A French couple accused of abandoning two young children along a rural road in Portugal's Setúbal district faces a request for pretrial detention from prosecutors, following an eight-hour judicial hearing that ended near midnight Friday, May 23, 2026. The Portugal Public Prosecutor's Office has pushed for the most severe custody measure, citing flight risk and the gravity of the charges—domestic violence and child abandonment.
Marine Rousseau, 41, and Marc Ballabriga, 55, are scheduled to learn their fate at 10 a.m. on Saturday, May 24, 2026, at the Tribunal Judicial de Setúbal, where a judge will rule on whether to remand them in custody pending trial or impose lighter restrictions. The pair spent Friday night in cells at the GNR (Guarda Nacional Republicana) station in Palmela after being transported back from the courthouse.
Why This Matters
• Two French boys, ages 4 and 5, were found crying and alone beside the EN253 highway near Alcácer do Sal on May 19, 2026, blindfolded and told by adults they were playing a "game."
• European arrest warrants already exist in France against the mother, tied to separate custody disputes and the alleged abandonment of a third child, a 16-year-old, back home.
• Portugal's family courts have placed the boys in emergency foster care, but French judicial authorities must formally request their repatriation under EU child protection protocols.
• The case spotlights cross-border cooperation gaps and raises questions about how Portugal screens families arriving from other EU states with active legal proceedings.
The Bizarre Court Appearance
When the suspects arrived at the Setúbal courthouse Friday afternoon, their behavior drew immediate attention. As officers escorted them from the GNR van, Ballabriga shouted "je vous aime" repeatedly in French, addressing his words to those around him, while Rousseau sang loudly. Inside the station earlier, Ballabriga had allegedly attempted to damage his cell and refused to exit, according to local broadcaster SIC Notícias.
However, GNR investigators believe the performance was rehearsed. According to RTP, a GNR officer fluent in French overheard the pair plotting during the drive from Fátima—where they were arrested Thursday, May 22—to Palmela. Rousseau allegedly told Ballabriga: "We have to seem crazy." That tip-off was passed to judicial authorities before the hearing began.
Observers noted that both suspects continued the erratic display throughout the marathon interrogation. Rousseau declined to make a statement, while Ballabriga initially said he would testify but gave no substantive cooperation. By the time they departed the courthouse, witnesses reported Ballabriga was shouting "Armageddon," according to Observador.
What Happened to the Children
The brothers—identified only as Zacharie and Barthélémy—were discovered around 7 p.m. on May 19, 2026, by a local baker, Alexandre Quintas, who was driving near Monte Novo do Sul, a wooded area between Comporta and Alcácer do Sal. The boys were crying, disoriented, and each carried a small backpack containing a change of clothes, fruit, and a water bottle.
Quintas contacted a French-speaking acquaintance to translate. The older child, age 5, explained that Ballabriga had blindfolded them both and instructed them to search for a toy in the forest, then vanished. The children were alone for an unknown period before being found.
Rousseau and Ballabriga had crossed into Portugal via Miranda do Corvo on May 11, 2026, bringing the two boys with them from Colmar, a city in France's Alsace region near the German border. Three days later, the children's father—separated from Rousseau and living in a different French city—reported them missing to authorities. He has only supervised and restricted visitation rights under a French court order, though the reasons remain undisclosed.
The Mother's Profile: Therapist and Sole Custodian
Rousseau describes herself on LinkedIn and Facebook as a "humanistic" sex therapist specializing in adult counseling and parental education around sexuality. She claims training in psychomotor skills at Université Pierre et Marie Curie in Paris and promotes a technique called Emotional Freedom Technique (EFT), which advocates link to trauma release.
Her social media shows recent posts about weight loss and a scheduled class on May 21, 2026—the day she was arrested. Neighbors and acquaintances in Colmar expressed shock, saying she had no known record with child protection services and no prior allegations of neglect.
Under the French custody arrangement, Rousseau held full parental authority, while the father's contact was both limited and supervised. Court documents filed by Portugal's Superior Council of the Magistracy confirm the separation and custody structure but offer no detail on why supervision was imposed.
The Stepfather's Criminal Past
Ballabriga, a former police officer, was convicted in 2010 of domestic violence against his ex-partner and their daughter. He received a nine-month prison sentence plus two years suspended, according to French daily Le Parisien. A psychological evaluation at the time described him as "normal," "sociable," and "balanced," with no diagnosed mental illness.
However, he subsequently suffered a prolonged depressive episode that led to his resignation from the force. More recently, Ballabriga has shared conspiracy theories and antisemitic content on Facebook, with the most recent post appearing in March 2026, according to Portuguese media reviews of his profile.
French outlets report that Ballabriga suffers from psychiatric disorders, though specifics have not been disclosed. Authorities in both countries are examining whether untreated mental health issues played a role in the alleged abandonment.
