The punishment phase has begun in the trial of a former Brownsboro teacher accused of having sex with a student. Just before 6:00 p.m., a guilty verdict was read against Donald Dudley, 43. Dudley had sex with a 16-year-old student while he was teaching at Brownsboro High School. Following the verdict, Judge Cynthia Stephens Kent increased Dudley's bond to $600,000. The punishment phase is expected to wrap up tomorrow. Dudley faces up to 20 years in prison. Other charges involving the same student are pending in Henderson County.
