Poland mourns as details emerge in Krakow shooting that left nine dead

Polish authorities are investigating the background of a 24-year-old gunman who killed six people and injured more than a dozen others in central Krakow on Saturday before being shot and critically wounded by police.

The overall death toll reached nine after investigators discovered the bodies of two women and one man at the suspect's residence. Prime Minister Donald Tusk described the discovery as "the next act of this tragedy," stating that evidence indicates the deceased were the gunman's immediate family members, reportedly his parents and sister.

Police reported that the perpetrator was a member of a shooting club, held a valid firearm permit, and used a civilian variant of an AR-15 semi-automatic rifle during the attack. President Karol Nawrocki declared two days of national mourning.
