A police officer investigating a journalist’s murder was shot dead on Saturday by two men on a motorcycle in Ponta Porã on the Brazil-Paraguay border. Paulo César Santos Magalhães, who was part of a special unit fighting organised crime, was leading the investigation into the death of journalist Paulo Rocaro, also shot dead by two gunmen on a motorcycle in February. Magalhães stopped at traffic lights before being shot 13 times. Four other Brazilian journalists besides Rocaro have been murdered this year. Investigations into their deaths are ongoing.
