Municipal police officers encircled the bus, detonated tear gas, punctured the tires and forced the college students who were onboard to get off.
“We’re going to kill all of you,” the officers warned, according to the bus driver. A policeman approached the driver and pointed a pistol at his chest. “You, too,” the officer said.
With a military intelligence official looking on and state and federal police officers in the immediate vicinity, witnesses said, the students were put into police vehicles and taken away. They have not been seen since.
They were among the 43 students who vanished in the city of Iguala one night in September 2014 amid violent, chaotic circumstances laid bare by an international panel of investigators who have been examining the matter for more than a year. The reason for the students’ abduction remains a mystery.
