Five people have been found dead after a shooting in a town in northern Switzerland, police say.
Residents heard shots in the town of Wuerenlingen shortly after 11pm local time on Saturday, police said.
Officers then found five bodies, including that of the suspected attacker, in a quiet residential neighbourhood.
The shooting appears to have been a "relationship crime", or the result of domestic dispute, Michael Leupold, Aargau canton (state) police chief, said.
Police "were able to rule out a terrorist background" or any other danger, he said.
The suspected attacker first killed three people - a 58-year-old man, a 57-year-old woman and a 32-year-old man - in a house, criminal police official Markus Gisin said.
He is then believed to have killed a 46-year-old neighbour outside the house before shooting himself.
The victims in the house were the parents-in-law and brother-in-law of the suspected attacker, a 36-year-old who lived in Schwyz canton (state), south of Zurich. All were Swiss nationals.
The assailant's wife and three children were not targeted in the shooting.
Wuerenlingen is a town of some 4,500 people northwest of Zurich, near the German border.
