MS-13 gang member charged after teen's remains found on Long Island, officials say

A “self-admitted” MS-13 gang member with a violent criminal history was charged in the murder of a teen whose remains were found in New York a year after he was "viciously and barbarically" killed, officials said.

Carlos Benitez-Hernandez, 21, was arraigned Thursday on a second-degree murder charge in connection with the death of a teen, who authorities did not identify. Benitez-Hernandez was arrested Wednesday after authorities uncovered human remains in a shallow grave in East Meadow on Long Island.

The gang member was already in federal custody due to an immigration issue at the time of his arrest. U.S. Immigration and Customs Enforcement has not returned Fox News’s request for information.

WHAT IS MS-13, THE VIOLENT GANG TRUMP VOWED TO TARGET?

Nassau County Police Department Det. Lt. Stephen Fitzpatrick said in a Thursday news conference that authorities believe the motive for the killing is the “gang’s displeasure” with the teen’s actions.

“It’s more gang’s displeasure with his actions within the group, or it was something that they felt disrespectful to them or a threat to them,” Fitzpatrick said.

Benitez-Hernandez is believed to have killed the teen about a year ago by using a machete or cutting instruments to stab him multiple times — the usual violent techniques by MS-13 gang members, according to Fitzpatrick. The gang is also known to kill people in wooded areas.

Prosecutor Jared Rosenblatt said Benitez-Hernandez had “viciously and barbarically” attacked the teen, Newsday reported.

Fitzpatrick said Benitez-Hernandez has a “violent criminal history” that includes gang assault, weapons charges and victim intimidation. At the time of the teen’s death, Benitez-Hernandez was out on parole.

Authorities believe there are at least five MS-13 gang members linked to the slaying.

Benitez-Hernandez on Thursday pleaded not guilty to the murder charge, Newsday reported.
