Founder Of Notorious Street Gang 'MS-13' Sent To Prison

Carlos Geovanni Martinez-Aguilar, of Mesquite, Texas, was sentenced on Tuesday by a US District Court judge in Boston to three years in prison followed by two years of probation.

Martinez-Aguilar pleaded guilty in April to unlawful re-entry of a deported alien.

Prosecutors say Martinez-Aguilar, a native of El Salvador, illegally entered the US in 1995. In 2002, he was convicted of unarmed robbery. He was deported in July 2003.

Prior to his deportation, Martinez-Aguilar was a leader of the MS-13 gang in the North Shore area of Massachusetts.

Authorities say MS-13, or Mara Salvatrucha, has origins in El Salvador. It is notorious for using extreme violence.
