Q: What was done after the investigation announcement?, Context: On the afternoon of Gaddafi's death, NTC Prime Minister Mahmoud Jibril publicly revealed the news. Gaddafi's corpse was placed in the freezer of a local market alongside the corpses of Yunis Jabr and Mutassim; the bodies were publicly displayed for four days, with Libyans from all over the country coming to view them. In response to international calls, on 24 October Jibril announced that a commission would investigate Gaddafi's death. On 25 October, the NTC announced that Gaddafi had been buried at an unidentified location in the desert; Al Aan TV showed amateur video footage of the funeral. Seeking vengeance for the killing, Gaddafist sympathisers fatally wounded one of those who had captured Gaddafi, Omran Shaaban, near Bani Walid in September 2012.
