The FBI said Wednesday that Juan Elias Garcia is the last of four MS-13 gang members being sought in the 2010 killings of Vanessa Argueta and her son Diego Torres on Long Island. Authorities say Argueta had ties to rival gangs which threated Garcia.
Authorities say Garcia and other MS-13 members got permission from the gang's leader to take Argueta and her son into the woods and shoot them.
Garcia is from El Salvador but also has ties to Nicaragua, Honduras, Guatemala and Panama.
Authorities announced a $100,000 reward for information leading to his arrest.
