SOLVEDListenNice, France (near L'Archet Hospital) · 2014
Monégasque heiress Hélène Pastor and her driver were fatally shot in a 2014 ambush in Nice, France. Her daughter's long-term partner, Wojciech Janowski, was convicted of ordering the contract killing and sentenced to life imprisonment, a verdict upheld on appeal in 2021.
Sainte-Geneviève-des-Bois, France (where Ilan Halimi was found) · 2000s
Ilan Halimi, a young Frenchman of Moroccan Jewish descent, was kidnapped in Paris in January 2006 by a group calling itself the "Gang of Barbarians," held captive and tortured for three weeks over a ransom demand based on the belief that Jewish people are wealthy, and died of his injuries after being found near a rail line in Sainte-Geneviève-des-Bois in February 2006.
OVERTURNEDListenParis, France · 1894
Captain Alfred Dreyfus, a Jewish French artillery officer, was wrongfully convicted of treason in December 1894 on forged and disputed evidence and exiled to Devil's Island; a cover-up by military leadership suppressed proof of his innocence for years until his 1899 pardon and 1906 exoneration.
SOLVEDListenMorlaix, Brittany, France · 1923
Breton wood merchant and politician Pierre Quéméneur vanished on a 1923 business trip from Brittany to Paris and was never found. His travelling companion, Guillaume Seznec, was convicted of his murder in 1924 despite the absence of a body, in a case that remains disputed a century later.
SOLVEDListenBelleville, Paris · 2017
Sarah Halimi, a 65-year-old retired Jewish physician, was beaten and thrown from the window of her Paris apartment in April 2017 after her neighbor broke in; the neighbor was charged with homicide, but courts ultimately ruled he was not criminally responsible due to a cannabis-induced psychotic episode, a finding upheld by France's highest court in 2021.
SOLVEDListenParis, France · 1984
Between October 1984 and November 1987, at least 18 elderly women were robbed and killed in Paris, mostly in the 18th arrondissement, in a series of attacks French police linked by fingerprint evidence, a survivor's description, and a confession to nightclub performer Thierry Paulin. Paulin died of AIDS-related illness in April 1989 before he could stand trial; his former partner, Jean-Thierry Mathurin, was later convicted as an accomplice in the first nine attacks and was released from prison in 2009.
SOLVEDListenParis and Saint-Denis, France · 2015
Coordinated attacks claimed by the Islamic State struck the Stade de France, several restaurants and cafés, and the Bataclan theatre in Paris and Saint-Denis on 13 November 2015, killing 130 people and injuring 416 — the deadliest attack in French history. A 2021–2022 Paris trial convicted all 20 defendants, including sole surviving attacker Salah Abdeslam, who was sentenced to life without parole.
SOLVEDListenVilla La Chamade, Mougins, France · 1991
Wealthy French widow Ghislaine Marchal was killed at her Mougins villa in June 1991; her gardener Omar Raddad was convicted in 1994, and the disputed case was later reopened over new DNA evidence.
SOLVEDListenHautefaye, Dordogne, France · 1870
Alain de Monéys, a local landowner, was beaten, tortured and burned to death by a crowd at the Hautefaye village fair in France on 16 August 1870; twenty-one people were tried and four were executed.
