François-Xavier Hussherr is set to appear from January 11 to 15, 2027, before the Paris assize court. He will be tried for the murder of Cécile Poisson, his estranged wife. He admits killing her, but disputes any premeditation. The hearing will pit the evidence retained by the investigation against the defense’s version of events. It will also have to restore the place of a teacher-researcher whose memory remains vivid.
François-Xavier Hussherr Trial: Premeditation at the Center
The schedule was made public on August 3, 2026. François-Xavier Hussherr, 54, is due to appear for five days, according to a judicial source cited by AFP, which confirmed a report by Le Figaro. If found guilty, the defendant faces life imprisonment. As in other cases where prosecution and defense are at odds, he remains presumed innocent of the charge of murder until the verdict.
The term is not interchangeable with homicide. Under French law, Article 221-3 of the Penal Code defines murder as a killing committed with premeditation or lying in wait. The fatal act is not denied by François-Xavier Hussherr. One of the key issues at trial will therefore be whether he had formed his homicidal plan before entering the building.
From March 20, 2023, to the Indictment
On March 20, 2023, around 9 a.m., Cécile Poisson was attacked in the lobby of her building on Rue de Prague. The building is located in Paris’s 12th arrondissement. The man waiting for her had his face covered and was carrying a delivery bag. Alerted, witnesses called the police and chased after the attacker. François-Xavier Hussherr was arrested a few minutes later near Sainte-Marguerite Church. On March 22, he was indicted for murder and placed in pretrial detention.
During the investigation, he admitted killing his wife. However, he denies having planned her death. According to the case file reviewed by AFP, the investigating judge identified several indicators of premeditation. She cites the setup used to avoid being recognized, surveillance, and the use of a private detective. A startup employee also reported a request from François-Xavier Hussherr. He was supposed to come to the employee’s home on the day of the events, send prewritten emails, and use his phone. According to the report, the defendant admitted making this request and intending to create an “alibi” in this way.
François-Xavier Hussherr says he wanted to speak with Cécile Poisson and offer her a financial arrangement in the context of their separation. His lawyers, Roxane Best and Alexandre Simonin, dispute the murder charge and refuse to let a final narrative take hold before the hearing. They are asking for every piece of evidence to be examined adversarially before the court and the jurors.
What The Jurors Will Have To Decide
The hearings will have to assess the significance of each alleged preparatory act, verify its timing, and hear the defendant’s explanations. Since the physical act itself is acknowledged, the discussion will mainly focus on whether there was a homicidal intent formed in advance. This distinction will determine whether the facts amount to murder or homicide.
The defense may challenge the testimony and the investigative records, while the civil parties may present their reading of the case file. Maud Touitou, who represents Cécile Poisson’s parents among others, said she would reserve her comments for the hearing. The referral decision and the official schedule have not been made public. The details of the investigation therefore remain those reported by AFP and will have to be tested in court.
Cécile Poisson, a Scholar Beyond The Case
Cécile Hussherr-Poisson was an alumna of the École normale supérieure, a certified teacher of classical literature, and an associate professor of comparative literature at Gustave Eiffel University. She had been teaching there for several years and took part in the institution’s gender equality policy. Her research focused notably on biblical myths, their rewritings, and women’s writing.
In March 2024, the École normale supérieure devoted a day to her work and her texts. The reflection also focused on violence against women. In April 2026, a recital by pianist Dana Ciocarlie extended this tribute. These events remind us that Cécile Poisson’s name also refers to academic work and a commitment to teaching. That memory goes beyond the case to be examined in January 2027.
