just throwing out a couple thoughts if focusing on balding guy.
-think the black on the belt is significant clue (brought up by another anon a couple times). i.e. what is it? Looks like old school phone belt clip or pager.
-think the high waistline is significant clue- i.e. William and his age group wear pants euro/metro low hip hugger style. this guys is old school high waister i.e. Jeb (but it isn't him).