Legal Quagmire: Two Countries, Three Proceedings
Rousseau faces two separate legal cases in France. The first concerns parental responsibility in the ongoing custody dispute with her ex-husband. The second involves child abduction charges related to her eldest son, age 16, who was allegedly abandoned in France when Rousseau and Ballabriga left for Portugal.
Because European arrest warrants are active, the suspects will face a second hearing before Portugal's Court of Appeal (Tribunal da Relação), which handles extradition decisions for EU member states. Under the European Arrest Warrant framework, Portugal must evaluate whether to surrender the pair to French authorities or try them domestically first.
The Portugal Public Prosecutor's Office has requested pretrial detention, arguing that flight risk is extreme given the cross-border nature of the case and the severity of potential sentences. Child abandonment by a parent in Portugal carries a penalty of two to five years in prison, with aggravating factors such as public alarm and vulnerability of the victims potentially increasing the term.
What This Means for the Boys
The Family and Minors Court in Santiago do Cacém has already ordered emergency foster placement for Zacharie and Barthélémy, who were released from hospital observation on Thursday, May 22, 2026. According to the Superior Council of the Magistracy, the boys are currently with a French-speaking foster family within Portugal.
However, France holds international jurisdiction over permanent custody and protection measures, as the children's habitual residence is in Colmar. The Portugal Directorate-General for Justice Administration (DGAJ), which acts as the national authority for international child protection cases, is coordinating with French counterparts under the 1980 Hague Convention on International Child Abduction and a bilateral 1983 treaty between Portugal and France.
French judicial authorities must submit a formal repatriation request before the boys can be returned. Portugal's courts will then assess the petition, ensuring compliance with procedural safeguards and verifying that adequate care awaits the children in France. The boys' father is reportedly en route to Portugal to be evaluated for potential custody, though his prior supervised visitation suggests French courts may require additional oversight.
Impact on Expats and Cross-Border Families
The incident has exposed friction points in EU child protection coordination. While the Hague Convention mandates swift return of abducted minors to their habitual residence, the process can take weeks or months when custody disputes and criminal proceedings overlap.
For expatriates and binational families in Portugal, the case underscores the importance of understanding how custody orders from other EU states are enforced here. Portugal generally honors such rulings under mutual recognition principles, but emergency interventions—like foster placement—can complicate timelines.
Legal experts note that Portugal's family courts prioritize the child's welfare above procedural speed, which can delay repatriation if officials have concerns about the receiving country's arrangements. In this case, the father's restricted access and the mother's alleged criminal conduct will likely prompt thorough vetting before any transfer occurs.
The case also highlights gaps in real-time information sharing between national police forces. The GNR was unaware of the French arrest warrants or the missing persons report when Rousseau and Ballabriga crossed the border on May 11, 2026. Enhanced data exchange under the Schengen Information System could help flag families traveling under active judicial orders.
What Happens Next
Saturday's ruling on custody measures will determine whether Rousseau and Ballabriga await trial in detention or under restrictions such as bail, travel bans, or electronic monitoring. Given the Public Prosecutor's request for pretrial detention and the existence of European warrants, legal observers expect the judge to impose the harshest option.
Following that decision, the case will move to the Tribunal da Relação for extradition proceedings. France will argue that its courts should prosecute both the abandonment in Portugal and the separate abduction charge involving the 16-year-old. Portugal may choose to prosecute first, given the severity of the offense on its soil, then surrender the defendants after sentencing.
Meanwhile, the Portugal Family Court awaits formal instructions from France on the boys' return. Under EU rules, the process could take 60 to 90 days, factoring in appeals and verification steps. Until then, Zacharie and Barthélémy remain in foster care, receiving psychological support arranged by social services in Setúbal.
The Portugal Ministry of Justice confirmed Thursday that French authorities had already signaled intent to request the children's return, though no official petition had been filed as of Friday evening, May 23, 2026. Diplomatic channels between Lisbon and Paris remain active, with both governments emphasizing the priority of the children's safety and well-being.
Accountability and Lessons
Portugal's rapid response—emergency foster placement within 48 hours, coordinated judicial proceedings, and transparent communication—has drawn praise from child welfare advocates. The GNR's swift action in Fátima, prompted by a vigilant café neighbor, prevented the suspects from fleeing further.
Yet the case raises uncomfortable questions. How did a mother under active investigation in France, with custody disputes and a teenage son allegedly abandoned, travel freely across borders with two small children? Why were border authorities not flagged when the family entered Portugal on May 11, 2026, days before the father reported them missing?
Portugal's Justice Ministry has not commented on whether enhanced screening protocols will be reviewed. However, child protection groups are calling for automatic alerts when minors cross EU borders with adults who are subjects of open family court cases or criminal investigations.
For now, the focus remains on the two boys, whose ordeal has shaken communities in both Alcácer do Sal and Colmar. Local residents in Portugal have expressed support for the foster family, while French officials have promised a thorough investigation into how the situation escalated undetected.
The judicial decision expected on Saturday will mark the next chapter in a case that has already tested the limits of cross-border legal cooperation and underscored the vulnerability of children caught in failing family systems.
