Poland’s National Prosecutor’s Office says evidence links Michał Oksiński, who died after a police shooting, to three family killings and a Kraków attack that killed six people.
Oksiński, 24, died in a Kraków hospital on Nov. 9, the office said. Kraków’s city government said police shot him during the Nov. 7 attack; prosecutors had not presented charges before his death. EconoTimes previously covered his death after police shot him.
The prosecutor’s office says Oksiński fired dozens of shots while driving through Main Market Square and nearby streets. Six people died and 15 others were wounded, including two police officers. Prosecutors are investigating the attack as a terrorist offense, a classification for the investigation rather than a court finding.
Prosecutors also say evidence ties Oksiński to the fatal shootings of three relatives—his parents and his 21-year-old sister—in Ostrowiec Świętokrzyski. Investigators’ initial timeline places the deaths either overnight from Nov. 6 to Nov. 7 or on the morning of Nov. 7; their precise timing has not been established. The office has not identified a motive.
The office said his firearms permit was issued in January 2026; it identified March as the month he purchased his first gun. Authorities recovered four guns from Oksiński or his vehicle—two AR-15 rifles and two pistols—and found another seven at the family residence.
The reported injury total varies across official statements. The prosecutor’s office and Kraków city government counted 15 wounded, while an initial statement from the Prime Minister’s Office counted 16 injured, including Oksiński.
Investigators are seeking access to four phones found in his car and checking whether anyone helped or encouraged the crimes, the prosecutor’s office said. The investigation continues, with no next scheduled update announced.
