RIO, Wis. (AP) -- At least a dozen federal and local law enforcement agents are surrounding a Columbia County home today.
They're doing so after the couple who lived there was charged with filing false liens.
Sherry Duval is a spokeswoman for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives.
She says her agency is helping the Columbia County Sheriff's Office serve a state warrant.
Columbia County SWAT team members and other investigators are milling about a log cabin, barn and other dilapidated buildings on the wooded property about 30 moles northeast of Madison.
Crime scene tape stretches around the property.
The Columbia County Sheriff's Department chief deputy, Mike Babcock, told WISC-TV that the home in Rio once belonged to 64-year-old Lester Sundsmo and his 56-year-old wife, Lilac.
But the county took it over after they failed to pay taxes.
Babcock says the Sundsmos were taken into custody today during a traffic stop.
Wisconsin Attorney General J.B. Van Hollen says they're charged with five felony counts each of criminal slander of title.
A telephone message left at the home today was not immediately returned.
