Pablo Escobar was trapped. The murderous drug cartel lord, and one lone bodyguard, were holed up in a Medellin, Colombia, house, and the Bloque de Busqueda or “Search Bloc”— special operation units of the country’s national police — were closing in.

Javier Pena and Stephen Murphy, retired U.S. Drug Enforcement Agency agents, and consultants and inspiration for the Netflix show, “Narcos,” told Escobar’s sordid story, and their parts in his demise, during the Tuesday afternoon General Session.

“Pablo grew up poor in Medellin,” Pena said. “He started experimenting [with selling] one, two kilos of cocaine. Before it was all over, Pablo Escobar was producing and sending 80% of the cocaine that was reaching the world. … We called him the inventor of narcoterrorism.” At any time, Escobar had 40 to 50 tons of cocaine ready to sell. During Escobar’s heyday, Forbes ranked him the seventh-richest person in the world, Murphy said, with estimated total worth of $8 billion to $30 billion.

For much of his life, Bill Browder’s goal was simple: to be the most successful capitalist in Eastern Europe. And he reached his goal there and in Russia. He made fortunes and lost them and then made them again. But that all changed in 2009 when his lawyer and friend, Sergei Magnitsky, died in prison under suspicious circumstances one month after submitting detailed documentation of a governmental scandal to Russian investigators. The year before, Magnitsky had exposed a complicated $230 million web of tax-refund fraud and graft involving Russian government officials. And for his courageous efforts, he lost his life.
