We all have listened to Randy's clues

about long hair and beard
i found one that caught my attention it might not be right

but chapter 23 part 1
when he was first seen
michael mentions that "at the front of all of them, one taking lead grabbin tanyas visible body"
or something like that
so we can assume he leads groups of zombies

one thing i never understood....
was when steven said "did you see that? some of them were burn"
how is that a key to us? anyone has any ideas about why there were burn zombies?
