Somewhat story related and aquired by taking down the boss The Beauty Queen. To get to her you need take out some or all of her underbosses; El Cerebro, Boston Reed, El Pulpo, Antonio, El Gato and El Boquita. This is done by completing the main missions in each area marked with a yellow arrow followed by a yellow crown. To unlock the main missions you need to find all the yellow main mission intel folders throughout the region map.
