S06:E12 - Bitter End

On December 21, 1998, two gunmen kidnap three janitors on their way to clean the Bank of America ATM repository in Las Vegas. The gunmen force the janitors to let them in the ATM repository and hold them hostage until the armored car guards arrive to make their nightly collection. When the guards enter the bank, the gunmen surprise them and shoot one guard in the chest before escaping with $1,088,000, the largest bank robbery take in Las Vegas history.
