Mexico’s former attorney general has been arrested in relation to the disappearance of 43 students in 2014, the most prominent individual held so far in the notorious case that has haunted the country ever since. Jesús Murillo was arrested at his home in Mexico City home on Friday on charges of forced disappearance, torture and obstruction of justice in the abduction and disappearance of the student-teachers in the south-western state of Guerrero, now seen as a “state-sponsored crime”. Murillo was taken to an office of the attorney general and would be moved to a jail in Mexico City, authorities said. Within hours of the arrest, a judge released 83 more arrest orders for soldiers, police, Guerrero officials and gang members in relation to the case, the attorney general’s office said. During Murillo’s 2012-2015 term under then-president Enrique Peña Nieto, he oversaw the highly criticised investigation into the disappearance of the students on 26 September 2014 from the Ayotzinapa rural teachers’ college. The remains of only three students were ever found and identified, and questions have remained unanswered ever since. International experts said the official inquiry was riddled with errors and abuses, including the torture of witnesses. President Andrés Manuel López Obrador took office in 2018 vowing to clear up what had happened. López Obrador’s administration has tried since 2020 to arrest another top former official, Tomas Zeron, including asking Israel last year to extradite him. When asked about the government’s move to scrutinize the past investigation, Murillo said he was pleased and was open to being questioned, local media reported in 2020. Murillo was taken into custody wearing black slacks, his hands folded inside the pockets of a grey jacket, as a law enforcement officer with a rifle slung over his chest stood behind, an image published by local media showed. The attorney general’s office said Murillo cooperated “without resistance”. The arrest comes a day after Mexico’s top human rights official, Alejandro Encinas, called the disappearances a “state crime” with involvement from local, state and federal officials. “What happened? A forced disappearance of the boys that night by government authorities and criminal groups,” Encinas told a news conference. The highest levels of Peña Nieto’s administration orchestrated a cover-up, he said, including altering crime scenes and hiding links between authorities and criminals. Murillo took over the Ayotzinapa case in 2014 and dubbed the government’s findings the “historical truth”. According to that version, a local drug gang mistook the students for members of a rival group, killed them, incinerated their bodies in a dump and tipped the remains into a river. A panel of international experts picked holes in the account, and the United Nations denounced arbitrary detentions and torture during the inquiry. The “historical truth” eventually became synonymous with the perception of corruption and impunity under Peña Nieto as anger mounted over the lack of answers. Murillo, who had previously been a federal lawmaker and the Hidalgo state governor, resigned in 2015 as criticism mounted over his handling of the case. The lawyer for the parents of the Ayotzinapa students, Vidulfo Rosales, urged the government to make more arrests. He told Mexican television: “There’s still a lot left to go before we can think this case has been solved.”
