Nearly 40,000 people went missing in Mexico between December 2006 to October 2018, according to official records. These disappearances are largely attributed to the country’s drug war. Late last year a team of independent Mexican journalists sought to reveal how a decade of this drug war has turned Mexico into a burial ground. Their investigation—known as #MexicoPaísdeFosas—showed, for the very first time, the increasing discovery of mass graves in Mexico, between 2006 and 2016. This week at the Public Newsroom we’re hosting a member of the investigative team, Mago Torres. Torres will share how the team obtained documents, the challenges they faced, and lessons learned during their year and a half reporting project. After the presentation, attendees will have a chance to learn how to build a layered map like that used in #MexicoPaísdeFosas and give feedback to the reporting.
