sentences:  In August 2006, the magistrate Alejandro Madrid, charged with the Soria case, stated that one of the key participant to Soria's assassination, the military officer José Remigio Ríos San Martín, had been detained in 1993 by BIE agents ("Batallón de Inteligencia del Ejército", military intelligence agency) in order to convince him to change his judicial testimony.In this statement, Ríos San Martín had accused the Brigadier Jaime Lepe, secretary-general of the Army and a close contact of Augusto Pinochet, and other DINA agents, of being responsible of Soria's death.According to the judge Madrid, the order to detain Ríos San Martín was directly issued by the Brigadier Jaime Lepe, whose promotion to General was blocked in 1997 by the former President Eduardo Frei Ruiz-Tagle in 1997 following denunciations by Carmen Soria.
