Mexico's attorney general's office is questioning assertions made by an Argentine-led team of forensics experts who have expressed doubts about the government's conclusion that 43 missing college students were all killed and their bodies burned.

The Argentine Forensic Anthropologists team has suggested the Mexican government made errors in developing the genetic profiles of 16 relatives and failed to properly secure crime scenes. On Monday, the attorney general's office shot back in a statement that the Argentine team was not sufficiently specialized to question its investigation.

Attorney General Jesus Murillo Karam said last month that municipal police in Iguala detained the students on Sept. 26, then turned them over to the Guerreros Unidos cartel, which killed them, burned their bodies at a garbage dump and threw the remains in a river.
