An argument during what was supposed to be a happy family dinner outside Moscow turned into a massacre when a man shot and killed nine people, investigators revealed on Sunday.

Survivors told police the suspect had quarreled with others at the dinner in Redkino on Saturday night, left the cottage, returned with a hunting rifle and opened fire.

The suspect has been arrested, according to the Investigative Committee. It did not give his name but stated he was born in 1974 and lived in Moscow, AFP reported.

He had been "drinking spirits," investigators added.
