The attorney for a teen charged with murder in a car accident that killed two people argued in court Monday a motion to dismiss the charges on the basis that the district attorney’s office had “selectively prosecuted” his client because of his age and the law enforcement connections of the victim’s family. In what the judge deemed an “unusual case,” 17-year-old Christopher Eggersdorf is being charged with felony murder in Hall County Superior Court. Larry Duttweiler, senior assistant public defender for the Northeastern Judicial Circuit, said the more typical charge of vehicular homicide — a misdemeanor or felony depending on the level of “recklessness” — is the maximum charge his client should face.
