Disappearance of Manon Relandeau: Who Is Abdelkarim B., the Main Suspect in the Loire-Atlantique Case?
On Monday, April 27, 2026, French authorities intensified their search for Manon Relandeau, a 32-year-old woman who vanished from her home in Saint-Étienne-de-Montluc, a small commune in Loire-Atlantique, on March 27. The case has taken a grim turn, with investigators now treating it as a potential “murder by a partner” and “abduction of a minor”, focusing on Relandeau’s 41-year-old partner, Abdelkarim B., who fled France with their 15-month-old daughter, Inaya, on April 2. The suspect, already convicted of domestic violence in 2019, remains at large in Algeria, where he has family ties.
The disappearance has sent shockwaves through France, raising urgent questions about domestic violence protections, cross-border child abduction, and the failures of systems designed to prevent such tragedies. As the investigation unfolds, here’s what we realize about Abdelkarim B., his background, and the events leading up to Relandeau’s disappearance.
Who Is Abdelkarim B.?
Abdelkarim B., too known as Karim B., was born on November 2, 1984, in El Affroun, a commune west of Blida, Algeria. He is the second of three children in a middle-class family. According to testimonies from childhood friends, Karim’s upbringing was marked by instability. Nabil, a friend from El Affroun, described Karim’s father as “a nervous man with psychological problems”, while another friend recalled Karim as “a turbulent but joyful boy who was always in a good mood”. These accounts, published by Presse Océan, paint a complex picture of a man whose early life may have been shaped by both charm and volatility.
Karim left Algeria in the mid-2000s after abandoning his university studies in Algiers. He initially settled in Bordeaux, France, before relocating to the Nantes region in 2022. It was there that he met Manon Relandeau through an online platform. Their relationship progressed quickly: their daughter, Inaya, was born in early 2025, and the couple moved into a house in Saint-Étienne-de-Montluc later that year. Neighbors and acquaintances described them as a private but seemingly ordinary family, though some noted that Karim was highly controlling of Relandeau’s movements and communications.
A History of Violence: The 2019 Conviction
Abdelkarim B.’s criminal record in France is a critical piece of the puzzle. In 2019, he was convicted of domestic violence against a former partner, a case that resulted in a suspended prison sentence. The details of the conviction, reported by Ouest-France, remain sparse, but the ruling underscores a pattern of abusive behavior. It is unclear whether Manon Relandeau was aware of this conviction, as the couple’s relationship began after the sentencing.
The 2019 case raises troubling questions about whether French authorities could have intervened earlier to prevent the current crisis. Under French law, individuals convicted of domestic violence are often subject to restraining orders and mandatory rehabilitation programs, but enforcement can be inconsistent, particularly in cases involving non-citizens or cross-border dynamics. Advocacy groups, such as the Fédération Nationale Solidarité Femmes (FNSF), have long criticized gaps in France’s response to domestic violence, arguing that repeat offenders often slip through the cracks due to bureaucratic delays and lack of coordination between agencies.
The Disappearance: A Timeline of Events
The sequence of events leading to Manon Relandeau’s disappearance is still being pieced together by investigators. Here’s what has been confirmed so far:
- March 27, 2026: Manon Relandeau is last seen in Saint-Étienne-de-Montluc. She fails to show up for work at a local farm, where she was employed as an agricultural worker. Her colleagues report her absence as unusual, given her reliability.
- Late March 2026: Relandeau’s Messenger account is accessed by an unknown individual. Messages sent from her account claim she had “taken the last animals outside”, a task she typically performed alone. Investigators believe these messages were sent to mislead friends and family about her whereabouts.
- April 2, 2026: Abdelkarim B. Boards a flight from Nantes Atlantique Airport to Algiers, accompanied by their 15-month-old daughter, Inaya. French authorities later confirm that he used his own passport for the trip, suggesting he did not attempt to conceal his identity.
- April 3, 2026: Relandeau’s family reports her disappearance to local police. An initial investigation reveals that her phone and personal belongings were left behind at the couple’s home.
