A Brooklyn federal judge sentenced an unrepentant MS-13 street gang member to 38 years in prison for murdering the wrong man in a 2006 Christmas Eve revenge killing in Flushing, Queens.

Hector Portillo, 20, pleaded guilty in September to standing over the body of Pashad Gray and firing bullet after bullet because he mistakenly thought Gray was a Bloods member who had previously stabbed him.

“Can me and my family get an apology?” Rynadia Whittingtondo, the victim’s sister, asked Judge Sterling Johnson.

“I gave him the opportunity, but he declined to speak,” said Johnson.
