I guess you all know why. I was only 15 when it happened but I'll always carry it with me.
For the ones that were involved and got away, I hope John Doe II catches his just dues, slowly and painfully.

No, too many witnesses of two men in the truck.

The two sketches came out at the same time - the day after.
That is how they recognized McVeigh in the Perry jail.
One is good and the other is false?

If i recall right, i watched the Timothy McVeigh confessional a while back, he barely mentioned Terry Nichols so I doubt there was more than those two involved. He talked about how he was really worried about the bomb going off at the red light before he could park and how the cab filled with smoke from the fuse and such.

McVeigh also claimed the FBI cut a RFID chip out of his ass cheek on the flight back from the Perry jail.
National Public Radio had an interview with a half dozen witnesses who saw two men in the truck. The FBI took 4 different tapes from security cameras on different buildings showing two men in the truck.
They lost them.
Of the ten people (family members of victims drawn by lot) allowed to see McVeigh's funeral, the comments were he looked at each of them and died silently.
He may have had a martyr complex.
