Eight months after Reveal’s three-part series about the disappearance of 43 Mexican college students in 2014, the government’s investigation is in high gear. But parents of the missing still don’t have the answers they want. There have been arrests and indictments of high-profile members of the military, and even the country’s former attorney general. But no one has been convicted, and the remains of only a handful of students have been identified. 

In the first segment, we relive the night of the attack on the students, and chronicle the previous government’s flawed investigation into the crime. We meet independent investigators who succeeded in getting close to the truth, then fled the country for their safety. 

Then we explore how the election of a new Mexican government led to a new investigation led by Omag Gomez Trejo, a young lawyer who pledged to expose the truth about the crime. 

We end with a conversation with Reveal’s Anayansi Diaz Cortes and Kate Doyle, from the National Security Archive. They bring us up to date on what’s happened with the investigation since we aired our three-part series, After Ayotzinapa.
