He claimed he met three of the Sept. 11 hijackers in Shreveport a year before the attacks.
 Now, that man, Shreveport dentist Dr. David Graham, is dead.

His family says he was poisoned more than two years ago. At the time, Graham was trying to publish a manuscript about meeting three middle easterners in Shreveport, men he feared were plotting to bomb Barksdale Air Force Base. Graham wrote that he warned the FBI. Then after Sept. 11, he saw their pictures among the hijackers.

Before Graham was poisoned, he was supposed to testify at a deportation hearing against a Pakistani man, Jamal Khan, who hosted the men Graham believed to be the hijackers. Graham's brother, Edwin Jones, told us Wednesday night the family believes someone slipped poison into his drink, plunging him into a deadly illness.
