“Please be proactive as Mr. Slye is described as a computer genius and while today he lurks under ‘Nicole Grace Smith’, tomorrow it could be another alias,” the statement continued.

Police said detectives spoke to Slye on October 23 and he admitted to using the alias to obtain pictures and to contacting wrestlers at Windham High School.
