The ongoing criminal investigation led to a May 2011 court order that Allende's remains be exhumed and autopsied by an international team of experts. Results of the autopsy were officially released in mid-July 2011. The team of experts concluded that the former president had shot himself with an AK-47 assault rifle. In December 2011 the judge in charge of the investigation affirmed the experts' findings and ruled Allende's death a suicide. On 11 September 2012, the 39th anniversary of Allende's death, a Chilean appeals court unanimously upheld the trial court's ruling, officially closing the case.
