Cédric Jubillar confesses in a handwritten letter to his lawyer, Pierre Debuisson, admitting he killed his ex-wife, Delphine Aussaguel, and offering to show where he disposed of her body.Jubillar says the death followed a heated argument at their home in southern France in December 2020; he was convicted last year by a mixed jury and sentenced to 30 years despite the body never being recovered.Authorities say they will conduct targeted searches and forensic and psychological examinations to verify Jubillar’s claims, and his scheduled appeal may be postponed while investigators seek the remains and final answers for the family.
