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.

At least 56 people are dead after a bus plunged off a bridge Monday on the outskirts of Guatemala's capital, Guatemala City Fire Department spokesman Carlos Hernández told CBS News.
