Police announced Tuesday that they had arrested one man and issued a warrant for another suspected of being involved in a weekend home invasion at U.S. Rep. Leonard Boswell's farm outside Lamoni.
The Iowa Department of Public Safety said authorities had arrested Cody John Rollins, 19, of Lamoni. He's charged with first degree burglary, assault while participating in a felony, going armed with intent and three counts of first degree robbery.
He was held on $50,000 bond, and a lawyer hadn't yet been named.
Police also were searching for David Palmer Dewberry, 20, of Fremont, Neb., who is considered armed and dangerous and may have fled the state.
Authorities have said a man with a gun entered the congressman's house Saturday night and attacked his daughter. Boswell tried to fight the man off, and as they scuffled, his 22-year-old grandson got a shotgun. When Boswell's grandson pointed the gun at the intruder, the man ran off.
Boswell, a 77-year-old Democrat, suffered minor injuries, but no one was seriously hurt.
Officials said Dewberry was the man who entered the house, while Rollins was his driver.
"They were looking for money," Decatur Country Sheriff Herbert Muir said at a news conference. "Within an hour of it happening, we had some names."
Dewberry and his family lived in Lamoni for a time before moving to Nebraska, and his mother was friendly with Boswell's wife and he had actually been to the Boswell home, Muir said. The gun used in the home invasion turned out to be a BB gun, but it resembled a pistol, he said.
FBI Special Agent Barry Ferguson said officials have interviewed Rollins but don't yet have the full story of what went on. They are continuing to investigate. He said the Boswells are well-liked in the community, and police quickly began receiving tips.
"It's obvious this community was outraged by this," Ferguson said. "Good people stepped forward with information."
Boswell issued a statement thanking police for their quick work.
"With today's new developments, I know my family and my neighbors around the farm will rest easier with a suspect identified and another individual already under arrest," Boswell said. "I have returned to my job in Washington and I am confident in the authorities handling the investigation back in Iowa."
Division of Criminal Investigation spokesman Mike Motsinger asked people to keep an eye out for Dewberry but not to approach him.
"Obviously, we need your assistance but we urge you not to try to approach this individual ... we do consider him armed and dangerous," he said.
Ferguson said the FBI likely would remain involved in the case because of the potential Dewberry crossed state lines in his flight.
Boswell's official residence is in Des Moines, where he moved after redistricting in 2000 tossed him into an overwhelmingly Republican district. However, he kept his farm about 60 miles south of Des Moines and visits often.
Boswell could well face another political scuffle this year after redistricting tossed Republican Reps. Steve King and Tom Latham into the same western Iowa district. Latham has announced plans to move to central Iowa and run against Boswell, who already announced his bid for re-election.
