Just jumping off your post.
The problem with the CCTV is that it provided side views of the vehicles only. And they may not have been able to identify all of the vehicles that passed by at the relevant times. I don't think we have ever heard if there were cars that were still not identified?
(Pretty sure this article is not paywalled.)
Investigators will today set up at the Kendall Tennis Club with still images taken of all cars captured on the club’s CCTV camera on the morning William went missing in the hope of identifying any suspicious vehicles.
Port Macquarie Superintendent Paul Fehon, who is leading the investigation into the three-year-old’s disappearance nine weeks ago, said police were asking everyone who drove past the Graham St club before 11am on September 12 to come forward and identify their vehicle.
“We’re trying to match them up to see if we can eliminate the local cars and then see if we’ve got cars that are unusual,” Supt Fehon said.
“Unfortunately, it’s not a head on or behind shot where we would have number plates, it’s only descriptions of cars.
“We’ll look at the side profile of a car and if we can’t find identify some then we may have a new line of inquiry.”
