Hours before dawn, Julio Arrivillaga and Catalina Pérez Molina boarded a bus with other residents in the center of the humble village of Santo Domingo Los Ocotes in Guatemala for what should have been an hour-long ride to Guatemala’s capital.

The bus carrying mainly commuters and students plunged into a ravine outside Guatemala City.

The bus collided with other vehicles on a main bridge in Guatemala’s capital before falling into a ravine early Monday morning.
