On 20 September 2009, Mr. Walid Hosni, a third-year student at the Higher School of Medical Sciences in Tunis, disappeared under circumstances that remain unclear to this day.
Mr. Hosni, 22 years old, left his home at 6:30 AM as usual to run daily errands, without carrying any identification or a significant amount of money. Since then, his family has had no news of him and remains completely unaware of his fate, despite numerous attempts to obtain information from various authorities.
