A federal judge sentenced an MS-13 member Tuesday in Central Islip to 42 years in prison for luring two Long Island residents to secluded locations in Freeport and helping hack them to death. Kevin Cuevas Del Cid, 26, pleaded guilty last year to a related racketeering charge before U.S. District Judge Joan Azrack and also admitted his role in the hacking deaths of Kerin Pineda, 20, and Javier Castillo, 15. He had faced life in prison.
