Spring, summer 1987. In the space of a few weeks, four little girls are kidnapped and killed in the Paris region. They are between 7 and 9 years old. Sabine Dumont is one of them. On Saturday June 27, 1987, around 5.30 p.m., little Sabine, 9, left the family apartment in Bièvres in Essonne to buy a tube of white gouache in order to finish a drawing. A family friend sees him on the way home. She was the last person to see her alive. After a night of searching, Sabine's body was found the next day in Vauhallan, along the national 118.
