In 1990, one of its more prominent figures, presidential candidate and former guerrilla commander Carlos Pizarro Leongómez, while aboard an airline flight, was murdered by assassins, supposedly on the orders of drug cartel and paramilitary leaders (disappeared AUC commander Carlos Castaño publicly admitted his own responsibility for the murder in a 2002 book and interviews). Some of its other members were also subject to multiple threats or likewise murdered. Antonio Navarro Wolff replaced the deceased Pizarro as candidate and leader of the party, finishing third in that year's presidential race. Despite the continuation of smaller scale violence against it, the AD/M-19 survived through the 1990s, achieved favorable electoral results on a local level and actively participated as a high-profile political force in the forging of Colombia's modern 1991 constitution, which replaced a conservative document ostensibly dating from 1886. Antonio Navarro was one of the three co-presidents of the Constituent Assembly of Colombia, together with representatives from the Colombian Liberal Party and the Colombian Conservative Party. Several analysts consider that the AD/M-19 reached its peak at this point in time and, while never disappearing completely from the political background, it began to gradually decline as a party on its own, although many of its ex-members have gained influence in the Independent Democratic Pole coalition.
