The man barged into a birthday party early Sunday, Mar 15 shot his estranged wife and three other people to death, then went home, set his truck and house on fire and killed himself, police said.
The police learned of the shootings on Sunday, Mar 16 morning. They apparently stemmed from sort of domestic dispute.
Cops got a call shortly after midnight that numerous shots had been fired. Police found four bodies on arriving at the spot.
The names of the victims and gunman haven't been released because family members haven't been notified.
Police say the gunman may have been angry because his wife had left him, but they're still investigating. The house where he killed himself is about 5 km from the house where the shootings happened.
