After the murders of the student leaders, Ligorría spoke at some rallies in college and participated in the demonstrations that took place. On Saturday September 15 at 14:15 hours he left for Panamá along with Marco Tulio Montenegro and Byron Milian Vicente. Montenegro returned to Guatemala on 11 November 1989 to rejoin the AEU, but he was already a suspect, and was killed with knife soon after. Meanwhile, Ligorría was appointed head of research of public prosecutions. On September 12, 1997, the Guatemalan National Revolutionary Unity, which became a political party after the peace accords, formally accused Ligorría for his involvement in the murder of the student leader, claiming that he was a member of military intelligence.
