He did not describe to the court what the video contained . It was not immediately clear whether the military would look into why the video was ordered deleted . A Fort Hood official , who insisted on anonymity because of the ongoing criminal investigation into the shootings , said , `` Since this matter was raised during the Article 32 hearing , it is for the Article 32 hearing officer to decide whether to make further inquiries to the soldier 's chain of command for additional information .
