2. The Sinaloa group’s origins
The Sinaloa group has its origins in the state of Sinaloa, on Mexico’s northwest Pacific coast. From the 1970s, the state was a key area for moving Colombian cocaine and other contraband, as well as for the cultivation of marijuana and poppy. The drug-trafficking network evolved from a group of rural families, who over the decades have formed alliances with groups in various parts of the country.
