A Kansas family of six is dead after the 53-year-old father killed his wife and four children before turning the weapon on himself.

Authorities who responded to the home in Winfield, Kansas, found six people dead inside, including three girls and one boy between the ages of 3 and 9.

The children were identified as girls ages 9, 5 and 3 and a boy, 7. An official said the father had been reported for “aggressive behavior” in the past.
