PRINCETON, Ind. (AP) – The sheriff of a southwestern Indiana county says a metal building that serves as an inmate work release center is saddling the county with high utility bills because it’s not properly insulated.

Gibson County Sheriff George Ballard told the county council the building’s utility bills are “way out of line” because it lacks a ceiling barrier to keep warm air from escaping through the roof.

County Commissioner Steve Bottoms says the building has “been a mess from the word ‘go.'”

The Princeton Daily Clarion reports (http://bit.ly/1igoMVG ) the work-release center opened in 2007 and houses about 80 work release beds that freed up 30 beds in the county’s jail.

The building’s opening ended a class-action lawsuit filed by the American Civil Liberties Union of Indiana over overcrowding at the jail.
