Walt, in the wallet video, @4:03, the officer running is passing a Chevy on 10th?
In my book that's a 60 Impala Cabrio.
The cop is running beside a 1960 Impala convertible.....At 1:39 and at 2:49 The tail lights of a light colored 1961 Chevrolet can be seen in the background behind the wallet in the cops hand. That 1961 Chevy was parked in the parking lot behind Ballew's Texaco Station. The 1961 Chevy was parked in the parking space to the right of the 1954 Oldsmobile that they claimed the white Jacket was found beneath.
A person may have to be an old car buff like me to recognize the difference in the tail ights..... The 1960 Cheyy Impala had three lights side by side on each side of the rear .....They were mounted on a sheet of machine finished aluminum..above the bumper and beneath the deck lid.
The 1961 Chevy was similar but definitely different....in that the machined aluminum had been deleted and the red lens were beehive shaped....as seen in the background behind the wallet....
