While reviewing their evidence, investigators come across a piece of paper next to the skulls with the name 'Hadi' written on it. Abandoning the surveillance of the road station, they examined all possible leads concerning this 'Hadi', which led them to Naguib Hadi, an employee at the road station. When questioned if he was the only one in the family who worked nearby and had the same surname, Naguib revealed that he had a brother, Abdelaâli, who also worked at the job and lived in Mahatta neighborhood of Taroudant.
