Sherry Castro has filed a negligence lawsuit against Sparks Regional Medical Center accusing them of employing a food service worker who sexually assaulted her 6-year-old son while he was a patient in May 2005, a year after the employee was accused of molesting an elderly woman patient. In the 2005 incident, Campbell was initially charged with rape, but eventually he pleaded guilty to sexual indecency with a child and received a five-year suspended sentence.
