A federal judge today sentenced Edwn "Demente" Diaz, 20, to 35 years in federal prison for being one of several MS-13 members who stabbed Cristofer Perez de la Cruz, 16, of Chelsea so brutally the tips of their knives broke off in his skull - as another gang member fired repeated rounds into him.
Diaz and the others were hoping to gain a promotion in the gang by murdering somebody they thought was a member of the rival 18th Street Gang. They lured Perez de la Cruz to Falcon Street in East Boston through a fake girl's account on Facebook, prosecutors say.
Diaz pleaded guilty in May, after federal prosecutors presented evidence from surveillance tapes in which he boasted of slcing the teen like "onions:"
Not content with a murder where the victim was stabbed four dozen times and shot multiple times, Diaz stated, "I want to go back and get that son of a bitch again, and do something worse."
Diaz was one of 61 alleged MS-13 members arrested in raids in 2016. He is the 45th person to either plead or be found guilty.
