The 24-year-old gunman suspected of killing six people in central Krakow and his own family members has died in hospital, Polish police announced Monday.

The suspect was injured during a gunfight with armed officers shortly after opening fire in the city's Main Market Square on Saturday, and succumbed to his injuries early Monday morning.

Six people—four women and two men—were killed in the attack. Four victims were Polish nationals, while a British citizen and an Austrian woman also died. The suspect's parents and 21-year-old sister were found dead at their home following the shooting.

Authorities are continuing to investigate the motive behind the attack, with initial suggestions of far-right ideological inspiration now being re-evaluated. Przemysław Nowak, spokesperson for Poland's National Prosecutor's Office, stated that investigations into the motive remain ongoing.

During a search of the suspect's home, police discovered the bodies of his father, mother, and sister. Polish media reported that the suspect possessed a firearms permit and may have obtained the weapons from his family residence. Four firearms, including two AR-15 rifles and two handguns, along with hundreds of rounds of ammunition, were found in the attacker's car.

Sixteen individuals, including the attacker, were hospitalized following the incident. Among the injured were five foreign nationals from Austria, Britain, Germany, Portugal, and Russia, as well as two police officers. Surgeons who were present near the scene rushed to provide medical assistance to the injured, including a police officer who was critically wounded.

The shooting began shortly before 3:00 PM local time on Saturday in the busy Main Market Square. Police responded rapidly, engaging the suspect within three minutes of the attack commencing, which officials believe prevented further casualties.

Investigators have seized multiple phones and electronic equipment from the suspect's car and home as part of the ongoing inquiry into the events that have shaken Krakow.
