The widow of a slain Dickson County deputy has confirmed that a special prosecutor has been named to review the investigation into her husband’s death. Brandi Bellar said she is “cautiously optimistic” after being notified Wednesday afternoon that District Attorney Randy York of Cookeville has been appointed by the Tennessee District Attorneys General Conference to look into allegations that other law enforcement officers “taunted and bullied” the man who shot and killed Deputy Keith Bellar in June 2011. Bellar says she has been told by other law enforcement officers that taunting text messages were sent by at least two other officers to Jayson Eggenberg, claiming to be having a sexual relationship with his estranged wife and she is concerned that those actions might have triggered his assault on his wife during which Deputy Bellar was shot. Bellar said she first heard the news from a Nashville reporter who detailed her concerns before being officially notified by Assistant District Attorney Ray Crouch. Bellar said she is cautious because she wants to make sure the special prosecutor is independent of District Attorney Dan Alsobrooks’ office and the appointment is not “just a continuation of the good ole boy network.” Alsobrooks at first declined to seek a special prosecutor but reportedly asked for the appointment after a request by Dickson Police Chief Rick Chandler and Sheriff Jeff Bledsoe. “It’s been an uphill battle to get anything other than lip service,” Bellar said of her efforts, adding that more people have come forward with evidence since she went public. Bellar said Wednesday afternoon that she has not been contacted by York. Alsobrooks was not immediately available for comment.
