 The perpetrators were apprehended in 1989 under the administration of President Carlos Salinas de <unk> . 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 .
