In 2009, the IACHR held that the amnesty law of 1996 did not apply to the most serious crimes committed during the civil war. This was followed by investigations in the United States against people suspected of involvement in the massacre. In May 2010, Gilberto Jordan, naturalized American and former member of the Kaibiles special forces, was accused of involvement in the massacre and arrested in Florida by U.S. Immigration and Customs officers. On 16 September 2010, after his role in the massacre was established in a Miami court, Jordan was convicted for naturalization fraud and is serving a 10-year prison sentence in FCI Miami. He is expected to be released on 29 March 2019.
