LEADVILLE — A former Colorado undersheriff has been arrested following a grand jury indictment on charges stemming from the alleged harassment of several 911 dispatchers and the alleged exploitation of a minor. Former Lake County undersheriff Fernando Mendoza was arrested Tuesday and is being held without bond. District Attorney Bruce Brown told Denver's KMGH-TV that Mendoza asked the minor to send him nude photos and used a camera taken from the sheriff's office to watch her undressing. Brown said Mendoza is also charged with two counts of second-degree official misconduct in connection with the sexual harassment allegations. Mendoza was fired from the department several weeks ago.
