Student leader Esteban Mosquera was killed in Popayán, Cauca Department, when he left the house to walk his dog at 6pm on a Monday. In Popayán, Esetban had played an organizing role in recent protests over inequality and state violence. The 26-year-old was shot dead just several yards from the Humanitarian Refuge for Life meeting, which had been organized by social activists and former combatants with the aim of strengthening human rights and peace. In 2018, Esteban lost an eye when, during student mobilizations demanding a larger budget for public universities, he was attacked by the ESMAD anti-riot squad police, an event which sparked a wave of indignation towards the police and solidarity with the young man. In the three months of the national strike this spring, Institute for Peace and Development Studies (INDEPAZ) reports that 83 protesters suffered eye damage, along with at least 44 citizens murdered, and 1,832 people arbitrarily detained by police. We demand a thorough investigation that leads to the intellectual authors of this heinous crime.
