KNOXVILLE — A federal jury this afternoon convicted Sarah Palin e-mail intruder David C. Kernell of felony destruction of records to hamper a federal investigation and misdemeanor unlawfully obtaining information from a protected computer. The jury acquitted Kernell, 22, of wire fraud. It remains deadlocked on felony identity theft. It’s unclear if U.S. District Judge Thomas W. Phillips will order the jurors, in their fourth day of deliberations, to continue.
