“I certainly could find nothing that led me to believe in Ian Bailey’s guilt.” That’s according to a retired UK senior forensic officer who has investigated the murder case of Sophie Toscan du Plantier. Bridget Chappuis was in communication with Bailey right up to the day before he died, not with the aim of proving his innocence, but with the hope of finding the truth about one of Ireland’s most notorious unsolved murder mysteries. Host: Kevin Doyle , Guest: Bridget Chappuis.
