Douglas County Sheriff Tim Dunning has launched his bid for re-election in 2014.

Dunning, who was first elected sheriff of Nebraska's most populous county in 1994, filed for re-election this week with the Douglas County Elections Office.

In announcing his campaign, Dunning said his office has never been over budget during his tenure and that he has held spending growth to less than 6 percent from 2009 through 2013. He noted that he also oversaw expansion of the county's crime lab, paid for with money seized from drug crimes, and has the only nationally accredited sheriff's department in the state.

His campaign reports raising $43,000 in 2013, and he has more than $35,000 cash on hand.

So far, Dunning is running unopposed. The filing deadline for challengers is March 3.
