Beverly Campbell is Pitkin County's Jail Administrative Officer. We've learned ... on Monday, Campbell insinuated herself in the deal her boss -- the Sheriff himself -- signed off on. Campbell believes Charlie is not eligible for work release, but rather his daily get-out-of-jail pass should be something called "Useful Public Service (UPS)."
We're told Campbell believes under UPS, Charlie should only get out between the hours of 10 AM and 4 PM. Under the work release deal her boss signed, Charlie was supposed to get out between 8 AM and 8 PM.
Even worse, sources say Campbell believes under the UPS program Charlie has no right to eat, drink sodas, or smoke when he's working at the Aspen Theatre.
And, under the UPS program, Charlie would have faced a longer period of probation after serving his time than under the work release program.
TMZ broke the story ... the Sheriff and the D.A. actually signed a plea deal that utterly contradicted what Campbell was demanding, but the Sheriff would not overrule or discipline her ... at least not while he was in court.
In the end, we're told Charlie's lawyer, Yale Galanter, refused to relent and pulled the plug.
Will the Sheriff lay down the law to Beverly?
