Fentanyl is blamed for about 70,000 overdose deaths per year in the United States.

“We allege El Nini was one of the Sinaloa Cartel’s lead sicarios, or assassins, and was responsible for the murder, torture, and kidnapping of rivals and witnesses who threatened the cartel’s criminal drug trafficking enterprise,� U.S. Attorney General Merrick Garland said in a news release Saturday.

Court records did not list an attorney for Pérez Salas who might comment on his behalf.

The Justice Department last year announced a slew of charges against cartel leaders, and the posted a $3 million reward for the capture of Pérez Salas, 31. He was captured at a walled property in the Sinaloa state capital of Culiacan last November.

In a written statement, President Joe Biden thanked Mexican President Andrés Manuel López Obrador for extraditing Pérez Salas.

“Our governments will continue to work together to attack the fentanyl and synthetic drug epidemic that is killing so many people in our homelands and globally, and to bring to justice the criminals and organizations producing, smuggling, and selling these lethal poisons in both of our countries,� Biden said.

The nickname Nini is apparently a reference to a Mexican slang saying “neither nor,� used to describe youths who neither work nor study.

At the time of his arrest, Mike Vigil, former head of international operations for the U.S Drug Enforcement Administration, called him “a complete psychopath.�

Pérez Salas commanded a security team known as the Ninis, “a particularly violent group of security personnel for the Chapitos,� according to an indictment unsealed last year in New York. The Ninis “received military-style training in multiple areas of combat, including urban warfare, special weapons and tactics, and sniper proficiency.�

Pérez Salas participated in the torture of a Mexican federal agent in 2017, authorities said. He and others allegedly tortured the man for two hours, inserting a corkscrew into his muscles, ripping it out and placing hot chiles in the wounds.

According to the indictment, the Ninis carried out gruesome acts of violence.

The Ninis would take captured rivals to ranches owned by the Chapitos for execution, with some victims fed — dead or alive — to tigers the Chapitos raised as pets, the indictment said.
