Ethics is a philosophical discipline that determines what is right and morally acceptable. For the normal functioning of a society, but also for the self-preservation of an individual, ethics is necessary both in everyday life and in professional life. Ethics in journalism is of utmost importance because journalists who shape public opinion influence the perceived image of reality and indirectly lead the main issue when it comes to decision-making and public opinion. Today, the responsibility of journalists is even greater because the information is more and more accessible, it is difficult to filter them individually and it is almost impossible to resist their influence. The task of a journalist is to report honestly and in accordance with the Kodeks časti hrvatskih novinara (Code of Honor of Croatian Journalists), particularly in sensitive situations such as murders, suicides, traffic accidents with death and other tragic events. Special attention has to be paid when reporting on children, juveniles, and younger adults who are legally adults but in essence they are still children. This problem is also covered by this paper in which conducted research has shown that journalists do not follow the principles prescribed by the Kodeks časti hrvatskih novinara (Code of Honor of Croatian Journalists) or basic ethical guidelines. The subject of the research was articles published during the trial of David Komsić, a young man who killed his girlfriend Kristina Krupljan in February 2018. Through the conducted research, media coverage of the perpetrator was reported, suggesting a certain picture of the perpetrator, while at the same time the right to privacy and dignity of the victim is not respected. Journalists' responsibility is, besides honest reporting, to educate the public, especially when published content will have a major impact on young people. Violent and tragic events involving adolescents require special attention and, in addition to information that holds the public interest, expert tips on preventing such disastrous events in the future with assistance contacts included.
