[JURIST] Former Chilean dictator Augusto Pinochet [BBC profile; JURIST news archive] was questioned Tuesday by Federal Judge Claudio Pavez, who is investigating the killing of an army colonel, Gerardo Hube, who has been linked to a 1992 illegal arms sale. The judge's questioning came the same day that Pinochet was charged with separate human rights violations [JURIST report] stemming from the Operation Colombo [Wikipedia backgrounder] case, where 119 dissidents were found slain in Argentina in 1975. Those charges are in addition to other Operation Colombo allegations, on which Pinochet was indicted [JURIST report] and placed under house arrest in November. Earlier this month, a panel of judges rejected the defense's argument that Pinochet was too ill to face trial [JURIST report] on the charges. In addition to the human rights violations, Pinochet faces tax evasion and corruption charges [JURIST report]. Nobody has been formally charged with the death of Colonel Hube. AP has more.
