A joint investigation by the Switzerland County Sheriff’s Office and Vevay Police Department has netted a third arrest for attempting to use online social media to solicit sex with a minor.

Brandon W. Mardis, 26, of Williamstown, Kentucky, was arrested on charges of attempted sexual misconduct with a minor, a Level 4 felony, and dissemination of matter harmful to a minor, a Level 5 felony. Mardis’ arrest came at the conclusion of a joint investigation that also led to the arrest of a Madison man and a Bennington man on similar charges.

Switzerland County Sheriff Brian L. Morton earlier said that his department and Vevay Police, like a lot of others, conduct ongoing computer crimes investigations to identify suspects seeking to contact underage individuals through social media for illegal purposes. The three arrests were all from that investigation.

The sexual misconduct charge against Mardis involves arranging to have sexual contact with a minor and traveling to meet the minor.

Police had previously charged Jack D. Shelley, 48, of Madison, on two counts of child solicitation, and two counts of dissemination of matter harmful to a minor, and Harry L. Waller, 58, of Bennington with attempted sexual misconduct with a minor, and dissemination of matter harmful to a minor.