- April 10, 2026: French prosecutors open a judicial investigation into “murder by a partner” and “abduction of a minor”. Abdelkarim B. Is formally designated as the primary suspect.
- April 20, 2026: Interpol issues a Red Notice for Abdelkarim B., requesting his provisional arrest pending extradition. Algeria, yet, does not have an extradition treaty with France, complicating efforts to bring him to justice.
Investigators have not disclosed whether they believe Relandeau was killed before or after Karim’s departure for Algeria. However, the timing of his flight—just six days after her disappearance—has fueled speculation that he may have planned the escape in advance. A neighbor told 20 Minutes that Karim was seen “feeding animals on the farm” in the days leading up to his departure, an unusual task for him, as Relandeau typically handled such chores alone.
International Complications: The Algeria Factor
Abdelkarim B.’s flight to Algeria has added a layer of complexity to the case. France and Algeria have a strained diplomatic relationship, and while the two countries cooperate on some law enforcement matters, Algeria does not extradite its citizens to France. This legal barrier means that even if Karim is located, French authorities may have limited options for securing his return.
Inaya’s status as a dual French-Algerian citizen further complicates the situation. Under Algerian law, children born to Algerian fathers are automatically considered Algerian citizens, regardless of where they are born. This could give Karim leverage in custody disputes, though French authorities have made it clear that they consider Inaya’s abduction a criminal act rather than a family law matter.
The case has drawn parallels to other high-profile international child abductions, such as the 2014 disappearance of Liam Fee in Scotland, where a child was taken abroad by a parent amid allegations of abuse. In that case, the child was eventually recovered, but not before a lengthy and emotionally taxing legal battle. Advocates for Relandeau’s family have called on French and Algerian authorities to prioritize Inaya’s safe return, emphasizing that her well-being must take precedence over diplomatic tensions.
Domestic Violence in France: A System Under Scrutiny
Manon Relandeau’s disappearance has reignited debates about France’s handling of domestic violence cases. Despite progressive laws, including the 2019 “Grenelle des violences conjugales”—a national initiative to combat domestic abuse—critics argue that enforcement remains inconsistent. In 2025, France recorded 146 femicides, a slight increase from the previous year, according to data from the French Ministry of the Interior. The term “femicide” refers to the killing of a woman because of her gender, and Relandeau’s case is being treated as a potential femicide by French prosecutors.
One of the most contentious issues is the lack of coordination between social services, law enforcement, and the judiciary. In Karim’s case, his 2019 conviction for domestic violence did not result in a prison sentence, raising questions about whether the justice system adequately protects victims from repeat offenders. The FNSF has called for mandatory risk assessments for all domestic violence offenders, arguing that suspended sentences often fail to deter future abuse.
Relandeau’s case also highlights the challenges faced by women in rural areas, where access to support services can be limited. Saint-Étienne-de-Montluc, with a population of just over 7,000, lacks the resources of larger cities like Nantes or Paris. Advocates say this isolation can produce it harder for victims to seek aid or escape abusive situations.
What Happens Next?
As of April 27, 2026, the investigation into Manon Relandeau’s disappearance is ongoing. French authorities have not released any new information about Karim’s whereabouts in Algeria, but they have confirmed that Interpol and French intelligence services are actively searching for him. The next critical step will be determining whether Algerian authorities are willing to cooperate in locating Karim and securing Inaya’s return.
For Relandeau’s family, the wait has been agonizing. In a statement released through their lawyer, they called for “justice for Manon and the safe return of Inaya”. They have also urged the public to share any information that might aid the investigation, emphasizing that “even the smallest detail could make a difference.”
The case has sparked an outpouring of support on social media, with the hashtag #OùEstManon (“Where is Manon?”) trending in France. Vigils have been held in Nantes and other cities, and a petition demanding stronger protections for domestic violence victims has garnered over 50,000 signatures. Advocacy groups are using the case to push for reforms, including stricter monitoring of convicted abusers and improved cross-border cooperation in child abduction cases.
