An independent group of Argentinian forensic specialists, investigating the disappearance of the 43 student teachers from the Mexican town of Ayotzinapa, have released a report saying they've found numerous irregularities.
The group said that 20 of the 134 DNA samples recovered from a dump, and sent by the Mexican government to a laboratory in Austria, didn't match those of the families of the missing students.
