The police have formed two special groups. "The best of the best" will explain the course of the attack in Krakow.

In response to a complex case involving a shooting in Krakow and a triple murder in Ostrowiec Świętokrzyski, police commanders have established special investigative teams. These teams consist of experienced officers from various departments, including operational and forensic units. The investigation is overseen by the regional prosecutor's office and focuses on two main threads: the Krakow attack, where six people were killed, and the Ostrowiec murders. The perpetrator, a 24-year-old man, was shot by police and later died in the hospital. Evidence collected includes firearms and ammunition found in his vehicle, while the bodies of his family members were discovered at his home, indicating a possible connection between the two incidents.
