Santiago Gallon Henao was a Colombian drug trafficker and a leader of the Gallon gang.
In 1993, Judy Moncada and Don Berna met with Santiago and his brother Pedro and convinced them to cut ties with Pablo Escobar's Medellín cartel and join Los Pepes instead.
In 1994, after footballer Andres Escobar's self-goal resulted in Colombia's elimination from the World Cup, Santiago had Andres killed.
