On 21 December 2023, 14 people were killed and 22 injured in a mass shooting at the main Faculty of Arts building of Charles University in central Prague, Czech Republic. Another three people were injured when the perpetrator opened fire toward the streets from the faculty's fourth-floor rooftop terrace.[7][8][9][10][11][12] After having been engaged by the police, the perpetrator, 24-year-old postgraduate student David Kozák, committed suicide by shooting himself.[13][14][15] Before the attack, his father was found murdered at his home in Hostouň.
At the time of the shooting, the perpetrator was one in a pool of about 4,000 suspects in a double murder case that took place six days earlier, 25 kilometres (16 mi) away, when a father and his infant daughter were murdered in Klánovice. The lead investigator confirmed that the police had not yet reviewed the perpetrator's potential as a suspect in the earlier killings when the Prague shootings took place. Still, evidence found in the latter event did link the two incidents.
