The High Commissioner said that this ruling, together with the jurisprudential precedents established in other transitional justice cases, such as Sepur Zarco, Dos Erres, Plan de Sánchez and Myrna Mack, sends a clear message that it is possible for Guatemala to advance in the fight against impunity of the past, which in turn, strengthens the fight against the impunity of the present and the consolidation of the rule of law. On 4 May 2004, the Inter-American Court of Human Rights had already held the State of Guatemala responsible for the enforced disappearance of Marco Antonio.“
I pay tribute to the Molina Theissen family for their courage and perseverance to fight for over three decades for their right to justice and the truth,” Zeid said. Emma Guadalupe Molina Theissen was detained at a military checkpoint on 27 September 1981 and transferred to the “Manuel Lisandro Barillas” Military Brigade in Quetzaltenango, where she was held captive, interrogated, subjected to torture and other cruel, inhuman or degrading treatment, as well as sexual violence. She escaped on 5 October 1981. The following day, her 14-year-old brother Marco Antonio was taken by force from the family’s home in Guatemala City, put into a nylon sack and taken to an unknown destination in a vehicle with an official Government license plate. He has never been found.
