The prosecution this year of more than 60 local members or associates of the international gang MS-13 has shed light on how the gang, and a rival gang, operate. So far, 26 defendants have pleaded guilty to racketeering, drug trafficking and weapons offenses and the only defendant to go to trial has been convicted.
But even the limited discussion of evidence has revealed the extreme violence gang members have employed in Chelsea, Everett, East Boston, Lynn and Revere.
WBUR's David Boeri has been covering the prosecution of the gang and its rival gang here in Massachusetts, and talked about it on Morning Edition.
