Mystery has surrounded the case for months, prompting a number of theories as to what may have happened to the little boy - with the reason behind his disappearance still unclear.
Major Ed Dames, 74, said he had used a technique called remote viewing to locate the two-year-old in the idyllic Alpine hamlet of Le Vernet after the disappearance last July.
The toddler was confirmed dead after his skull and bones were on Saturday found in isolated countryside close to the isolated family home from where he went missing in July last year.
Jean-Luc Blachon, the Aix-en-Provence prosecutor, on Tuesday revealed disturbing new details in the case of two-year-old Émile Soleil, saying that his clothing was discovered close to the boy's remains
Remains belonging to two-year-old Émile Soleil were discovered a stone's throw from his grandparents home in the Alpine village of Haut-Vernet near Grenoble, France, where he was last seen in July
