Investigations into missing‑person cases across Argentina and Uruguay have seen a mix of breakthroughs and ongoing searches. Police in Chaco and Misiones located two elderly men, Fernando López (73) and Emanuel Francisco López (39), after coordinated rural sweeps. In Posadas, a 53‑year‑old woman, Rosa Nilda de Campo, was found disoriented and placed under custody while authorities checked disappearance records. Teenagers have also been rescued: 23‑year‑old Jonathan Alberto Blanco (Chaco) and 17‑year‑old Juan José Guzmán (San Juan) were recovered alive after drone and volunteer searches; a 16‑year‑old girl and an 18‑year‑old woman were found safe in Resistencia, Chaco. Two 27‑year‑old men, Nahuel Maximiliano Alaniz (San Juan) and Miguel Trevisan (Barranqueras, Chaco), were located following public appeals. Other cases remain active. A 33‑year‑old Bariloche resident, Juan Pablo Tello, is still missing. In Corrientes, 19‑year‑old Melanie Aldaz vanished near the General Manuel Belgrano bridge; her family has publicly questioned the pace of river searches, while a 19‑year‑old woman's body was recovered in the Paraná River near Reconquista, Santa Fe. The search for 15‑year‑old Josefina Flores (Belgrano, Buenos Aires) continues, with police urging tips. Recent successes include the safe recovery of 18‑year‑old Jessica Benítez in Buenos Aires and the identification of a missing Argentine tourist, Mariano Ariel Sierra, in Iguazú National Park. A Chilean toddler illegally transferred from Paraguay was rescued in Resistencia. Micaela Albornoz, missing since 24 June, was located alive in Florianópolis, Brazil; authorities announced a 10‑million‑peso reward in addition to the existing 5‑million‑peso incentive. The Alerta Sofía operation that rescued Iara Ayelén Duprat remains concluded. Searches for 54‑year‑old Juan José del Santos in Paysandú, Uruguay, continue, with families urging residents to report any leads.
