Special Agent David LeValley headed the criminal division of the Federal Bureau of Investigation's (FBI) Washington office until last November 8. While in office, he witnessed the rise of the MS13, the Barrio 18 (18th Street) and other smaller gangs in the District of Columbia as well as in parts of Maryland and Virginia, all host to tens of thousands of Central American immigrants. In early 2016, he participated in the investigation, which led to the sentencing of half a dozen MS13 members from the "Sailors Loco" clique in Virginia. Among the charges for sentencing were eight counts of homicide. Currently on the verge of retirement, LeValley believes that the Salvadoran gang has entered a new expansion phase along the East Coast of the United States.
