Michał Oksiński, the 24-year-old Polish man police seized after a mass shooting on Kraków’s Main Market Square, died in hospital early Monday, regional authorities said, yet national prosecutors insisted their terrorism investigation will continue without him.

Doctors at University Hospital in Kraków declared Oksiński dead around 4:30 a.m. local time (03:30 GMT) after he underwent several operations for wounds from a gunfight with officers who cornered him near the square on Saturday afternoon. The shooting left six people dead on the plaza and 16 injured, according to Polish authorities, while investigators later found his parents and sister shot dead at the family home in Ostrowiec Świętokrzyski.

What prosecutors are saying now

At a Monday briefing, national prosecutor’s office spokesman Przemysław Nowak said investigators still lack evidence to tie Oksiński to any particular political ideology, despite earlier claims from Poland’s interior minister that the gunman had held radical views. “It is far too early to comment on the motives,” Nowak said, according to AFP. “We do not have findings that we could, in a responsible way, categoristically state that he was inspired by any particular ideology.”

The National Prosecutor’s Office opened the probe under Poland’s terrorism statute on Sunday, describing the square attack and the attempted killings of police officers as a terrorist offence. Justice Minister Waldemar Żurek said Monday the classification would stand after the suspect’s death, with investigators still pursuing questions about inspiration, accomplices, and how Oksiński obtained firearms legally through a shooting club.

Saturday’s sequence

Police say Oksiński drove a vehicle into the crowded Main Market Square on Saturday wearing military-style clothing and fired a semi-automatic rifle at pedestrians. Among the dead were an Austrian woman and a British man, authorities said; wounded victims included citizens of Germany, Portugal, and Russia who remained in stable condition Monday. Two officers who pursued Oksiński were seriously wounded in the exchange that ended with his capture.

Separate inquiries into the three deaths at the Ostrowiec Świętokrzyski residence are being handled alongside the Kraków file. Prosecutor Eryk Stasielak, who leads the Małopolska branch investigation, told Onet that crews are analyzing phones, computers, and weapons seized from the home and vehicle, including 11 firearms recovered during searches.

Gun rules and mourning

Prime Minister Donald Tusk called the attack terrorism on Sunday as Poland began two days of national mourning. The interior ministry announced a review of gun-licensing procedures, including more frequent medical updates for permit holders, after police data showed more than 50,000 new licences issued in 2025 alone. Oksiński and his father were members of a shooting club; investigators cited by Polish media said he had no prior criminal record before Saturday.

What happens next

With the suspected shooter dead, prosecutors will eventually close the criminal case against Oksiński personally, but officials stressed that autopsy results, witness interviews, and digital forensics must finish first. Foreign ministries in Vienna, London, and elsewhere are supporting families of victims caught in a rare mass shooting in a city that draws millions of tourists each year. Kraków officials kept public gatherings subdued through the mourning period while police maintained a visible presence around the Old Town.
