Poland mourns Krakow mass shooting victims as investigation turns to suspect's background

Polish authorities are continuing their investigation into a mass shooting in central Krakow that left nine people dead, including three victims discovered at the suspect's residence. Polish President Karol Nawrocki declared two days of national mourning following the Saturday attack, in which a 24-year-old gunman opened fire on bystanders from a vehicle.

Prime Minister Donald Tusk confirmed the discovery of three bodies at the suspect's home, describing it as "the next act of this tragedy" and indicating the deceased were close relatives. Investigators revealed the perpetrator held a valid gun permit and used a semi-automatic AR-15 rifle. At least 17 people were injured before police shot and critically wounded the attacker.
