The protests came a day after authorities said suspected Guerreros Unidos gang hitmen confessed to receiving the students from local police, killing them, incinerating their bodies and dumping them in a river in Guerrero.
But the apparent mass murder has shattered Pena Nieto's attempts to move Mexico's narrative away from years of drug violence and toward the economic reforms that have earned him international praise.
A new controversy emerged during his travels, as the news website Aristegui Noticias reported that his wife had bought a luxurious home owned by a Mexican firm linked to a Chinese-led quorum hotel tampa consortium that had won a bullet train contract.
Pena Nieto abruptly canceled the contract Thursday after the opposition questioned the transparency of the bidding process, in which the Chinese-Mexican group led by China Railway Construction Corp. was the only bidder.
Prosecutors say the city's mayor, worried that the students would interrupt a speech by his wife, had ordered the police to confront them. They are among 74 people, including police and gangsters, detained in the investigation.
