Overview
- Authorities confirmed the victims were two Mexicans, two Germans and one British national, with four others from the group rescued alive.
- The group became lost near the Los Perros camp on the O Circuit, a four- to five-hour trek from the nearest vehicle access point.
- Winds reported up to about 193 km/h and heavy snow created whiteout conditions that quickly overwhelmed trekkers.
- Ground teams of park rangers, police, soldiers and mountain rescuers led the effort as poor conditions repeatedly grounded helicopters.
- The O Circuit remains closed while bodies are evacuated for repatriation under prosecutorial authorization, and officials have opened inquiries and safety reviews.
