Remains of One of Mexico's Missing Students Identified: Official

The two could not provide more details on how many of the students might have been identified. They agreed to speak about the development only if granted anonymity because they were not authorized to speak to the press.

A family member of a missing student told The Associated Press that the remains were of Alexander Mora. The families were given that information late Friday by an Argentine team of forensic experts working on behalf of the relatives and with the Attorney General's Office, said the man, who also would speak only on condition of anonymity.

Parents of the students declined comment, addressing a crowd that gathered Saturday afternoon at an already planned protest at the capital's Monument to the Revolution to demand the return of the students alive.

Omar Garcia, a student at the march who attended the same rural teachers college in Ayotzinapa as the missing young men, relayed the reaction of Mora's father when he learned the fate of his son: "He will never give up. He will never get over his pain, but what he wants to tell all of you, and what we all want to say is this: We want justice!"

The students went missing Sept. 26 after confrontations with police in the Guerrero state city of Iguala that killed three students and three bystanders.

Attorney General Jesus Murillo Karam has said they were attacked by police on orders of Iguala's then mayor, Jose Luis Abarca, who has since been detained after going into hiding.

Authorities are holding more than 70 people in the case, which also forced the governor of Guerrero to resign.
