A 21-year-old gunman who tragically killed 10 people at a school in Graz, Austria, was revealed to be an 'obsessive online first-person shooter' by the police. This new information sheds light on how meticulously he planned the attack.

The young Austrian, who took the lives of 10 individuals before ending his own life, was known to spend a significant amount of his free time engrossed in 'ego shooting' video games online. These games involve using virtual firearms to eliminate enemies, and police believe that this virtual community was his primary social circle, as he was otherwise a solitary individual.

Among the victims was one of his former teachers, although it remains unclear if she was deliberately targeted. The casualties included the 59-year-old teacher and nine students, six female and three male, aged between 14 and 17. While nine individuals are still receiving treatment for their injuries, all are in stable condition, with the last two in intensive care expected to be moved out during the day, according to health officials.

It was also revealed that the perpetrator had recently failed a psychological evaluation to join the military, but had passed the necessary checks to legally possess the weapons used in the attack. The man, who had dropped out of the school three years prior, was an apprentice at an industrial school and lived with his mother. He had no prior criminal record.

The shooting incident, the deadliest in Austria's history, has sparked discussions about the country's gun laws. During a visit to Graz, Austria's president called for a review of the laws, questioning how a 21-year-old could own firearms and ammunition legally. The national security council was set to address the issue, and talks have begun about enhancing security measures in schools.

Michael Lohnegger, the head of the Styrian state criminal police office, detailed the meticulous planning of the attack. The gunman entered the school premises carrying a backpack with weapons and ammunition, proceeding to carry out a seven-minute rampage through the school before taking his own life.

Despite the tragedy, there is no evidence that the killer knew the victims personally, and investigations are ongoing to determine if he had an accomplice. The community is mourning the loss of the victims, including a 15-year-old Bosnian-Austrian girl and a 15-year-old girl of Kosovar descent.

Details of the victims have begun to emerge, with families and communities devastated by the senseless act of violence. The tragic event has left a deep impact on the nation and sparked important conversations about gun control and school safety.
