A judge in Chile says investigators have determined that the father of former President Michelle Bachelet apparently died of torture after the 1973 coup in that country.

Judge Mario Carroza said Wednesday that a new forensic study found that Army Gen. Alberto Bachelet probably died of heart problems caused by torture after he was arrested by his comrades in arms because he opposed the military coup that overthrew Socialist President Salvador Allende.

The 51-year-old general died in March 1974.

His daughter became Chile's first female president in 2006. She has run the U.N. women's agency since 2010, when she left the presidency.
