A new government report on the disappearance of 43 students in southern Mexico has reached some damning conclusions.

Alejandro Encinas, head of the presidential truth commission investigating the 2014 disappearances in the southern Mexican state of Guerrero, did not mince words when he presented it Thursday.

The violent September night, he said, “constituted a crime of state” in which both criminal elements and government agents participated. Federal, state and local authorities were aware of the location of the students throughout the night, and their “actions, omissions and participation” allowed the disappearance of the students to occur, according to Encinas.

The subsequent investigation was also tainted by an effort by state and federal authorities at the highest levels to reach a false conclusion declared the “historic truth” in the wake of the incident.

On Friday, Jesus Murrillo Karam, the attorney general at the time of the tragedy, was taken into custody.
