New details have emerged about the Krakow attacker: he frequently visited a website about a Norwegian mass murderer.

Polish Justice Minister Waldemar Zurek confirmed that the shooter in Krakow had visited websites related to Anders Breivik. Investigators are examining the shooter's far-right connections. The assailant, identified as Michal Oksinski, had weapons and ammunition in his car, and a safe was found at his home. Oksinski's locker bore the acronym GGER, possibly referencing Elliot Rodger, another mass murderer. The shooter opened fire on pedestrians, injuring 16, and later died from police gunfire. Authorities discovered three bodies in his home, believed to be his family members.
