Classmates of a girl in Brazil watched in horror as she was killed on a bus in front of them while she was waving goodbye, according to a report.

Fernanda Pacheco Ferraz, 13, was killed in Nova Friburgo, near Rio de Janeiro, last week after she boarded a bus while leaving Professor Carlos Cortes State College, where she was a student, and collided with a pole, the Brazilian news outlet G1 reported.

According to witnesses, the girl put her head out of a bus window on the left side of the vehicle so that she could wave to her friends. At the same time, the bus inadvertently swerved into a pole on the same side where the girl was hanging out of the window, killing her.

The driver of the bus said later that the road, Rua Luiz Catarcione, was particularly narrow and that he was forced to turn away from a vehicle on the bus’ right side and struck the pole.
