FAIRFAX, Va. — Richard “Scott” Silverthorne, 50, the Mayor of Fairfax, Virginia was arrested and charged with dealing methamphetamine.

A tip to police in late July prompted the investigation.

“Based on information obtained during the investigation, a suspect was identified who was allegedly distributing methamphetamine through a website used to arrange for casual sexual encounters between men,” a Fairfax Police spokesman said. “An undercover detective created a profile on this website and within a few days, the suspect made contact through the website.”

During their online conversation, the suspect and undercover officer agreed to meet and exchange sex for drugs.

“The suspect arranged to bring methamphetamine along with other men to the engagement,” police said. “On Thursday, August 4, the Street Crimes Unit met the suspect at the Crowne Plaza Hotel in Tysons Corner.”

Police identified the suspect as Silverthorne.

“Silverthorne provided methamphetamine to the undercover detectives and was subsequently arrested and charged with felony distribution of methamphetamine and misdemeanor possession of drug paraphernalia,” police said.

In addition to his role as Mayor of Fairfax, he is also a substitute teacher for the Fairfax County Public Schools.

Detectives also arrested Silverthorne’s alleged suppliers; 34-year-old Juan Jose Fernandez and 21-year-old Caustin Lee McLaughlin.
