Overview
- A 22-year-old woman was killed and five people in their 20s were wounded when shots were fired at the Aarauer Rave at the Schachen horse-racing track on Sunday morning.
- Police arrested a 43-year-old Swiss man shortly before 1 a.m. on Monday on strong suspicion of carrying out the attack and now treat the case as an ongoing criminal investigation that likely involved a lone perpetrator.
- Investigators recovered shell casings at the scene that indicate two different calibres of ammunition, prompting forensic work to determine whether a handgun and a larger weapon were used and to establish the shooting’s precise sequence.
- Authorities mounted a large emergency response with cordons, a military helicopter, special units and cross-border assistance from German police, and they have appealed to attendees for photos and video to help the probe.
- Reports differ on victim identity because Swiss privacy rules restrict early naming; Italy’s prime minister named the deceased as Maria Spinelli and the incident, rare in Switzerland, could prompt reviews of event security and policing at large public gatherings.
