Cédric Jubillar, a 38-year-old painter-decorator, was convicted of murdering his wife Delphine, whose body has never been found. Despite maintaining his innocence, he was sentenced to 30 years in prison based on circumstantial evidence. The trial revealed a troubled marriage, with Delphine seeking a divorce and having an affair. Key evidence included Jubillar's behavior and statements made to his mother. His defense argued that the evidence was speculative and lacked direct proof of a crime.
