WASHINGTON (AP) - Federal law enforcement officials say the suspected Fort Hood, Texas, shooter had come to their attention at least six months ago because of Internet postings that discussed suicide bombings and other threats. The officials say the postings appeared to have been made by Maj. Nidal Malik Hasan, who was killed during the shooting incident that left least 11 others dead and 31 wounded. The officials say they are still trying to confirm that he was the author. They say an official investigation was not opened.
