Pernell Graham, a 42-year-old assistant principal at CIVICA Nevada Career & Collegiate Academy in North Las Vegas, has been arrested on suspicion of sexual assault with a minor. He is charged with six counts of assault on a child under 16 and several counts of first-degree kidnapping, child abuse/neglect with substantial bodily or mental harm, and two counts of school employee engaging in a sex act with a pupil. Because of Graham's involvement with youth, police believe there could be more victims.
