The family of the four people who died in a Rapid City apartment fire Tuesday night has set funeral arrangements for the middle of next week.
Funeral services for Marcia Rock and her three grandsons will be held Wednesday at the Mother Butler Center in Rapid City.
Rock was an Army veteran, and will be buried at the Black Hills National Cemetery.
Her grandchildren will be buried at the Makasan Presbyterian Cemetery in Oglala.
Rock and her grandsons, 9-year-old Thomas Rosado, 5-year-old Dustin Rosado and 3-year-old Marquez Hawk Wing, died of smoke inhalation.
The Rapid City Fire Department said a preliminary investigation indicates the fire was "human caused," but added a full investigation could take months.
