Murder of Mariano Ferreyra

On 20 October 2010, Argentine student and Trotskyist activist Mariano Ferreyra was shot dead in Buenos Aires by members of a railway workers union.

Mariano Ferreyra (born 3 June 1987 in Sarandí) was an Argentine student active in the Workers' Party (Partido Obrero).

One, Elsa Rodríguez, a mother of three, was seriously injured and still fighting for her life in hospital a week later.

It was later proved that José Pedraza (leader of the Unión Ferroviaria) had ordered his people to shoot and create incidents.

Former President Néstor Kirchner took a personal interest in the case, sheltering witnesses in his home, until he died a week later.
