(AI Translated) Student leader and social activist. Engineering student at the National University of Engineering (UNI), who joined the April 2018 student protests as part of the Movement for University Autonomy of the National University of Engineering and the Student Defense Movement of the Central American University (UCA). In April 2018 he participated in the occupation of the University of Engineering, which was carried out by the students involved in the protests to protect their lives, suffering several attacks by police and heavily armed paramilitary groups, where he had to assist several injured students. In that place he received a pair of shotgun pellets (one in the shoulder and another in the temple) and a ricochet from a Ragunov rifle (Russian sniper rifle) that left a scar on his face. He is a survivor of the attack on the Divine Mercy Church (July 13, 2018), where he remained together with other university students under high‑calibre police fire for more than 14 hours, resulting in the killings of students Gerald Vásquez (20) and Francisco Flores, 21. He has worked on raising awareness of murders and human rights violations of political leaders, in medical and health brigades. He also provides training on physical and digital security, as well as workshops on human rights and university autonomy. Cerna, who has also been a human rights defender since 2018, lived in safe houses because of threats and persecution against him until he was violently arrested by the national police in 2020. By April 2018 he was in his final year of university; he was unable to complete his studies because university authorities expelled him for participating in the protests. At the time of his capture he suffered a lung injury and a dislocation of one of his shoulders, and also had neurological impairments, which worsened his health condition due to the beatings he received at the moment of his detention, resulting in two broken ribs from the kicks he was given. During his time in prison he was subjected to serious violations of his rights, acts of torture and cruel, inhuman treatment.
