5 killed in shooting in Switzerland, police say

Five people have been found dead after a shooting in northern Switzerland that may have resulted from a family dispute, police said Sunday. The dead included the suspected gunman.

Residents heard shots in the small town of Wuerenlingen northwest of Zurich shortly after 11 p.m. Saturday, leading police to find five bodies in a residential neighborhood.

The shooting appears to have been a "relationship crime," Aargau canton (state) police chief Michael Leupold told reporters, adding that investigators ruled out any links to terrorism.

The suspected gunman first killed three people -- a 57-year-old man, a 59-year-old woman and a 31-year-old man -- inside a house, police said. As he walked toward his car, he shot and killed a neighbor before shooting himself.

The victims in the house were the parents-in-law and brother-in-law of the suspected gunman, a 36-year-old who lived in Schwyz canton, south of Zurich, and was reportedly separated from his wife. All were Swiss.

It wasn't clear whether the gunman knew the neighbor, a 45-year-old man, and the exact motive for the slayings also remained unclear.

Police said the gunman used a pistol that was not an army weapon. Switzerland has a long-standing tradition of men keeping their military rifles after their compulsory military service.
