The mayor of Fairfax, Va., a wealthy Washington suburb, was arrested on charges of distributing methamphetamines as part of a “sex for meth” operation, Fairfax County Police said Friday.

Two others identified as the mayor’s alleged suppliers were also arrested and charged with distributing methamphetamines, police said.

Mayor Richard “Scott” Silverthorne, 50, who is also a Fairfax county schools substitute teacher, was arrested Thursday after he allegedly provided meth to undercover officers who had met him at a local hotel, police said.

Silverthrone, who is serving his third term as mayor, was charged with felony distribution of meth and misdemeanor possession of drug paraphernalia. Silverthorne’s bio on the official Fairfax city website says he is  “a champion for quality of life issues.”

Officers then located and arrested his alleged suppliers, Juan Jose Fernandez, 34, and Caustin Lee McLauhglin, 21, of Maryland. Both were charged with felony charges of meth distribution.

Police said officers used a Taser on McLaughlin after he allegedly “physically resisted” his arrest.

Police said the arrests stemmed from an investigation that began in July when they learned of a possible meth dealer in Fairfax, about 20 miles west of Washington, D.C.  The investigation found that Silverthorne was allegedly trying to distribute meth through a website used to arrange for casual sex between men, police said.

An undercover detective then created a profile on the site and within a few days made contact with Silverthorne, police said. The two then made arrangements to meet at the Crowne Plaza Hotel in Virginia’s Tysons Corner area allegedly to exchange the meth for “a group sexual encounter,” police said.

Silverthorne official bio also says he “recognizes the importance of connecting communities. As Mayor, he strongly supports building more trails and sidewalks to encourage a more walkable, pedestrian-friendly community promoting a healthy lifestyle and cultivating a more livable city.”
