Residents of the Czech Republic were left horrified this week after a man murdered fifteen people and left more than a dozen injured. 

According to the New York Post, 24-year-old David Kozák fatally shot his father on Thursday morning in a small town known as Hostoun.

Police chief suggests shooter may have been inspired by Russian terror attack

The killer then traveled east to Prague where he opened fire on students at Charles University's Faculty of Arts around 3:00 p.m. local time.

Authorities say Kozák proceeded to kill 14 victims at the university and wound another 25 before apparently ending his own life, although it is possible that he may have been hit by gunfire from police.

Czech Interior Minister Vit Rakusan indicated that Kozák is not believed to have been tied to any extremist ideology or organizations.

However, Police Chief Martin Vondrasek was quoted as telling reporters that there is "unconfirmed information from an account on a social network that he was supposedly inspired by one terrorist attack in Russia in the autumn of this year."

"It was a premeditated horrific act that started in the Kladno region and unfortunately ended here," the law enforcement official said of Thursday's tragedy.

Killer expressed hate for the world in social media post, complained of ear problems

Vondrasek went on to say that Kozák is also suspected of having murdered a man and his 2-month-old daughter near a village outside of Prague.

The Post noted that Kozák had an account with the social media platform Telegram on which he made a number of disturbing comments. Among them was a post in which he expressed hate for the world along with a desire "to leave as much pain as possible."

In another post made just two days before the rampage, Kozák complained of experiencing a "ringing" sensation in his ears and declared that he wanted to "rip" them out.

Prague Mayor Bohuslav Svoboda was quoted as telling Czech Television, "We always thought that this was a thing that did not concern us."

"Now it turns out that, unfortunately, our world is also changing and the problem of the individual shooter is emerging here as well," Svoboda went on to lament.

Dramatic footage posted to YouTube showed crowds of terrified university students running while others attempted to hide on a narrow ledge outside of a window.
