Police in Pullman are investigating several suspicious fires set outside a fraternity house near the WSU campus.
Investigators found five different ignition points around the Theta Chi frat house early Sunday.
One of the fires destroyed a wooden deck at the back of the house.
The fraternity was not damaged and no one was hurt.
Several fraternity members say they woke up around 5:15 a.m. because of the sound of the deck fire. They called 911 and tried to put it out with a garden hose.
Police say there are no suspects at this time.
