A leader of the Trece Loco Salvatrucha clique of MS-13 gang in the Boston area has been sentenced to serve 35 years in federal prison after he pleaded guilty to his part in killing a 16-year-old boy with machetes.

Jairo Perez, 27, is a Salvadoran national who went by the street name "Seco." He was sentenced Friday in U.S. District Court in Boston, prosecutors said.

Perez was convicted along with two other men, Edwin Gonzalez and Edwin Diaz, in the Jan. 10, 2016, murder of an East Boston boy the gang thought was a member of a rival organization.

The three men cornered the boy on a residential street in East Boston late at night and Perez, Diaz and Gonzalez struck him dozens of times with machetes, while a fourth gang member, Rigoberto Mejia, shot the boy with a firearm, prosecutors alleged in court documents.

Within days, the group had been betrayed by a cooperating witness and Perez was recorded admitting his part in the murder and telling the witness where he buried the murder weapons on Deer Island, where they were recovered by authorities.

Perez entered guilty pleas to charges under the RICO statutes in May 2018.

Following his initial sentence, Perez will be subject to five years of supervised release and deportation.
