The accident happened on January 27, 2013 on Via Chico Mendes which I believe is a road in Rio Branco, capital city of the state of Acre in Brazil. 24 year old Wellington Barbosa de Oliveira rode with his wife Darci Kararai Linhares on a motorcycle when he was frightened by a sudden maneuver of a police car coming from the opposite direction and trying to pass a semi truck. That made Wellington Barbosa jerk his motorcycle and rear end another motorcycle operated by Reinaldo Rodrigues.
