The arrest ends a national manhunt for the pair, accused of shooting at law enforcement officers in Wilmington in February.
Chevie Kehoe, 24, was arrested about noon by ATF, FBI and state and local authorities in Cedar City, Utah, about 220 miles southwest of Salt Lake City.
He was taken into custody without incident and will be transported to Salt Lake City for an initial appearance before a U.S. magistrate, according to FBI spokesman Thomas T. Kubic.
Investigators said Chevie Kehoe, who also faces federal
firearms charges, had been working on a small ranch in southwest Utah.
The daughter of the rancher said both brothers and their families had been living on the ranch.
``Dad found them in the hills hungry. He could see they didn't have food. They had some little kids that were going hungry,'' said the daughter of Rodney Leavitt, who lives near Gunlock, 37 miles southwest of Cedar City. She asked that her name not be used.
``We're still just reeling in shock. For all we knew, they were just two young families that were down on their luck,'' she said.
Leavitt's daughter said the men and their families had been living in a trailer on 200 acres Leavitt owns near the tiny town of Beryl, about 35 miles northwest of Cedar City.
Both Kehoe brothers face indictment in Ohio on 16 counts, including attempted murder of a police officer. They also face federal charges of fleeing to avoid prosecution. Chevie Kehoe is also wanted for questioning in connection with the 1996 slayings of an Arkansas gun dealer, his wife and her daughter.
In Spokane, Cheyne Kehoe, 21, appeared Tuesday afternoon in a Washington state court, and was ordered held on $1 million bail on a warrant for unlawful flight to avoid prosecution.
Cheyne Kehoe said little during the hearing except "Yes ma'am," or "no ma'am," to the judge's questions.
Spokane County District Court Commissioner Virginia Rockwood indicated that Cheyne Kehoe does not intend to sign a waiver to return to Ohio voluntarily and she set another hearing for July 16 to make sure Ohio signs a governor's warrant for his extradition.
She said the state of Washington can keep Cheyne Kehoe on the fugitive warrant for 90 days.
Rockwood asked how long Cheyne Kehoe had been back in Washington and he said "Since 6 a.m. yesterday morning. I turned myself in immediately."
Clinton County Assistant Prosecutor Rick Moyer, who is handling Cheyne Kehoe's extradition to Ohio, said, `We are following through with the appropriate paperwork to have him extradited.''
Moyer said Clinton County would ask that Cheyne Kehoe's bond be set high enough to keep him in custody. `Our position is he's a flight risk,'' he said.
Cheyne Kehoe can agree to return to Wilmington to face charges or fight extradition. Should he fight extradition, Moyer said, a complaint will be filed with the governors of both Ohio and Washington. If that happens, Cheyne Kehoe could be extradited to Ohio within 60 days, Moyer said.
If he doesn't fight extradition, Cheyne Kehoe could be returned to Ohio within days.
Assistant U.S. Attorney Jim Crum in Spokane said federal authorities would defer to Ohio authorities before seeking Chevie Kehoe's return to face firearms charges in Washington.
"We're going to defer to the prosecutors back in Ohio, and after that's done, we'll make a decision on what to do," Crum said.
Chevie Kehoe was also sought for questioning in the slayings of Tilly, Ark. gun dealer David Mueller, 52; his wife, Nancy, 28; and her daughter, Sarah Elizabeth Powell, 8. The three disappeared in January 1996. Their decomposed bodies were dredged from the Illinois Bayou near Russellville, Ark. on June 28.
Stevens County Undersheriff Gilbert Geer said Cheyne Kehoe was in custody for an hour Monday before he was sent to the Spokane County Jail, 80 miles from Colville.
`He was thin, but he looked healthy,'' Geer said.
Cheyne Kehoe didn't say where he had been, Geer said. `He's not talking.''
When Cheyne Kehoe surrendered, he was accompanied by his wife's parents, Bob and Ronda Wilburn of Colville.
Bob Wilburn said in an interview with the Spokane Spokesman-Review that his faith in his son-in-law is unshaken.
`He's a good, hard-working, honest young man,' Wilburn said. `I was just tickled to death when he married my daughter.'
Wilburn said he disbelieves the much-broadcast videotape that police say shows Cheyne Kehoe opening fire on an Ohio State Patrol trooper after a traffic stop. Wilburn contends the videotape, recorded from the cruiser, was edited to give a false impression.
Wilburn said the brothers separated before Cheyne Kehoe turned up at Wilburn's home about 6 a.m. Monday. He said he doesn't know the circumstances and doesn't want to know.
`All I care about is Cheyne is safe and, hopefully, we'll get these charges dropped,' Wilburn said. He credited his son-in-law with
`a hell of a courageous act' in returning to Colville to surrender.
Wilburn said Cheyne Kehoe wanted his son and wife, Tana, safe with her parents before he turned himself in.
The Kehoe brothers came to national attention following a Feb. 15 shoot-out in Wilmington when an Ohio Highway Patrol trooper and a Clinton County sheriff's deputy stopped a Chevrolet Suburban to question its driver about expired tags.
The cruiser camera recorded the passenger jumping from the car and firing at the officers. The driver and passenger then fled, one driving away in the Suburban and the other on foot.
Minutes later, a second confrontation took place when a Wilmington police officer spotted the Suburban in a parking lot. The police cruiser's windshield was shattered when the driver fired at the officer and then fled on foot.
