HILLSBORO, Ore. -- A home in Washington County's Bethany neighborhood went up in flames early Monday morning under suspicious circumstances, according to Tualatin Valley Fire & Rescue.

Two fires in August have been ruled arsons. Then a suspicious fire destroyed a home on Nov. 22. Those and the home set ablaze Monday morning were nearing completion.

Firefighters were dispatched about 12:40 a.m. after a Washington County Sheriff's Office deputy spotted flames in the home in the 7800 block of Northwest 169th Avenue, said Chief Cassandra Ulven.

In addition to first directly fighting the fire from inside the home, firefighters fought flames from inside an adjacent home.

Additional crews were sent to help at about 1 a.m. Aerial ladder trucks poured water onto the burning home, Ulven said. Freezing temperatures made for slick conditions.

The home was declared a total loss. And adjacent home had minor fire, smoke and water damage. Investigators continued to pour over the scene more than 12 hours after the fire was reported.

"These things are probably not as easy to prevent but you need to build the confidence so that people can sleep at night in comfort, knowing that somebody is watching (out) their back... this is very unsettling," said one neighbor who was so on edge by the fires he asked us not to identify him.

Anyone with information should call the sheriff's office at 503-846-2700. Deputies and a private security company have been patrolling the neighborhood.

  • The third took place on November 21 near the intersection of NW 167th and NW Catalpa St.
  • In all cases, firefighters from Station 64 were first to arrive and were met by a large amount of fire.
