Four District men who pleaded guilty to being part of a downtown Washington street gang that targeted residents and businesses from Chinatown to Woodley Park to Bloomingdale, were sentenced Friday in D.C. Superior Court to up to nine years in prison.

Authorities said the gang called itself the “Show Out” crew, and members often teamed up and assaulted and robbed individuals who they deemed vulnerable because their victims were walking alone, talking on cellphones or homeless.

Police and prosecutors said the gang also engaged in flash mob-style robberies in which multiple members would flood into D.C. drugstores, convenience stores and gas stations and steal items. Authorities said other District neighborhoods that were targeted were NoMa, DuPont Circle and Metro Center.

Authorities said many of the members of the gang were also members of another crew made up primarily of gay and bisexual teenagers.

D.C. Superior Court Judge Lynn Leibovitz sentenced two of the members to nine years: Quayshawn L. Legget, 20, who prosecutors said was a leader of the gang, and James D. Matheny, 19. Ricardo J. Williams, 20, was sentenced to more than eight years, and Travis L. Morris, 21, was sentenced to more than six years.

Two other members of the gang, Bernard Trowell, 19, and Deandre M. Williams, 19, are scheduled to be sentenced May 24. All six men pleaded guilty to various assault and criminal street gang charges in February.
