An Unsolved Mystery

Hi everyone .. today I get to solve this mystery ... here we go!

It's obvious that the guy in the purple sweater is a criminal who first of all broke the law by robbing a bank. How is that obvious? Well, a camera from a shop in front of the bank filmed everything about the crime comitted and in the tape you can see clearly everything (picture number one). 
Police catched him easilly because he didn't have car, he was just running around carrying the money.  
In the confession room (picture number two), he didn't have an alibi, he just told the detective that the guy from the video wasn't him, but you'll see... our detective is a professional and he knows that this guy is the real thieve even though he cried as a baby as you see in picture number three. 
This guy went to jail and this crime is no longer an Unsolved Mysterie.
