That's fantastic!
By all accounts, although the witness was interviewed shortly after the abduction/murder, and there was no mention of his vehicle.
Richard Allen then described the witness' vehicle during a confession, accurately describing his vehicle as a white van.
The only way that Richard Allen knew what the witness was driving that day at that time is that Richard Allen was there, "down the hill" with Libby and Abby, when the van passed at 2:30.
During prosecution opening statements, they said that Richard Allen had information that only the murderer knew: the white van. The defence said during opening statements that they would prove that the girls were taken away in a vehicle and then taken to the ravine in the middle of the night. We're waiting to hear more about that theory.
