A gunman in Krakow killed his family and two pet cats before the attack. Each of those people died from two gunshots to the head, a spokesman for the Polish prosecutor's office, Przemyśław Nowak, told Virtualana Polska.
According to the initial conclusions of the investigation, the perpetrator killed his family members "on the night from Friday to Saturday or on Saturday morning." This is indicated by the clothing and placement of the bodies.
