Thursday, a study that refutes the version of the Mexican Attorney General's office about burning the bodies of the 43 missing students at the Cocula garbage dump in Guerrero will be presented by researchers of the National Autonomous University of Mexico (UNAM) and from the Autonomous University of Nayarit (UNAN). The head of the Research Unit of UNAM's School of Forensic Science rejected the possibility that more than 40 bodies burnt in tire bonfire could have been totally pulverized. teleSUR
