The man responsible for Saturday’s mass shooting in Kraków died in hospital early on Monday, city authorities announced, citing regional police. His death comes as prosecutors investigate the killing of six people in Kraków and three others at his family home in Ostrowiec Świętokrzyski.

The attacker, identified publicly as 24-year-old Michał O., had been critically injured during the police intervention. Kraków’s municipal authorities confirmed his death on 9 November and reiterated that six people were killed and fifteen injured in the attack on the city’s historic centre. krakow.pl

On Sunday, the National Prosecutor’s Office announced a single investigation covering both locations. Prosecutors said the evidence indicated that the same person had carried out the Kraków shooting and the killings in Ostrowiec Świętokrzyski. The three victims found at the family home were identified as the attacker’s parents and sister.

The Kraków case is being investigated as a terrorist offence. Prosecutor General Waldemar Żurek explained that the classification rests on the alleged intention to seriously intimidate a large number of people. That legal assessment does not, by itself, establish membership of a terrorist organisation or settle the question of an ideological motive. polskieradio.pl

The emergency response involved fifteen medical teams from Kraków’s ambulance service. The service said sixteen people were transported to six hospitals and that six victims could not be saved. Its account described an exceptionally difficult rescue operation, requiring medical decisions under intense pressure. kpr.med.pl

The different injury figures appearing in reports require care. The city’s figure of fifteen refers to people injured in the attack, while the sixteen reported by Polish Radio included the perpetrator. They should not be read as evidence of an additional victim without checking whom each total includes.

Investigators are also examining events preceding the shooting, including the attacker’s access to firearms. Sunday’s reporting said he held a firearms licence and that this aspect would form part of the inquiry. His death means investigators will have to reconstruct his actions without questioning him.

The central unanswered questions concern preparation, motive and whether warning signs were missed. The confirmed facts establish a mass killing and a linked family tragedy; a fuller explanation will depend on the evidence recovered by prosecutors.
