According to cantonal police, the situation is stable for all five, and there appears to be no connection between them other than the fact that they were all on the reef.
A 22-year-old Italian woman was killed when one or more perpetrators fired shots on the reef in Aarau at 2:30 a.m. on Sunday.
No one has yet been arrested in the case, and police still do not know the motive, but they are working on three hypotheses: terrorist attack, mass murder and an ordinary criminal act. On Sunday, police found ammunition from two weapons - a submachine gun or pistol and a more powerful rifle.
