In the decades they spent at the DEA, Javier Peña and Steve Murphy risked their lives hunting large and small drug traffickers. But their biggest challenge was the hunt for Pablo Escobar in Colombia. The partners, who began their careers as small-town cops, have been immortalised in Netflix's 'Narcos', a fictional account of their hunt for Escobar. Now, for the first time ever, they tell the real story of how they brought down the world's first narco-terrorist, the challenges they faced, and the innovative strategies they employed to successfully end the reign of terror of the world's most wanted criminal.
