9. The United California Bank Heist
Stolen: $30 million
Amil Dinsio, an Ohio professional criminal, gathered a team of six thieves and flew them to California in 1972. They rented a townhouse and plotted a bank robbery after hearing (mistakenly) that President Richard Nixon maintained a multimillion-dollar slush fund there.
After methodically washing down the townhouse, the group dynamited their way into the vault, grabbed $30 million in cash and valuables, and fled.
The burglars have finally been identified thanks to a significant tip supplied to a taxi driver and fingerprints recovered on the inside of the town home’s dishwasher.
