A reputed MS-13 gang member was arraigned on a murder charge Thursday, making him the sixth and final member of the notorious gang busted in the 2017 machete slaying of a suspected snitch on Long Island.

Luis Alejandro Varela, 21 — nicknamed “Felon” — is accused of taking part in the brutal slaying of Carlos Rivas-Majano, 22, who was lured into some woods near the Meadowbrook Parkway and hacked to death in August 2017, Nassau County officials said Thursday.

“We had issued a warrant for him. When he showed up in federal plaza applying for US citizenship, the warrant popped and we arrested him,” Nassau Police Detective Lt. Stephen Fitzpatrick said.

Majano’s dismembered body was found a year later in a hole in the woods near Kellenberg High School in Uniondale.

Several of the gang members arrested in the slaying were illegal immigrants, although Varela’s exact status is uncertain for now. The violent MS-13 gang has terrorized Long Island communities for years.

“The facts of this case, like every MS-13 homicide, are horrific and the arrest this morning of this individual makes our community safer,” Nassau County District Attorney Madeline Singas said at a press conference Thursday.
