Polish police investigate Krakow mass shooting after suspect dies

Polish authorities are continuing their investigation into Saturday's mass shooting in Krakow following the death of the 24-year-old suspect, identified as Michal O., in hospital on Monday.

Police confirmed that the gunman opened fire from a vehicle on bystanders in Krakow's main square using a civilian variant of a semi-automatic AR-15 rifle. The attack left six people dead and at least 17 injured before officers shot and critically wounded the suspect.

Investigators subsequently discovered three bodies—believed to be the suspect's parents and sister—at his family residence. Polish Prime Minister Donald Tusk described the home discovery during an emergency crisis meeting as "the next act of this tragedy." Polish President Karol Nawrocki declared Sunday and Monday as days of national mourning as the country seeks answers.
