A 43-year-old Swiss man was arrested on Monday morning in connection with a deadly shooting at a rave in Aarau, Switzerland, that left one woman dead and five others injured. The 22-year-old Italian woman, Maria Spinelli, was killed in the early hours of Sunday morning, while four men and a woman between the ages of 24 and 27 were taken to the hospital with injuries ranging from minor to severe. The shooting occurred at a covered horse racing track in Aarau, where hundreds had gathered for the event. Police launched a massive operation after receiving reports of shots fired, and arrested the suspect just before 1am on Monday. Cartridges found at the scene suggested that two types of bullets were used, possibly from a pistol and an assault rifle. The police are investigating three possible motives for the shooting: a mass shooting, an act of terrorism, or an unknown criminal motive.
