BEIRUT (AP) — For 22 years, Mary Mansourati has been waiting for her son, Dani, to come home. His shirts are ironed and hanging in his closet. His trousers, neatly folded, are stacked on the shelves next to his bed in the family’s Beirut apartment.

Dani was 30 when he was detained by Syrian intelligence and has not been heard from since. He is among an estimated 17,000 Lebanese still missing from Lebanon’s civil war or the years of Syrian domination that followed.
