Five people are dead following a mass shooting in Switzerland.
The presumed killer, a 36-year-old man separated from his wife and children, shot and killed his mother and father-in-law, as well as his brother-in-law and a neighbor before turning the gun on himself.
Bernhard Graser is with the local police in the community northwest of Zurich.
He says they are working under the assumption it is a case of domestic violence.
"We started the investigation and so far we know five people are dead. The background of this crime is probably some familiar relations, problems within the family, that is part of the investigation that is going on at the moment."
Authorities say the 36-year old attacker had a history of violent behavior.
