A football party in Plano, Texas turned deadly when a gunman opened fire and killed seven and injured two people.
The first responding police office engaged in a shootout with the suspected gunman.
It is believed the shoot-out was prompted by a “domestic dispute” at the party for fans of NFL team the Dallas Cowboys.
People at the party were watching the game when the violence started.
When the first police officer arrived on the scene just after 8pm in a suburb north of Dallas, he saw bodies on the ground and the suspect shot at him.
The officer exchanged fire with the gunman, fatally wounding him.
One witness said she heard between 30 and 40 shots fired around 8pm local time.
Police found seven bodies inside the house.
