IIRC the photos sourced from Libby’s phone which ISP later released were taken from a blurry and fuzzy video of him quite some distance away. During one police update, it was mentioned both Disney and NASA assisted the FBI in attempting to add clarity to the images as best they could.

I’ve always thought it interesting how these two photos don’t quite resemble the same person. BG on the left looks to me far younger and leaner than BG on the right. BG on the right, it appears a hoodie entirely covers his head/hair and his beard appears it might be somewhat grey or heavily grey tinged. It’s also possible he might have a protruding pot belly.
If LE is able to connect TB to the Delphi murders of Abby and Libby, I think the photo on the right is a very close likeness to him.
