Swiss police say the fatal shooting at a rave in Aarau over the weekend was an amoklauf, or rampage, and that the attack appears to have been carried out by a single gunman.
The revised assessment came after officers gathered additional information in the days following the attack at a techno event in the canton of Aargau. According to the police, the suspect fired more than 40 shots during the night into Sunday, first using a Kalashnikov-style weapon to shoot indiscriminately at people and then firing a pistol at a car. The man, a 43-year-old Swiss national, was arrested roughly 24 hours later.
Police chief Michael Leupold said investigators now believe with near certainty that there was only one attacker and that there is no indication of any further people taking part. He also said there is no current danger to the public. That is a notable shift from the hours immediately after the shooting, when the possibility of multiple perpetrators had not yet been ruled out and a large-scale manhunt was under way with help from German authorities.
One 22-year-old woman was killed in the shooting on the grounds of the Aargau racing club site where the event was held. Five people between the ages of 24 and 31 were injured. A sixth person later came forward with injuries from a ricochet, according to police. Two of the injured remained in hospital, and one of the victims is reported to be German. All of the injured live in Switzerland.
The police said the suspect has not explained a motive. However, statements he made to investigators reportedly suggested possible mental health problems. That remains a working inference rather than a formal conclusion, and police have not yet linked the attack to a political or criminal organization. The force is also still examining whether there could have been any terrorist element, even though the current assessment points to a lone offender.
The case has drawn attention because it sits at the intersection of several fears that can follow a mass shooting: a random attack in a public space, uncertainty about motive, and the possibility of an ideological angle. Investigators initially considered multiple possibilities, including a rampage, a terror attack and a possible settling of scores in the criminal underworld. The latest police statement narrows that field substantially, but it does not explain why the suspect opened fire.
The shooting also triggered a cross-border response. The scene in Aarau lies close enough to the German border that neighboring authorities were drawn in during the early hours of the search. That cooperative effort now appears to have been part of a rapid effort to contain a case that could otherwise have escalated into a wider public safety scare.
For the communities around Aarau, the most immediate reality is the loss of a young woman and the injury of others at what should have been a nightlife event. For Swiss police, the case now looks less like a coordinated attack than a violent outburst by a single suspect. Even so, the investigation remains open, and the unanswered question at its center is not only how the shooting was carried out, but why.
