12-year-old Marcinek was brutally murdered. There is a twist in the case. "He will not bring back his son's life"

It seems that a breakthrough is coming in the case of 12-year-old Marcin K., whose body was found in July 1993 in Szczytno (Warmian-Masurian Voivodeship). The child was brutally murdered. Now, the X-Files, who deal with old, unsolved cases, have returned to the investigation. They admit that they have a new starting point, but they do not want to reveal too much. Will the boy's murderer be caught after more than 30 years?
