One inmate working in my shop assures me that he has the millenium diamond.
Apparently when the plot to steal it from the Dome came to the attention of the police a copy was made and it was switched, but the copy was so good that a mistake was made, and when the actual attempted robbery took place the real one was in the display stand.
During the confusion of the arrests our hero had been hiding in a waste bin(seems that he took certain drugs which made him smaller), he saw his chance and grabbed the gem and now the authorities are too embarassed to admit the theft.
Same prisoner also knows where Osama bin Laden is, they are good friends, OBL gave him his body warmer.
OK, if you must know OBL is hidden near the Niagara Falls in a barrel.
