SEATTLE (AP) - An insane killer who slipped away from the staff of a mental institution on a field trip to the Spokane County International Fair was recaptured Sunday without injury more than 220 miles away in south-central Washington state.

With a helicopter overhead and dozens of federal, state and local law enforcement officers swarming around Goldendale, Phillip Arnold Paul seemed ready to surrender when he walked out to the Goldendale-Bickleton road about 22 miles east of town shortly after 4 p.m., just as search personnel arrived at the scene, Klickitat County Sheriff Rick McComas told The Associated Press.

Spokane County sheriff's Capt. Dave Reagan said Paul, 47, was preparing to hitchhike, but McComas said Paul offered no resistance.

"It appeared that he was going to voluntarily turn himself in because of the pressure of the ground force we had in the area," McComas said. "He chose not to stay hidden any longer.

"He came out of the brush, onto the roadway, as law enforcement officers were going by. His intent was to voluntarily give himself up because he knew we were going to find him."

The sheriff said he didn't know how Paul reached the area, adding the information that he might be nearby came from Spokane.

Reagan said the arrest was made by Spokane County Detective Roger W. Knight, who also nabbed Paul after he gave Eastern State

Hospital personnel the slip during a field trip in Medical Lake, where the mental institution is located, in 1991. Following that arrest, Paul knocked Knight unconscious in the jail booking area, separating his shoulder, and was convicted of first-degree escape and second-degree assault.

McComas said Paul would be taken to Yakima following a brief checkup by medics in Goldendale.
