At least eight people are dead, including the suspect, after a shooting at a home in a Dallas suburb, authorities said.
The shooting occurred about 8pm Sunday (local time) in the city about 32km northeast of Dallas.
Plano police spokesman David Tilley said police initially responded to a report of shots fired. When the first officer arrived and went inside the home, the officer confronted the suspected shooter.
The officer opened fire, Tilley said, killing the suspect. Two others were injured in the shooting. Their conditions were not released.
The victims and suspect have not been identified. All of those killed and injured were believed to be adults.
