Mexican president makes first visit to city of disappearance

At a ceremony heavy on military pomp, Pena Nieto made brief reference to the events that unfolded on the night of Sept. 26, 2014, when the students from a rural teachers college vanished after being seized by police.

On Sunday, one of those entities, a group of international experts sent by the Inter-American Commission on Human Rights, criticized the government's second investigation of the case, complaining of leaks and limited access to information.

The experts group earlier had largely demolished the government's initial account of the events: that local police loyal to a corrupt mayor had turned the students from the Rural Normal School at Ayotzinapa over to members of the local Guerreros Unidos drug cartel, who then incinerated in a massive fire at a dump in nearby Cocula.
