BOSTON – An MS-13 member pleaded guilty today in federal court in Boston to illegal possession of firearms and ammunition.

Elmer Alfaro Hercules, 20, a Salvadoran national, pleaded guilty to one count of being an illegal alien in possession of firearms and ammunition. Hercules was indicted in June 2018. U.S. District Court Judge F. Dennis Saylor IV scheduled sentencing for Jan. 17, 2019.

On May 22, 2018, Hercules was arrested in possession of a loaded firearm in an East Boston park, a location where numerous MS-13 gang members have been observed and where gang-on-gang violence frequently occurs. Hercules unlawfully entered the United States in 2014 as an unaccompanied minor. In April 2015, an immigration judge ordered him deported in absentia.

The charge of being an alien in possession of a firearm and ammunition provides for a sentence of no greater than 10 years in prison, three years of supervised release, and a fine of $250,000. Hercules will also face deportation proceedings upon completion of his sentence. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors.
