Saudi terrorism suspect bought car in Oklahoma City

Mark White, spokesman for the FBI's Dallas office, said the investigation so far has given agents no reason to believe Aldawsari had associates in Oklahoma City or anywhere else who were involved in his alleged terrorism plot.

White declined to say what dealership sold Aldawsari the vehicle, saying he would not release any investigative information beyond what was in the arrest warrant affidavit.

�We have no indication that anyone else is involved at this point,� White said. �Of course, our investigation continues, because we want to make sure. We're not cutting out any possibilities, but at this point we have not found any indication that he's got any associates or he's associated with any terrorist groups. We just haven't seen that yet. But we continue to look. We want to make sure.�

Terrorism plots seem to have a way of finding Oklahoma.

On April 19, 1995, Timothy McVeigh used a fertilizer bomb to blow up Oklahoma City's Alfred P. Murrah Federal Building, which resulted in the deaths of 168 people. McVeigh was executed for his crime.

Six years later, it was disclosed that Zacarias Moussaoui had undergone flight training in Norman before the 9/11 terrorist attacks on New York City and Washington, D.C.

Moussaoui initially testified that he was supposed to be a participant in the 9/11 attacks, but later claimed he was supposed to pilot a fifth plane, with would-be shoe bomber Richard Reid on his crew, that would target the White House. Moussaoui is serving a life sentence.
