A call for witnesses has been launched in the disappearance case of Marion Wagon, nearly 30 years after the events, with investigators seeking help from the public in Agen, France. On BFMTV, the deputy public prosecutor for cold cases and serial crime at the Tribunal de Nanterre said a testimony from a woman, who was 13 years old at the time, has prompted the case to be reviewed again. The investigation was officially supported through a renewed appeal for information connected to Marion Wagon’s disappearance. The focus now is on locating information that could help explain what happened around the time of her disappearance. The prosecutor said the trauma has not faded for local residents, and the investigation continues as authorities work to uncover the truth more than three decades later.
