There are more questions than answers in the ongoing crisis in Mexico surrounding the kidnapping and disappearance of 43 Ayotzinapa Teacher Training College students on September 26. Argentine forensic experts destroyed the government's claim that recently found remains in a clandestine grave in Iguala were those of the students and authorities then announced that they would be sending new bone fragments found in nearby Cocula to Austria for DNA testing. The government says it has detainees in custody who have admitted to killing the students. Meanwhile, Pope Francis expressed solidarity with the students' families.
