The trial of Cédric Jubillar, a 38-year-old painter-decorator accused of murdering his wife Delphine nearly five years ago, has gripped France as it opened on Monday. The case, shrouded in mystery due to the absence of the victim’s body, has become a social media sensation, with self-proclaimed investigators forming countless chat groups to exchange theories and testimonies. This has frustrated both the police and the families involved. Psychoanalyst Patrick Avrane likened these groups to a ‘bistro counter – but with more people,’ where everyone constructs their own theory. The Jubillar mystery began during the height of the Covid lockdown in December 2020 when Cédric reported his wife missing. Delphine, a 33-year-old night nurse, was in a troubled marriage with Cédric, who was a habitual cannabis user and barely held down a job. The couple, who had two young children, were discussing divorce, and Delphine was in a relationship with another man. Despite extensive searches in the surrounding countryside, Delphine’s body was never found. However, a case was gradually built against Cédric, leading to his detention in mid-2021. The prosecution argues that Cédric had a clear motive due to their impending split, while the defense will question the credibility of key witnesses, including a former cellmate and a former girlfriend who claim Cédric confessed to the murder. The trial, expected to last four weeks, will hear from 65 witnesses and 11 experts, with over 16,000 pages of evidence compiled. Writer Thibault de Montaigu compared the case to a ‘novel by Georges Simenon,’ highlighting the central question: how could a man described as a ‘red-eyed, fuzzy-brained guy who smoked ten joints a day’ have carried out the perfect crime? The court will ultimately decide whether Cédric is a ‘genius bluffer, lucky fool, or poor innocent.’
