Child hitman nicknamed Wolf Boy reveals how he tortured drug cartel rivals by cooking them alive and carried out first killing aged 12

A FORMER Mexican drugs cartel assassin known as Wolf Boy has revealed how he used to torture his rivals by “cooking them alive” but hated it when he got bloody.

The ruthless murderer performed his first hit when he was just 12 years old after taking part in an assassination boot camp.

After murdering 30 victims, he finally gave himself up to police after discovering his bosses had decided to kill him off too.

Wolf Boy lifts the lid on his horrific career for Channel 4’s new documentary series Meet the Drug Lords: Inside the Real Narcos

The show’s presenter-  ex Special Forces solider Jason Fox – comes face-to-face with the tattooed fiend in a high-security Texas jail.

Talking about his role as a torturer, he told the documentary: “I didn’t like that job, especially when it get so bloody.

“I’ve done the simple stuff that everyone starts doing, pulling teeth out, cutting fingers, start cooking them alive, it’s stuff that will get them to talk in a certain way.

“I didn’t enjoy it, but I tried to be the best at what I was doing. If I knew what I was going to do to survive in this life, this lifestyle, this world, I had to be the best.”

The programme sees former Royal Marine Commando and SBS veteran Fox investigate the billion dollar cartels and meet some of the kingpins who rule swathes of South America.

Fox  -who used to to hunt down drug lords  – returns to the continent to meet those he used to target.

He is given unprecedented access to the deadly Sinaloa Cartel run by the drug lord  ‘El Chapo’ who was extradited to the US in 2017.

He also visits a bizarre burial ground for some of the drug bosses slain in the cartel wars, with graves surrounded by lavish tombs, that resemble small houses and castles.

Many of the incredible graves – which cost up to £900,000 – are spread over two levels and feature large portraits of the murdered mobsters buried inside.

Several leading members of the infamous Sinaloa cartel are buried inside the Jarines del Humaya cemetery in Culiacan.

His graveyard guide tells him: “We have tombs here that are worth $700,000 US dollars, that’s a whole lot of money for just a grave, for just a tomb.

“Why do they have bullet proof glass, why do they have marble that comes from Italy, it is just crazy. Its a sign of power.

“They have so much money they don”t know where to spend that money.”

Meet the Drug Lords: Inside the Real Narcos is on Thursdays at 9pm on Channel 4.
