(Olympia, WA)  --  A Washington State Department of Corrections computer specialist says he was made a scapegoat for the fact that a computer error wasn't fixed for more than two years after it was discovered, leading to inmates being released before their sentences ended.  David Dunnington told a Senate committee yesterday that investigators for Governor Jay Inslee targeted him unfairly for the delay.  Dunnington, who was demoted after the investigation was completed, told the panel that many people were responsible for working to correct the computer problem but that he was targeted because he was an information technology manager for DOC.  The Senate Law and Justice Committee is conducting its own investigation into the computer glitch that led to more than three-thousand inmates being improperly released early from Washington prisons.
