The concept of robbing a heavily fortified casino has been the subject of countless Hollywood blockbuster movies.

Because they act essentially as unregulated banks handling millions in cash daily, they have always attracted audacious thieves.

Bill Brennan and the Perfect Disappearance

In 1992, a sportsbook cashier pulled off the ultimate inside job, stealing half a million dollars without firing a single shot.

Despite being featured on America's Most Wanted, Brennan completely vanished and has never been seen or heard from again.

• The sheer simplicity of the crime is what makes it so legendary among true-crime enthusiasts
• He specifically targeted the sportsbook because it held massive amounts of untraceable, non-sequential cash
• To this day, the FBI has absolutely no solid leads on his whereabouts or his fate

The Most Famous Card Counters in History

A group of brilliant students from the Massachusetts Institute of Technology used advanced mathematics to drain millions from Vegas.

Throughout the 1990s, the team created a complex system of 'spotters' and 'big players' to disguise their card counting.

Modern casino thieves have abandoned guns in favor of complex cyber-attacks and sophisticated digital hacking schemes.
