I wonder if the couple even had the money on them. Don’t Casinos usually pay with a check and withhold taxes on sums that large?
I don't know what the options are for paying out casino winnings are these days. It is been a bunch of years but there was a similar type case in my area. Somebody won big at a gambling boat with a take of around $25K. The victims took the winnings in cash and were robbed at some point during there travel back home across the state. Fortunately for the victims, they were not injured. The robbers were caught because of casino video cams and cell phone pings of 2 different cars following the victims..
