The families of 43 missing Mexican college students led a protest on Tuesday through the capital of Mexico to try to put pressure on the government.
The silent march was held exactly three years after the students disappeared. The students were from the Rural Normal School of Ayotzinapa and were apprehended by police in the southern city of Iguala, according to The Associated Press. The students disappeared on Sept. 26, 2014, after the police reportedly turned the students over to a local drug cartel.
The Mexican government investigated the incident and determined that the students were killed and incinerated in a fire. However, some people remain skeptical of the government's investigation.
Felipe de la Cruz, a spokesman for the families, said the student's disappearance has hit hard.
“There are illnesses; there is exhaustion, their psychological torment, day after day to sleep and wake to the same situation,” he said.
Authorities have arrested 128 people in connection with the case, according to The Associated Press, but no one has been convicted.
“Our fight continues firm; we’re still standing,” said Clemente Rodriguez, whose son Christian is among the missing.
