investigators have found major hasan had mor unexplained connections to people being tracked by the fbi than just the radical cleric in yemen we reported on last night so, today, invtigators continued to run down leads on what led to the attack. just before the memorial service began, four fbi agents showed up at the killeen mosque where hasan has prayed and searched a trash bin outside. the mosque president was clearly upset as he was called back from the service to sign a document, apparently authorizing the search. >> we're concerned any time a house of worship or a mosque is searched in this

muslims in the service to morally justify being in a military that seems constantly engaged against fellow muslims." under comments, he wrote, "we love death more than you love life." and his conclusion was that muslim soldiers be given the option of being released from the military to decrease what he called at adverse events." >> it's clear thatted he conflicts after this subject. it is

with this radical cleric in yemen who authorities consider a recruiter for al qaeda. u.s. officials now confirm hasan sent as many as 20 e-mails to the recruiter, which authorities intercepted but later deemed innocent or protected by the first amendment. the fbi said yesterday it turned over the information about the e-mails to the army, but defense department officials today deny that. what happened, officials say, is that the e-mails were given to one military investigators on a joint terror task force who concluded they did not merit further investigations. the e-mails were never forwarded to the pentagon, and the army it says did not learn of them until after the shootings, charlie. >> was there any explanation why they didn't warrant further investigation? >> they say they dealt with religious issues, seemed innocent and protected by the first amendment. >> all right, brian ross, reporting again tonight. in other news, in the state of virginia, the way has been cleared
