AARAU, Switzerland (Reuters) - A gunman killed three relatives and a neighbour in a late-night
rampage in a Swiss village before turning his weapon on himself, local police said on Sunday.
The presumed killer, a 36-year-old Swiss national who was separated from his wife and the couple's three children, shot dead his father-in-law, mother-in-law and brother-in-law, police told a news conference.
The killings took place late on Saturday in and around a residential building in Wuerenlingen, a community of some 4,500 people north-west of Zurich.
Police said the gunman lived in another part of Switzerland and was known to police for violent behaviour. The murder weapon was unregistered, they said.
A neighbour, who was not identified, told Swiss newspaper Blick she heard four shots in succession fired very quickly, then two further shots after a pause. She had heard no screams, the tabloid reported.
