Alleged trafficker Zhi Dong Zhang escaped via a tunnel in Mexico before flying to Cuba and reportedly Russia but now finds himself on trial in a Brooklyn courtroom

The China-Mexico fentanyl pipeline: increasingly sophisticated and deadly

Like so many great escapes, it involved a tunnel.

One night in July, in the Mexico City neighbourhood where he was under house arrest, Zhi Dong Zhang snuck through a hole into the property nextdoor and escaped from under the noses of the soldiers guarding him.

Zhang, an alleged drug trafficker, managed to get to Cuba and then reportedly all the way to Russia – only to be turned back. At the end of October, the Cuban government announced that it had arrested him. The same day he was flown back to Mexico and extradited straight to the US.
