Swiss authorities announced the arrest of a 43-year-old individual connected to a fatal shooting at a rave in Aarau over the weekend. The tragic incident resulted in the death of a 22-year-old Italian woman and left five others injured during the early hours of Sunday at a horse racing track venue.
Following an extensive operation, law enforcement apprehended a 43-year-old Swiss male just before 1 a.m. on Monday on suspicion of perpetrating the attack. Investigations are ongoing to determine the precise events surrounding the incident, along with any potential motives behind the violence. Authorities in the canton of Aargau shared that it is believed a sole perpetrator was responsible, although no further details have been disclosed at this time.
Authorities are exploring three potential motives for the shooting, including the possibility of it being a mass shooting, an act of terrorism, or a motive that remains unidentified. Evidence found at the crime scene, specifically cartridges, suggested the use of two different bullet calibers, indicating the potential use of a pistol and a larger weapon, possibly an assault rifle.
While the Swiss newspaper Tages-Anzeiger mentioned similarities between the cartridges found and those typically associated with the Russian AK-74 assault rifle and its variations, police have refrained from commenting on this specific detail. The victim, identified as Maria Spinelli by Italian Prime Minister Giorgia Meloni, was the 22-year-old Italian national who tragically lost her life in the incident.
