Investigators from the Fort Hood shootings say that Nidal Malik Hasan acted alone and that no evidence supports the theory that Hasan had outside help or orders about the massacre. Though in late 2008 Hasan did communicate with radical imam Anwar al-Awlaki, an American-born Yemeni who now lives overseas and has ties to terrorist groups, the messages "did not advocate violence or threaten violence." Sources say that the communications were consistent with Hasan's research as an Army psychologist on post-traumatic stress disorder. The FBI has launched an investigation into how it handled, or perhaps mishandled, the information it had on Hasan.
