(Portland, OR) -- Two fires in Northeast Portland are being called suspicious. That's according to fire investigators who say it's due to the timing and locations of the fires yesterday morning. The first fire was around 2:30 in the morning at an abandoned car wash on Northeast Martin Luther King Jr. Boulevard. Upon arrival, investigators say firefighters found tents and other camping supplies on fire. About two hours later, firefighters were called to a dumpster fire, just two blocks away from the car wash fire. That fire spread to a neighboring home, which was badly damaged. Anyone with any information is asked to call the PFR tip line at 503-823-INFO.
