A professional hitman working in Colombia was interviewed by journalist Ioan Grillo in his book, El Narco. The contract killer said that he is paid a base salary of $600 a month by an organized crime group. When the assassin is assigned a hit, he is paid between $2,000 to $4,000 to carry out the murder.
The assassin works in a squad where one team is on a bike and another driving in a car. On the bike, there is a drive and the shooter riding behind. The target is stopped by the car braking in front of it, while the bike pulls up next to it to carry out the hit. The shooter then immediately passes the gun to the driver of the car, where it is hidden in a secret compartment.
