Frank Wright reportedly told Dallas reporter Earl Golz that he saw a second man leaving on foot.
If it was to Golz, then it was 10-15 years after the fact. The Nashes' quotation of his story appears to be complete, and a second man disappearing from the scene was exactly the sort of thing that the Nashes were looking for.
Also, of Markham, Benavides, Scoggins, the Davises, Clemons, and (yes) Mrs Wright, how many others saw the car and man that Wright claims to have seen?
There's one more thing to consider with regard to Frank Wright. As I wrote in another forum a few years back:
"The fun part about Mr Wright's testimony is that it's a complete outlier from the rest, until you read Jimmy Burt's FBI 302. In Burt's version, the car is his (though it's a two-tone '52 Ford rather than a two-tone '51 Plymouth). Burt claimed that he drove up to Tippit's car, got out to see that Tippit was dead, then got back in and drove off.
"Oh, and did I mention that Burt and Wright lived in adjacent buildings (ie, 501 and 505 10th St)?"
