A 53-year-old man allegedly opened fire on a crew of arborists cutting down trees on South Rocky Bluff Lane in unincorporated Oregon City on Saturday afternoon, firing approximately 20 rounds before barricading himself with a tractor and shooting at sheriff's drones during a tense standoff that ended with his arrest roughly 80 minutes later. No one was injured, according to authorities.
The Clackamas Sheriff announced in a news release that deputies and SWAT responded to a report of an armed subject in the area, confirming the suspect was ultimately taken into custody without harm to the public. According to KGW-TV, the emergency call came in at 2:24 p.m. Saturday, with initial 911 callers warning deputies that the man, identified as Erik Gordon Shunn, was believed to possess multiple firearms.

During the standoff, sheriff's drone operators spotted Shunn in his driveway using a tractor to knock down trees, apparently in an attempt to construct a barricade, the station's report states. Shunn reportedly fired several shots directly at the police drones overhead, though no officers or bystanders were struck during any of the gunfire.
Evacuations Held While Mother Remained Inside
Shunn's mother remained inside the home throughout the standoff, but first responders managed to evacuate nearby neighbors and the tree workers without any reported injuries, per the same account. SWAT operators and Crisis Negotiation Teams handled the perimeter evacuation, and the Clackamas Sheriff's release similarly noted that the armed subject incident created no further danger to the public and that SWAT was clearing the scene as the situation wound down. The sheriff's release also identified the suspect as a neighbor in the area and instructed the public to avoid South Rocky Bluff Lane while the operation was underway.
SWAT took Shunn into custody shortly before 3:45 p.m. Saturday, after which he was evaluated at a local hospital before facing booking, the article notes. Charges are expected to include second-degree attempted murder and attempted first-degree assault, along with recklessly endangering, unlawful use of a weapon, and menacing.
Mandatory Minimum Sentencing Looms Over Case
If convicted of attempted second-degree murder, Shunn would face a mandatory minimum prison sentence of 7 years and 6 months without eligibility for reduction under Oregon's Measure 11 sentencing framework, according to Rhett Bernstein Law, which notes that Measure 11 mandatory minimums apply strictly to major violent felony offenses in the state. Separately, the unlawful use of a weapon charge — defined under Oregon Revised Statutes 166.220 as discharging a firearm at or toward a person, structure, or vehicle within urban growth or residential areas — is classified as a Class C felony carrying up to five years in prison, per Gilroy Napoli Short Law Group, which adds that statutory exemptions exist only for authorized law enforcement duties or lawful self-defense.
The Clackamas County Sheriff's Office holds primary law enforcement jurisdiction over the more than 87% of the county's 1,879 square miles that consists of rural or unincorporated land, according to Clackamas County, which notes the county is Oregon's third most populous with over 420,000 residents. That rural jurisdictional reality is part of why county deputies and SWAT, rather than a city police department, were the ones who responded to the shots-fired call in unincorporated Oregon City.
Suspect Previously Drew Media Attention in 2016
Shunn is not unfamiliar with news coverage. In 2016, he received media attention when his brother, Patrick Shunn, and sister-in-law were murdered in Snohomish County, Washington, prompting public appeals from Shunn during a multi-state search for the killers, according to KIRO 7 News. That earlier case stemmed from a high-profile rural property dispute, the outlet reported at the time.
Saturday's standoff was not the first time SWAT and Crisis Negotiation Teams have been deployed to a barricaded gunman in unincorporated Clackamas County. In July 2025, a similar response in unincorporated Milwaukie ended with negotiators successfully talking a resident who had fired shots inside a house into surrendering, illustrating how the sheriff's office routinely pairs SWAT operators with negotiation specialists in these rural standoffs. Hoodline previously covered a fatal Happy Valley SWAT standoff in the county as well.
The Clackamas County Sheriff's Office maintains a dedicated public tip line at 503-723-4949 and a mobile app for residents to submit information on open felony investigations, per KGW-TV, with tips reviewed by investigators as they build the formal charge filing against Shunn.
