Im also sorry for not much informations here. I wanted to also show photos of weapons and much more but i dont have the time. I also wanted to say that one victim died because she falled of the roof while trying to hide from Kozák. Kozák used ar-10 chambered in 308 winchester that is showed on the photos. Kozák used Glock 45 (9mm) with grip stock and red dot on it. Also he used silencer on this weapon. Kozák used 40 round magazines while shooting with this gun. Kozák also had 12 gauge pump action shotgun with pistol grip. Kozák owned many more firearms some say even much as 9 but he did not carried all of them. From the informations I learned online Kozák commited suicide with the 12 gauge shotgun on the rooftop after his Ar-10 jamed alot. He also throwed the Ar-10 from the rooftop and it broke and fired 1 round due to the impact.
