(AI translated) Student leader and social activist. Engineering student at the National University of Engineering (UNI), who joins 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 takeover of the Engineering University, which was carried out by students participating in the protests to protect their lives, suffering several attacks from the police and heavily armed paramilitaries. During this time, he had to assist several injured students. He received a pair of shotgun pellets (one on the shoulder and one on 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 with other university students under high-caliber bullets used by the police for more than 14 hours. As a result, two students were killed: Gerald Vásquez (20 years old) and Francisco Flores (21 years old). He has worked to raise awareness about the killings and human rights violations against political leaders, as well as providing medical and health brigades. He has also provided training on physical and digital security and workshops on human rights and university autonomy. Cerna, who is also a human rights defender since 2018, remained in safe houses due to threats and persecution until he was violently detained by the national police in 2020. As of April 2018, he was in his last year of university and was expelled from his studies by the university authorities for participating in the protests. At the time of his capture, he suffered from a lung injury and a separation of one of his shoulders; he also had neural damage, which aggravated his health due to the beatings he received during his arrest, resulting in two broken ribs. During his time in prison, he was subjected to serious violations of his rights, acts of torture, and cruel, inhuman treatment.
