U.S. Marshals Stop Fugitive Sex Offender in His Tracks
Alexandria , VA - A two-time convicted sex offender on board a train bound for California had his flight from justice derailed by U.S. Marshals early today. William Hemphill (aka Andy), who turns 39 today, was arrested on an outstanding federal arrest warrant after three weeks on the run.

On Feb. 23, a federal arrest warrant was issued out of the Eastern District of Virginia, Alexandria Division, charging Hemphill with violating the terms of his supervised release. Hemphill was on court-ordered supervised release due to a 2006 conviction for possession of child pornography. U.S. Marshals began looking for Hemphill, who last reported his residence as a Motel 6 in Springfield, Virginia.

Thursday night, U.S. Marshals developed information that Hemphill was on board an Amtrak train that was headed for Emeryville, California, after boarding in Winter Park, Colorado. U.S. Marshals in Alexandria contacted the U.S. Marshals in Utah with this information, and a plan was established to intercept Hemphill on the train.

Undercover task force members of the U.S. Marshals Utah-based Violent Fugitive Apprehension Strike Team (VFAST) boarded the Amtrak train in Provo, Utah. While the train was traveling from Provo onto Salt Lake City, task force members positively identified Hemphill as a passenger on the train, but did not immediately take him into custody. Hemphill was observed asleep on the train.

Salt Lake City would be the end of the line for Hemphill, who was taken into custody without incident once the train stopped at the station around 2 a.m. today, with the assistance of Amtrak authorities. Hemphill remains in the custody of the U.S. Marshals in Salt Lake City.
