IRON LITTLESOCKS ATM CONTEST - Little Rock Bank

Little Rock Bank, for all your cash in hand needs (the wild west doesnt have contactless yet). Sadly the bank has fallen victim to an outlaw gang who fled through the local mining Co tunnels, however in the commotion we believe 3 of the thieves were left behind & forced to hide at the very scene of the crime. Can you help find them & send them to the Sheriff's jail? - And perhaps whilst at it recover some of the stolen money so we can pay the CEO and Chief execs their annual bonuses..
