Peruvian police striving to stop the trafficking of migrants, drugs, and guns from neighboring Ecuador across the Zarumilla River live with the reality that the progress they make in daylight will likely evaporate after dark.

A team of seven officers make their way by truck to one of the spots favored by the gangs who specialize in the lucrative business of smuggling Venezuelan migrants into Peru.

The criminals throw up improvised spans made of wood, sandbags, rocks, cement, and tries near the international bridge and traders in contraband use the same corridors as the human traffickers.
