The FBI is trying to solve the mystery of what sounds like one of the easiest armored car heists in history.
The suspect stole $500,000 from the armored car parked right outside of Greektown Casino on Friday morning.
Investigators aren't saying what if any clues they were able to get from surveillance cameras.
The Loomis driver stayed in the driver's seat as required when another man dressed like an armored car worker prompted him to open up the rear door. He did that and then the man walked away with the cash.
If you have any information, please call the FBI at 313-965-2323.
