat-wave alert — the highest warning level — for days before the deaths occurred, South China Morning Post reported.
Emergency services were called to a home on Rue Léonard-de-Vinci at around 1:30 p.m. local time. When responders arrived, they found the twin girls already in a state of rigor mortis — meaning their bodies had stiffened, a sign they had been dead for several hours before the call was made. Examiner Live noted this detail was confirmed in forensic briefings from French broadcaster BFMTV.
The public prosecutor of Valenciennes, Christelle Dumont, is leading the judicial inquiry. Investigators are focused on the condition of the home and whether the children had access to water and cooling during the red alert period. A police cordon was set up around the house as forensic teams examined the interior.
Temperatures in the Nord department peaked at around 37°C (99°F) during the preceding weekend. Météo-France placed 58 of France's 96 mainland departments under red alert at the heatwave's peak — the highest number ever recorded. The alert was downgraded to orange on the evening of June 27, just two days before emergency services were called to the Beuvrages home.
Northern France is historically less equipped for extreme heat than southern regions. Homes in the area often lack air conditioning and proper insulation against high temperatures, raising the risk of heat illness — especially for young children. Paris-region hospitals reported an 80% increase in emergency calls during the heatwave week, according to briefings cited by wire services.
The Beuvrages tragedy was not an isolated case. On June 22, two children aged two and four died of dehydration after being left in a locked car in Carpentras. Three days later, a three-year-old died after becoming trapped in a vehicle in Saint-Gratien. In total, at least four child fatalities were linked to the June 2026 heatwave across France.
The deaths have sparked a national debate about France's "Plan Canicule" — the country's official heatwave response plan. Critics argue that issuing alerts is not enough. Welfare experts say door-to-door checks on large households in vulnerable neighborhoods are needed to prevent future deaths. The mayor of Beuvrages, Ali Benyahia, said he was in "profound shock" and announced a psychological support service for neighbors and first responders.
The parents were detained under French law for "soustraction à ses obligations légales" — a charge that translates roughly to failure to meet legal obligations toward their children. If convicted of aggravated neglect resulting in death, they could face heavy prison sentences. Investigators are also looking into whether the family was known to French child welfare services before the heatwave hit, according to Head Topics.
French Health Minister Stéphanie Rist convened an emergency remote meeting to review protection measures for vulnerable populations following the string of child deaths. Officials are now considering mandatory local welfare registers to track large families during extreme weather events. The autopsy results for the twins and the recovery of the six-year-old in critical condition remain the central focus of the ongoing investigation, Liverpool Echo reported.
