[15] He later became vice president of the National Association of Industrialists, ANDI,[16] Comptroller of Bogotá[17] and Magistrate of the Council of State where, with the courage that always characterized him, he faced and survived the assault on the Palace of Justice by the M-19 in November 1985, saving the life of his colleague Lubín Ramírez who was seriously injured.
[13][23][24][5] My voice may tremble but never my morale.On October 11, 1987, while the decree for his appointment as Colombian ambassador to Washington was being processed, President Barco called Low-Murtra to entrust him with the difficult task of being minister of justice, a position that at that time meant a death sentence because his predecessors, from Rodrigo Lara Bonilla, had either been murdered or had been targeted by the Medellín Cartel.
[26] Low-Murtra confirmed the state's war against drug trafficking, and was the target of death threats after revealing that Jaime Pardo Leal, former presidential candidate for the UP, had been murdered on the orders of Gonzalo Rodríguez Gacha.
Death threats increased after Low-Murtra signed the extradition orders against the leadership of the Medellín Cartel; Pablo Escobar, Rodríguez Gacha and the Ochoa brothers.
Following the kidnapping and subsequent murder of Attorney General Carlos Mauro Hoyos, threats against Low-Murtra became more and more frequent, leading President Barco to appoint him Colombian ambassador to Switzerland.
But Low-Murtra was deeply affected by the murder of Luis Carlos Galán, and the terrorist group ETA threatened him because he was Escobar's liaison in Europe, allegedly complicit in the failed attack against Enrique Parejo González, former minister of justice and Colombian ambassador to Hungary.
On April 30, 1991, ironically 7 years after the murder of Lara-Bonilla, after his workday, Low-Murtra approached a taxi to see if he could take him, and immediately, Darío de Jesús Giraldo, a hitman in Escobar's service, killed him with 3 shots.
