CLACKAMAS COUNTY, Ore. — Newly-released drone video from the Clackamas County Sheriff’s Office shows part of the Aug. 29 standoff that led to the arrest of Erik Gordon Shunn, including Shunn firing at a sheriff’s drone before SWAT personnel take him into custody. The short video first shows Shunn sitting on the ground and firing at a CCSO drone. It later cuts to Shunn driving a tractor near the front of his home as a sheriff’s SWAT vehicle moves in and pins the tractor. According to the sheriff’s office, SWAT personnel made the decision to rush in after Shunn got on the tractor and left his rifle behind. Authorities said officers used that window of opportunity because they thought it was likely their best chance to safely take him into custody. The confrontation began after deputies responded to South Rocky Bluff Lane in unincorporated Oregon City on Aug. 29. The sheriff’s office said the 53-year-old Shunn allegedly fired around 20 rounds toward workers cutting down trees. Authorities evacuated the area and issued shelter-in-place alerts as deputies surrounded Shunn’s home. The sheriff’s office said a drone spotted Shunn using a tractor to knock down trees in an apparent attempt to create a barricade. Authorities also said Shunn fired several shots at sheriff’s office drones, which was shown in the video released Wednesday. No one was injured, including Shunn’s mother, who was inside the home during the incident. Shunn was taken to a local hospital for evaluation. Shunn is booked in the Clackamas County Jail on several charges including two felony counts of second-degree attempt to commit a crime , recklessly endangering another person, unlawful use of a weapon and menacing.
