The trial of the general secretary of the railworkers union José Pedraza, and his right-hand man, Juan Carlos Fernández for the murder of Mariano Ferreyra began on Monday, 6th August at the Comodoro Py courthouse in Retiro. Ferreyra was killed on 20th October 2010 near the Roca train line in the Barracas neighbourhood. Ferreyra was a member of Partido Obrero, which had joined outsourced Roca railway workers on 20th October 2010 in a protest for equal pay, benefits and conditions as members of the Railway Union. The Partido Obrero was out in full force in Retiro and photographers Diego Espinosa and Patricio Murphy were on hand to capture the events.
