Escape prison & Lose the cops under a minute - Mafia Definitive Edition

Made this because I was stuck here and found it very difficult to get out and going. Getting this far was pretty straight forward so left out all the shooting. I saw players getting trough the yard which is the most obvious. Almost made it too. I saw posts in Reddit suggesting you should go back inside prison and wait 5 min for cops to go away. I waited 10 mins so this didn't work. Then there was this one message saying about a hole on the second floor. Heck... the game was hinting about this hole right in the beginning when you were coming to the prison.
