I FOUND THE CLUE FROM THE SEASON 3 FINALE!!

Its not red sweater guy either its red shirt guy!!

When Jane is talking to Carter the camera switches to show whats behind Jane.
Janes head is blocking the word "cappachino" so all you see is the word "CAP"
Right then a man in a red shirt and a black cap appears.
He is shows for a few seconds them the camera changes.
The camera goes on him again and then Jane and Carter stand up while he is in the background.
Now listen this man is 5 feet behind Carter when Jane shoots.
All hell breaks loose and everyone runs then Jane sits back down.
A good 3 MINUTES goes by then the cops come.
-Right after the cops come you see the guy again!!!
In reality he woulda been long gone by then.
The whole mall cleared out!
You see him run across the screen behind Jane blatantly as the cops close in.
He kinda looks like Macalister but maybe not....
Please go back and watch and tell me what u think..
Somebody PLEASE screenshot it and enlarge it for me i am not good at that, d666 I'm looking at u lol.
*this is deff the clue Heller was speaking of the is blatantly shown 4 times for a reason.
And the end when he runs across 3 minutes after the mall cleared out proved it to me.
