FALN was an organization that sought Puerto Rican independence through a wave of terror more in the 1970s.
More than 130 bombings in New York, Illinois and Puerto Rico were attributed to the group, including at least 28 in Chicago. Five people were killed, and 84 were injured, including four police officers.
Between 1975 and 1979, FALN took credit for or was suspected in bomb attacks at the Merchandise Mart, the Chicago Police Department headquarters, Woodfield Shopping Center and a former Marshall Field's department store, among others.
In March 1980, gun-toting sympathizers stormed the Carter-Mondale presidential campaign office in Chicago and held campaign workers hostage.
But a month later, FALN suffered its most severe setback when 11 members were arrested in a stolen truck in Evanston.
