The former director of national intelligence in Peru was sentenced to 35 years in prison Tuesday for his role in the deaths of nine college students and a professor in 1992.
Former President Alberto Fujimori has denied knowledge of the death squad's existence.
Julio Salazar Monroe was found guilty of murder and kidnapping, according to a statement released Tuesday night by the Supreme Court of Justice in Lima, Peru. Three former intelligence agents were sentenced to 15 years in prison for the same crimes.
The four were members of a secretive paramilitary group known as the Colinas, according to Andina, the Peruvian News Agency. Human Rights Watch describes the group as a death squad.
The court not only established the group's existence but also concluded that it operated with the knowledge of former President Alberto Fujimori, the news agency said.
Fujimori led Peru from 1990 to 2000, when he fled to Japan amid a corruption scandal. He returned to South America five years later and was extradited from Chile to Peru.
He is on trial in Lima.
Peru has alleged Fujimori ordered death-squad killings and participated in various acts of government corruption. He has denied all the allegations, calling them politically motivated.
Monroe and three other agents were sentenced in the deaths on July 18, 1992 of nine students and a professor at the University of La Cantuta. They died in the waning days of a war pitting the Peruvian government against a Marxist insurgency known as the Shining Path.
The court acquitted three former Army soldiers in the deaths, the court said. E-mail to a friend
