NY1 has obtained video that shows the moment the notorious drug El Chapo landing in New York on a Mexican government plane. 

The shock in his eyes is apparent as he looks out the window while the top brass of federal law enforcement stood on the tarmac at Islip airport.

The extradition came as a surprise to New Yorkers, and even to the man responsible for getting him here. 

He didn't learn El Chapo was coming until earlier that day.

"It was a literally last minute conversation. ‘Get ready. He's coming,’" said Ray Donovan, the head of the Drug Enforcement Administration's New York Field Office.

Donovan has been the special agent-in-charge of the office since late last year. Before that, he headed the DEA's special operations division—which is tasked with capturing the most wanted drug fugitives.

There was healthy skepticism that El Chapo would face justice, because the last time he was captured by U.S. and Mexican law enforcement, El Chapo escaped from Mexico's most secure prison through a tunnel that led to his cell.

"We felt deflated, defeated. But we weren't, we weren't so defeated that we didn't think we can capture him again," said Donovan.

"We zeroed in on him up in the mountains up in, outside of Cosala, Mexico," he said. “The headquarters of the Sinaloa cartel in the remote mountains of Mexico's notorious "Golden Triangle.”

But they couldn’t just go and grab him. They had to do extensive surveillance.

"Now you know who the closest people are to Chapo, his inner circle, you can sort of paint that picture and say, 'Hey, this is his security people, this is the cook, these are the people that bring him supplies,' which in turn would lead to Chapo Guzman,” Donovan said.

And that it did in 2016. He was extradited to the U.S. a year later.  His case was prosecuted in Brooklyn federal court, because he's allegedly responsible for 80 percent of New York's heroin and cocaine supply.

"The biggest distribution point is New York City. Why? Because of the infrastructure," Donovan said. "There's a lot of airports, ports, highways. It's very easy for a Sinaloa cartel to bring their narcotics here and then disperse them all the way up to Maine, all the way down to West Virginia, Ohio, Baltimore."

The DEA says El Chapo is to blame for the explosion of the deadly synthetic drug Fentanyl, responsible for nearly half of the city’s overdose deaths last year.

"They were the first to mix heroin and fentanyl together, so to capture him and to have a verdict such as this is really a success story, not only to law enforcement, but to all the victims of overdose deaths across the nation,” Donovan said.

Donovan says El Chapo's conviction doesn’t signal the end of the Sinaloa cartel, because other family members have risen through the ranks. But he says the verdict sends a message, that they will be prosecuted, too.
