Officials said 47-year-old Kristopher Karolkiewicz fatally shot his wife, 39-year-old Amanda, and his six kids before shooting himself inside the burning home.

Officials were still investigating the cause of the fire, but said they believe the fires were intentionally set in multiple areas of the home.

Officials did not identify the children, but said four were boys, ages 15, 12, 11, and 5, and two girls who were both 11 years old. Two of the children were adopted, officials added.

Grand Haven Area Public Schools announced it would be providing support for students and staff impacted by the family's deaths.
