Officials to investigate Heritage University fire next week

TOPPENISH, Wash. -- Investigators won't be able to release the cause of the fire at Heritage University until next week.

Deputy Fire Marshall Ron Rutherford says his team won't go onto the site until Monday.

Rutherford says they needed to let the building cool naturally without any more water to keep the burn patterns intact.

Inspectors will go in Monday to remove components from the building to trace the source point of the fire.
