Argentinian filmmaker Nicolas Entel's documentary "Sins of My Father" (2009) chronicles Marroquín's efforts to seek forgiveness, on behalf of his father, from the sons of Rodrigo Lara, Colombia's justice minister who was assassinated in 1984, as well as from the sons of Luis Carlos Galán, the presidential candidate who was assassinated in 1989. The film was shown at the 2010 Sundance Film Festival and premiered in the US on HBO in October 2010. In 2014, Marroquín published "Pablo Escobar, My Father" under his birth name. The book provides a firsthand insight into details of his father's life and describes the fundamentally disintegrating effect of his death upon the family. Marroquín aimed to publish the book in hopes to resolve any inaccuracies regarding his father's excursions during the 1990s.
