Dandeny Muñoz Mosquera, better known as La Quica, was a sicario in the Medellín Cartel.
One of La Quica's first tasks was the assassination of Hermann Zapata; while killing him, he also killed a DEA Agent, Kevin Brady. Quica was arrested for these murders, but was able to make bail and returned to Colombia unpunished (Descenso).
In Colombia, he becomes one of the most prominent sicarios for Pablo Escobar. He's involved in the murders of all possible colaborators of DEA. He is in a personal competition with other sicario, Poison, for having the highest number of murders.
La Quica finds several young boys that are recluted for Pablo's army, and he's choses the boy that explodes a bomb in a plane, killing more than 100 people, in the attemp of killing the president of Colombia.
Later, La Quica recluites Limon, a pimp and taxi driver in Medellin, who helps Pablo to move around the city. One of the prostitutes working with Limon calls the police and La Quica is allmost captured, in revenge, he kills all the prostitutes and tries to kill Maritza, a friend of Limon who was involved. Limon and Quica search for her, but Limon is trying to help her at the same time. Finally she´s saved.
Quica is one of the last loyal men to Pablo, even that he´s afraid, mostly becouse he knows that they are defeated. He´s betrayed by Blackie, and tries to escape; killing other of Escobar´s men, but is finally captured by the police.
Quica is interrogated by the DEA and accepts to help them, giving the location of Escobar´s last soldiers and calling Pablo, but Pablo knows that he´s with police and avoids being captured or killed that night.
