Among Escobar's biographers, only Vallejo has given a detailed explanation of his role in the 1985 Palace of Justice siege. The journalist stated that Escobar had financed the operation, which was committed by M-19; but she blamed the army for the killings of more than 100 people, including 11 Supreme Court magistrates, M-19 members, and employees of the cafeteria. Her statements prompted the reopening of the case in 2008; Vallejo was asked to testify, and many of the events she had described in her book and testimonial were confirmed by Colombia's Commission of Truth. These events led to further investigation into the siege that resulted with the conviction of a high-ranking former colonel and a former general, later sentenced to 30 and 35 years in prison, respectively, for the forced disappearance of the detained after the siege. Vallejo would subsequently testify in Galán's assassination. In her book, "Amando a Pablo, odiando a Escobar" (Loving Pablo, Hating Escobar), she had accused several politicians, including Colombian presidents Alfonso López Michelsen, Ernesto Samper and Álvaro Uribe of having links to drug cartels. Due to threats, and her cooperation in these cases, on 3 June 2010 the United States granted political asylum to the Colombian journalist.
