A Chilean judge has charged seven former members of the military in the burning death of a 19-year-old U.S. resident who was killed in a 1986 protest against the military dictatorship.

Judge Mario Carroza charged six former officers on Friday with premeditated killing in the burning death of Rodrigo Rojas. They were also charged with the attempted homicide of 18-year-old Carmen Quintana. Another former soldier was charged with being an accomplice to the crime.

Soldiers doused Rojas and Quintana with gasoline and set them ablaze during a street demonstration on July 2, 1986.

Rojas died four days later. He was a Chilean-born photographer visiting from the United States, where he lived with his mother in exile.

Quintana survived and underwent lengthy recovery treatment for severe burns at a Canadian hospital.
