Beverly Hills Safe & Lock in Los Angeles was nearly robbed over Memorial Day weekend in May of 1992. The break-in was carried out by Vietnam War veterans Art Franklin, Gene Delgado, and John Rourke, though it was masterminded by Eleanor Wish. Franklin and Delgado tunneled under the building during the weeks leading up to Memorial Day weekend, setting off the Bank's alarm in the process. Their intended target was the security box of Nguyen Tran, which was known to contain roughly $18-million in diamonds. Having discovered the nature of the September 1991 break-in at the WestLand National Bank based on his investigation into the murder of Billy Meadows, LAPD detective Harry Bosch determined that the Safe & Lock would be the next target of the WestLand robbers.
