The Austrian authorities were searching for answers on June 11 as to why a 21-year-old gunman shot dead 10 people in a rampage at his former high school before killing himself, one of the worst outbreaks of violence in the country’s modern history.

The police said the man, armed with a shotgun and a pistol, acted alone. They are scouring his home and the internet for clues as to why he opened fire on the school in Austria’s second city of Graz on June 10, before shooting himself in a bathroom.

The incident was hard to properly take in, said a religious studies teacher at the school, Mr Paul Nitsche, who left his classroom before the gunman tried to enter, and briefly saw him trying to shoot the lock off another door.

“This is something I couldn’t even imagine before,” he told national broadcaster ORF. “That’s what the situation was like as I ran down the stairwell. I thought to myself this wasn’t real.”

Some Austrian media outlets said that the young man, who has not been identified, apparently felt bullied, though the police have yet to confirm this. The Austrian authorities said the suspect never completed his studies at the school.

He left a farewell note that did not reveal the motive for the attack, the police said, adding that a pipe bomb found at his home was not functional.

Ennio Resnik, a student at the school, said students and teachers needed time to come to terms with what had happened, and asked that they be left in peace for a few days.

“It’s surreal, you can’t describe or really understand it,” he said, speaking to reporters outside an events centre near the school where students were being offered counselling. Some of the students gathered there cried, while others held one another.

Second school threatened

Dr Franz Ruf, director-general of public security, said probes into the motive were moving swiftly.

“We don’t want to speculate at this point,” he told ORF on the night of June 10.

The police were on the alert for potential copycat attacks and they had received a threat against another school in Graz late on June 10, he said.

In the earlier attack, about 17 minutes elapsed between the first emergency calls received by the police about shots being fired at the school and the scene being declared safe, Dr Ruf said.

Austria has one of the most heavily armed civilian populations in Europe, says the Small Arms Survey, an independent research project.

The attack sparked calls for its gun laws to be tightened, including one from Graz’s mayor.

The police said the guns used were in the suspect’s possession legally, and Dr Ruf said that while Austrian gun laws are strict, the case was being looked into.

“If there are any loopholes, they need to be closed,” he said.

Details of the attack have emerged slowly.

The Austrian police said victims were found both outside and inside the school, on various floors. About a dozen people were injured in the attack, some seriously.

Austria declared three days of national mourning, with the shootings prompting a rare show of solidarity among often bitterly divided political parties.

Parents of students and neighbours of the school struggled to make sense of the event.

Hundreds came together in Graz’s main square on the evening of June 10 to remember the victims. Others left flowers and lit candles outside the school.
