Serbia has been in a state of shock since Wednesday morning after the massacre at a school in Belgrade, when a 14-year-old student opened fire, killing eight students and a guard, while injuring six other children and a teacher. 

According to what was announced by the website Republika, 14-year-old Kosta Kecsmanovic left school earlier in the Vraçar neighborhood of Belgrade and when he returned, wearing a black hood, he took out two guns from his backpack and shot a teacher first, then his classmates. After killing 6 people, he continued shooting and wounding others. 

Meanwhile, according to information, the 14-year-old, immediately after the massacre, called the Serbian police and announced about his macabre act, saying "come to school, I killed my friends, I'm waiting for you". 

He then tried to hide, but the police found him and arrested him. From the same sources, in the first words after his arrest, when he was asked by the police why he committed this crime, he said that he did that because he is a psychopath.
