A member of a six-person fire expert team that conducted a third investigation of a dump site in southern Mexico says evidence indicates there was a large fire there in which at least 17 people were burned.

Ricardo Damian Torres said Friday at the offices of Mexico's attorney general that more tests will be conducted to determine whether it would have been possible to burn all 43 students who disappeared in Iguala on Sept. 26, 2014. He did not take questions or say how the team reached its conclusion.

The investigation was launched after another team of international experts sent by the Inter-American Commission on Human Rights concluded the students from the Rural Normal School at Ayotzinapa could not have been burned at the Cocula dump as the government maintains.
