Three arrested in drug bust on Pullman's College Hill

Update: Pullman Police arrested a 19-year-old Cheney man Monday suspected of arson in connection to the fires that were ignited around a Washington State University fraternity house.

Detectives developed leads using surveillance video and interviews with Theta Chi members. That led to the arrest of 19-year-old Isaac DePaolo in Cheney with assistance from Eastern Washington University and Cheney Police.

Pullman Police say a motive for the arson has yet to be determined, but they believe alcohol may have been a factor.

DePaolo, a Cheney resident, is not a student at WSU or EWU. He was booked into Whitman County Jail Monday afternoon on multiple arson charges along with a vehicle prowling charge.

Previous coverage: Pullman fire and police crews are investigating what they call a number of suspicious fires around a fraternity house near the Washington State University campus early Sunday morning.

A fire destroyed a wooden deck behind the Theta Chi fraternity house, and there were multiple fires discovered around the brick structure.

Several frat members said they were awakened around 5:15 a.m. by the sound of the deck fire. They called 911 and tried to extinguish the fire with a garden hose to prevent it from moving up the multi-story house.

Firefighters arrived and extinguished the fire, but the deck was destroyed. Frat members had doused a fire at the front of the house with a garden hose. A fire investigator discovered an attempted fire in the patio area, and found five different ignition points around the house.

In addition to the deck being destroyed, there was some heat damage to a Honda vehicle and a dumpster near the deck. A window in the back of the house was broken from the heat as well.

No injuries or other damage to the house was reported. Investigators interviewed frat members and police are gathering evidence. They say there are no suspects at this time.
