Overview
- A 22-year-old woman died at the scene and four men and one woman, aged 24–27, were taken to hospital after shots were fired at the Aarauer Rave in Aarau's Schachen district.
- The shooting occurred around 2:30 a.m. on Sunday, Aug. 30, during the annual techno event held at the covered horse racetrack that organisers expected to draw about 3,500 people.
- Aargau cantonal police launched a large-scale manhunt that has cordoned wide areas, deployed armed officers and an army Super Puma helicopter, and asked the public to share photos and video.
- Authorities have not identified suspects, have not confirmed how many attackers were involved, and say possible motives — including terrorism, a mass attack or other criminal causes — remain under investigation.
- Swiss reporting notes the rarity of public shootings in the country despite widespread gun ownership, and investigators say recovered cartridges suggesting two calibres are part of a developing forensic inquiry.
