Police closed a portion of Highway 34 on Thursday evening (Oct. 28) after a standoff with an armed, delusional man who threatened residents at an RV park east of Waldport, Ore., the Lincoln County Sheriff’s Office told the Portland Oregonian.

Authorities evacuated residents at Chinook RV Park and a nearby business after initial negotiations with Abraham Jacob Manor, 23, of Waldport, failed.

Lincoln County Sheriff’s deputies responded to Chinook RV Park about 4:30 p.m. after Manor menaced a resident with a shotgun.

Manor, also a resident, retreated to his RV and refused to come out. Deputies determined he was irrational and armed with at least two weapons, the sheriff’s office said.

Police unsuccessfully negotiated with Manor for almost two hours before residents were evacuated. Oregon State Police and the SWAT Team were dispatched to continue negotiations over the phone.

Manor was still uncooperative, and police resorted to deploying tear gas to lure him out of his RV around 11 p.m.

Manor emerged and was arrested on charges of menacing, unlawful use of a weapon and disorderly conduct. He is being held on $75,000 bail at the Lincoln County Jail.
