One Tree Hill and Casey Anthony

I noticed in the second document dump that "One Tree Hill" was one of the search items on the Anthony computer, so I thought I'd look into the cast members of the show to see if Casey could have gotten some of her imaginary friend's names from the cast of One Tree Hill.
This is what I've discovered:

Amber Wallace plays Glenda Farrell. (Raquel Farrell)

Ashley Richards plays Samantha. (Zenaida's sister)

Zachary Dylon Smith plays Young Dan. (Jeffrey Hopkins' son)

Thomas Ian Griffith plays Larry Sawyer. (Thomas Franck)
