El circo (song)
The lyrics describe two brothers, "Carlos" and "Raúl" (in reference to Carlos Salinas de Gortari, president of Mexico from 1988 and 1994, and his brother Raúl Salinas de Gortari), who form a "circus" (a drug cartel) and get rid of the other "circuses" in the country. After the brothers get wealthy, Raúl makes Carlos' money disappear (a reference to the Mexican peso crisis) and their circus ends. Raúl is jailed, while Carlos leaves the country, and the people are finally at peace, unless another circus arrives and the story repeats itself.

The perpetrators were apprehended in 1989 under the administration of President Carlos Salinas de Gortari. Moro and Zorrilla were sentenced to 25 and 35 years in prison respectively, but were released from prison in February 2009 for good conduct after serving at least half of their sentences. Several public intellectuals, journalists, press freedom organizations, newspapers, and politicians protested their releases. Zorrilla returned to prison later that year after he failed to provide a formal letter petitioning his release. On 10 September 2013, Zorrilla was released from prison after a Mexico City judge granted him the opportunity to fulfill the remaining years of his sentence at his residence due to unstable health conditions. The Mexican government closed the case after the arrests, but many journalists doubted the results of the investigation and believed that the masterminds behind the murder case remained at large.
