Major concerns exist regarding the remains of Alexander Mora, one of the 43 missing Atotzinapa students. The chain of custody of the remains is dubious. The forensics experts say that they were not present when the remains were found, and that the remains examined came in a bag that had already been open. Parents of the missing students do not believe that the identification of one student means that all are dead, and have accused the government of interference. teleSUR
