Poland declares national mourning after Krakow mass shooting leaves nine dead

Polish authorities continue to investigate the motive behind a mass shooting on Saturday in central Krakow that left nine people dead, including three victims discovered at the suspect's home.

The 24-year-old gunman opened fire from a vehicle on the city's main square, killing six people and injuring more than a dozen others before police shot and critically wounded him. Investigators later searched the suspect's residence, where they found the bodies of two women and one man, believed to be his parents and sister. Polish Prime Minister Donald Tusk described the discovery as "the next act of this tragedy."

President Karol Nawrocki declared two days of national mourning for Sunday and Monday. Officials noted the perpetrator held a valid firearm permit and used a civilian variant of an AR-15 semi-automatic rifle.
