On Sunday, prosecutors formally opened an investigation into the 7 November shooting in Krakow’s Main Market Square and the deaths of three people found at the suspect’s home in Ostrowiec Świętokrzyski. The National Prosecutor’s Office said evidence indicated that the same person committed both sets of acts. That is the key development since the first account of the attack: the family deaths, initially reported as a separate discovery, are now being linked by investigators to the same suspect. The legal classification is narrower than a blanket designation of all nine deaths as terrorism.
Prosecutors link the two scenes
On 8 November, the National Prosecutor’s Office said a prosecutor from its regional unit had formally opened an investigation into the previous day’s events. In a post on X, it said the evidence pointed to one person carrying out both the shooting in Krakow and the killings of three people in Ostrowiec Świętokrzyski. The office’s wording matters: the link is the investigators’ assessment based on evidence collected so far, not an independently established conclusion by a court.
The same statement separated the legal scope of the two scenes. The Krakow case covers the killing of six people and attempted murder of many others, including police officers, and says the act had a terrorist character. The Ostrowiec case concerns the killing of three people with a firearm under Article 148 §3 of the Polish Criminal Code. The statement therefore does not say that all nine deaths have been charged as one terrorist offence. That distinction is central to the updated account.

What the terrorism classification means
Justice Minister Waldemar Żurek, who is also Poland’s prosecutor general, said the alleged purpose of the Krakow attack was to seriously intimidate a large number of people, the basis cited for the terrorist classification. Prime Minister Donald Tusk had also described the incident at Saturday’s briefing as one of the most drastic cases of terrorism Poland had faced. The minister’s statement is the prosecution’s legal theory at the investigative stage, distinct from the prime minister’s political description. It has not been tested in court, and it does not settle why the suspect acted, whether the ideology cited by officials drove the attack, or whether the deaths at the family home had the same motive.
Waszczuk told TVP Info that prosecutors planned to issue the formal order on Sunday. The National Prosecutor’s Office later confirmed that it had opened the case. dpa also reported the terrorism investigation, while noting that the motive remained unclear. The procedural shift is significant: the formal case is now open.

The suspect and unresolved weapons questions
Polish media have identified the suspect as Michał O., a 24-year-old Polish citizen from Ostrowiec Świętokrzyski. Polskie Radio 24 reported that he worked as a lathe operator; the defence minister said he had never served in the Polish Armed Forces. The Associated Press used a different age, describing him as 25; the discrepancy has not been reconciled publicly. The name remains in the abbreviated form used by Polish outlets. Authorities have said he acted alone, but the investigation remains open.
Wirtualna Polska reported that Michał O. held a sports firearms licence and belonged to a shooting club in Starachowice, where his father was also a member. The outlet reported that the father had 11 firearms registered and that the suspect had two registered to himself. RMF FM reported that police described the weapon used in Krakow as a civilian version of an AR-15. The club later said it had not trained him in dynamic, tactical or combat shooting. Police have not established publicly whether the rifle was registered to the suspect or his father, came from another source, or had been modified.

Nine people are dead; two officers are named
Six people were killed in the square: four women and two men. The Prime Minister’s Office said three of the women were Polish and one victim was a British citizen, while two identities were still being established in its 7 November statement. RMF FM reported on Sunday that the victims included a British citizen and that 15 people had been shot and wounded. Three more people were found dead at the family home: the suspect’s father, 53, mother, 52, and sister, 21. Police said all three had injuries preliminarily identified as gunshot wounds.
Two police officers wounded during the intervention have been named as Senior Constables Jakub Kulik and Artur Morański. RMF FM reported that both were hurt while confronting the gunman. A police appeal for AB Rh+ blood described Kulik as fighting for his life; a separate update from the Interior Ministry said one officer was stable and the other in serious but stable condition, without matching those statuses to the names. Injury totals vary because some reports count the suspect among the wounded: RMF FM and AP reported 15 injured, while the Prime Minister's Office counted 16, including the suspect; Reuters and The Guardian reported 17. AP reported five foreign nationals among the wounded, from Austria, Germany, Portugal, Russia and Britain, citing an interior ministry spokesperson. Those figures should remain attributed rather than merged.

Motive remains unproven as cyber investigators examine activity
Officials have described the suspect as appearing influenced by far-right or ultranationalist views. Interior Minister Marcin Kierwiński called his views very radical, while AP and Reuters reported the government’s assessment that he appeared to be fascinated by far-right ideology. These descriptions are official assessments, not a proven motive. Prosecutors have not publicly explained what drove the attack, and the legal label attached to the Krakow case cannot substitute for evidence about the suspect’s intent.
The Central Bureau for Combating Cybercrime is examining his online activity, according to Polish reporting, as investigators look for possible extremist connections and signs that might clarify his thinking. No public finding from that analysis has established a motive or a wider network. The shooting club’s statement that it did not provide tactical or combat training also does not answer what happened at either scene. Investigators will need to test digital material, witness accounts and forensic evidence against each other.

Separate mourning periods and the next investigative steps
Poland is observing national mourning on 8 and 9 November, following the president’s decision. Krakow’s mayor separately announced city mourning through 11 November, with flags draped in black and municipal events cancelled. The two periods are distinct: the national order covers Sunday and Monday, while the city’s measure continues for several more days. The Main Market Square, a central public space, has remained a focus of remembrance as well as an active investigative site.
The next steps will depend on forensic work, interviews and the suspect’s medical condition. The Prime Minister’s Office said he was shot by police and taken to hospital; local reporting described him as being under guard. Prosecutors have now linked the two locations in their working account, but a formal investigation is not a final judgment. The deaths of nine people are confirmed; responsibility, motive and the full sequence of events must still be established through the legal process.
