Pablo Escobar that some individual Search Bloc members directly participated in missions of "Los Pepes" death squads. One of the leaders of "Los Pepes" was Diego Murillo Bejarano (also known as "Don Berna"), a former Medellín Cartel associate who became a rival drug kingpin and eventually emerged as a leader of one of the most powerful factions within the Self-Defence of Colombia. In March 1976, the 26-year-old Escobar married Maria Victoria Henao, who was 15. The relationship was discouraged by the Henao family, who considered Escobar socially inferior; the pair eloped. They had two children: Juan Pablo (now Sebastián Marroquín) and Manuela.
Pablo Escobar joined the manhunt for Escobar. They trained and advised a special Colombian police task force known as the Search Bloc, which had been created to locate Escobar. Later, as the conflict between Escobar and the governments of the United States and Colombia dragged on, and as the numbers of Escobar's enemies grew, a vigilante group known as "Los Pepes" (Los Perseguidos por Pablo Escobar, "People Persecuted by Pablo Escobar") was formed. The group was financed by his rivals and former associates, including the Cali Cartel and right-wing paramilitaries led by Carlos Castaño, who would later fund the Peasant Self-Defense Forces
