COCEI
The resignation request was the culmination of many accusations having been made in recent years. Reyes had previously complained of accusation made against him, citing him as a Marxist guerrilla and murderer, stating Reyes had engaged in gun-running, fomenting political instability and aiding guerrilla movements. These accusations stemmed from Reyes support of the Coalition of Workers, Peasants, and Students of the Isthmus (COCEI), which the government believed Reyes support directly influenced the groups rapid growth. For instance, In May 1979, Reyes was asked on behalf of COCEI family members who went missing or were taken prisoner, to assist in securing their release, something the government did not look favorably on. In response to the accusation and the Reyes-COCEI relationship, the government closed churches and expelled diocesan workers. The government however failed to provide any evidence show a direct link between Reyes and the actions of the COCEI.
On June 29, 1995, gunmen opened fire on Reyes in an assassination attempt. The attack was believed to have been brought on due to his role as chairperson of the Tepeyac Human Rights Centre in Tehuantepec.
