Manhunt continues after Swiss rave shooting in Aarau

A shooting at a techno rave at the Schachen horse racing track in Aarau killed a 22-year-old woman and wounded five other Swiss residents on a night that sparked a large manhunt and surrounding-area closures. Investigators said the motive was unclear and kept multiple scenarios open, including terrorism, a rampage, or a criminal act, with authorities stressing the investigation was in the early stages. Italian Prime Minister Giorgia Meloni identified the deceased as Maria Spinelli and offered condolences; Swiss President Guy Parmelin and other officials likewise expressed sympathy. Police indicated the shooter may have acted alone, but acknowledged they were evaluating all possibilities as the investigation continued. A 43-year-old Swiss man was arrested shortly before 1:00 a.m. local time on Monday in connection with the case, bringing a development to the ongoing inquiry. The killings occurred during a rave at the venue, where cartridge casings suggested multiple calibers were used, and authorities urged the public to stay away as they gather evidence.
