Additional suspect wanted in gang-related murder of Virginia man

MONTGOMERY COUNTY, Md. - Investigators believe many of the suspects have connections to the street gang Mara Salvatrucha, commonly known as MS-13.

Prince William County police say the murder may be the result of an internal power struggle within MS-13. It appears likely Sosa Rivas claimed a role in the gang that wasn't his. They say their murder investigation indicates gang members weren't happy that Sosa Rivas claimed to be the leader of MS-13 in that area, but police also indicate there could be other factors in his murder.
