Side by side photos of shooter, years apart. No ‘13’ on neck in older photo.
There is no "13" on the other picture either, just a skin fold "turkey neck" kind of thing.
“No 13 on neck in older photo.” —
That pic is cropped too high to see where some people see the “13” on the full “eyes closed” photo. It’s there, but I think it’s more a photo artifact of a neck gobbler.
