Loosely coordinated firebugs.
[ATSOS: Arson Terrorists Shot On Sight]
[Oregon] Multnomah County Sheriff:
We are at a loss for words. Deputies & Corbett_Fire responded to a small brush fire in the 1700 block of NE Brower Rd in Corbett at 3:52pm. Neighbors heard pops and saw 6ft flames in the forest. Using a shovel and water, they were able to put it out. Deputies found fireworks...
The fireworks were placed about 100-150 yards off the road. Deputies are conducting high visibility patrols in rural Multnomah County. Corbett_Fire will remain in the area. If you have any information on this, call the non-emergency line. If you see an active fire, call 911.
