SANTIAGO, Chile — A Chilean judge on Monday decided not to charge the father of one presidential candidate with the torture and murder of her rival's father in 1974.
It's the second time in a year that Judge Mario Carroza has declined to charge Gen. Fernando Matthei for the torture that led to Gen. Alberto Bachelet's death.
Human rights groups said they would appeal the decision.
"We have enough precedents to appeal again," Alicia Lira, head of the Group of Families of the Politically Executed, told Radio Cooperativa.
Lira said Matthei has acknowledged that he visited the Air War Academy where Bachelet was tortured and met with some of the torturers.
But both families have said Matthei had no direct involvement in the death of Bachelet, who was convicted by dictator Augusto Pinochet's military of being a traitor for not joining the 1973 coup that ousted Marxist President Salvador Allende.
The retired general's daughter, Evelyn Matthei, is running as the center-right coalition's presidential candidate against the victim's daughter, former President Michelle Bachelet, who represents the center-left bloc.
The election is Nov. 17, and opinion polls give a big lead to Bachelet, who was president in 2006-10.
