MANILA, Utah — Three people have pleaded guilty in a case of illegal voter registration in eastern Utah's Daggett County.

Fifty-one people have been accused of illegally registering in Daggett, a misdemeanor, even though they don't live there.

The case involves the 2006 election, when then-Sheriff Alan Campbell complained that the voter rolls were growing in the small county near the Wyoming border.

Fourteen people listed the address of the parents of sheriff candidate Rick Ellsworth. He defeated Campbell by 20 votes.

The Salt Lake Tribune says three people pleaded guilty to a lesser charge Friday and were fined $500. They are Zachary B. Millett of Roosevelt, and Wyoming residents Brandon C. Ellsworth and Charles C. Rich.

Six other people also pleaded guilty to a lesser charge, but their records will be wiped clean in a year if they avoid trouble. They signed up but didn't vote in Daggett County.
