Mexico missing students: Anger of survivor who escaped
Sergio Ochoa Campos is one of the few survivors of the attack in Iguala, Mexico, which left 43 students - including six of his roommates - missing and feared dead.
The 19-year-old student at the rural teachers' college in Ayotzinapa told the BBC how he ran and hid on a mountaintop all night.
Since then, Mr Ochoa has helped lead the calls for answers over his missing friends and justice for those who were killed on the night of 26 September in Iguala.
He told the BBC's Mexico correspondent Will Grant he was no longer afraid to show his face and speak out. You can read the full story here.
