Poland began two days of national mourning on Sunday, after a 24-year-old man with far-right views drove into a busy central square in Krakow and opened fire, killing six people and wounding 15 others before police shot and wounded him.
The attack, which Poland's defense minister described as an "act of terror," happened on Saturday in Main Square, which is in the heart of Krakow's Old Town and is a major tourist hub in the country's second-largest city.
By evening, mourners had left candles in memory of the victims. The square remained partially closed on Sunday morning as authorities continued their investigation.
St. Mary's Trumpet Call, a traditional five-note melody played every hour from the highest tower of St. Mary's Basilica on the Main Square, was paused overnight in tribute to the victims. It is the first time the call has been missed since World War II.
Authorities also found the bodies of the assailant's sister, mother and father at the man's family home in Ostrowiec Świętokrzyski, a city about 150 kilometers (93 miles) northeast of Krakow. They likely died from gunshot wounds.
