Nuevo Laredo is one of the most feared cartel cities in Mexico, a place where disappearances, gun battles, and corruption became part of daily life as the Cartel del Noreste, or CDN, tightened its grip on the border. Born from the remnants of the brutal Zetas organization, CDN turned the city into a battlefield, fighting for control of smuggling routes into Texas while allegedly terrorizing civilians, journalists, and anyone seen as a threat. The city became so cartel-corrupted that it dismantled its own police force entirely.

The documentary film Spring of the Vanishing adds another layer to the story, documenting how U.S.-trained Mexican marines deployed to fight the Zetas instead carried out their own wave of kidnappings and killings of civilians. Director Andrew Glazer pulls back the curtain on a city where families still search for missing loved ones, and where the line between organized crime and the state itself often seems impossible to separate.

Meet the Stopwatch Gang: three polite Canadian crooks turned bank robbery into a precision sport, hitting over 140 banks across North America and walking away with $15 million without firing a single shot. They wore presidential Halloween masks, escaped from prison multiple times, and became so notorious that the boss landed on the FBI's Most Wanted list. At their peak, they stole millions while humiliating police forces across North America and becoming legends in the criminal underworld.

Vassilis Paleokostas, and his big brother Nikos, grew up shoeless in a Greek mountain village. When the boys moved to a city, they discovered a talent for robbery — and honed it with a mysterious criminal known locally as The Artist.

Before long, the trio were pulling off some of the most daring heists in European history. At a volatile time of financial crashes, leftwing guerrillas and political corruption, the brothers dove into a new gig: kidnapping billionaire business magnates.

What confounded cops the most was how Vassilis Paleokostas distributed his loot among the poor, and how the Greek people loved him for it. If authorities did catch up with the country’s Robin Hood, there wasn’t a prison in the land that could hold him for long. Cue decades of capers that could keep a Hollywood writers’ room busy for months.

When Mexican special forces killed El Mencho in February 2026, the throne of Mexico's most powerful cartel was up for grabs. But there's one man who many assumed would be taking over: Juan Carlos Valencia González, a 41-year-old California-born dual citizen known as "El 03," the stepson of the slain narco boss.

His cartel royalty bloodline is almost absurdly stacked, as his mother, Rosalinda González Valencia, dubbed "La Jefa," was El Mencho's wife and a key financial architect of the cartel's money laundering empire, while his uncles from the González Valencia clan were systematically arrested and extradited to the U.S. over the past decade. And his father just happened to be the founder of CJNG's predecessor, the Milenio Cartel.

Now an American citizen effectively runs a terrorist-designated drug empire responsible for flooding the U.S. with fentanyl, creating a legal nightmare for U.S. intelligence agencies with limited tools to go after one of their own.

When Paraguay extradited French-Corsican heroin kingpin Auguste Ricord to the US in 1972, some thought Paraguay’s narco trafficking days might be numbered. If anything they were just beginning. Within years the tiny nation had welcomed Hong Kong Triads and Lebanese militants — who, combined with considerable homegrown narco and cigarette trafficking, made Paraguay one of the world’s most lawless places, a hive of narco-contraband-terror madness.

This nexus was focused not on the country’s sleepy capital city Asunción, but the so-called “Triple Frontier”, where Paraguay, Argentina and Brazil met. And thanks to a 2018 conspiracy involving a local trafficker, a money mule and an up-and-coming senator, we know it’s very much alive and kicking today.
