On the night of Friday 12 September 1997, six men entered the Dunbar Armored regional depot on Mateo Street in downtown Los Angeles and left roughly half an hour later with US$18.9 million in cash. No shot was fired. The operation was organised by Allen Pace III, a Dunbar regional safety inspector from Compton who had walked the building legally for months and who had been fired the day before for tampering with company vehicles. By volume of cash carried out the door, it remains the largest cash robbery in United States history; only the 2024 Easter Sunday burglary of a Los Angeles money-storage facility, estimated at more than US$20 million, is sometimes ranked above it, and even that comparison is contested.
The outcome is settled, and this file states it without suspense. Pace and his five childhood friends were caught, and the principals were convicted in federal court. Pace was sentenced on 23 April 2001 to 24 years in prison and was released on 1 October 2020. The recovery of the money, however, failed almost entirely. Less than a third of the haul — roughly US$5 to 7 million, depending on the source — was ever traced, leaving in the region of US$12 to 14 million unaccounted for more than two decades later.
The case is studied because its two halves point in opposite directions. The theft itself was a near-textbook inside job: a trusted employee who knew the camera arcs, the guard routine and the vault schedule, paired with a small crew and an alibi built at a house party before the raid. The crew left almost no forensic evidence at the scene. What it could not control was what happened to the cash afterward. The investigation that broke the case did not begin with the robbery at all; it began two years later, when one robber paid a real-estate broker with banknotes still bound in their original Dunbar currency straps.
The Dunbar robbery is therefore less a story about defeating a vault than about the gap between stealing money and keeping it. The crew solved the first problem with insider knowledge and discipline, and was undone by the second through ordinary impatience and the simple, traceable fact of branded cash.
On the evening of 17 January 1950, seven masked men walked out of the Brink’s, Inc. armored-car depot at 165 Prince Street in Boston’s North End carrying roughly US$2.775 million — $1,218,211.29 in cash and $1,557,183.83 in checks, money orders and securities — in what was then the largest robbery in American history. The operation was organized by Anthony “Tony” Pino, a Boston career criminal who had spent some two years casing the building, and executed by a crew of eleven that included Joseph “Specs” O’Keefe, Stanley “Gus” Gusciora, Joseph McGinnis and Henry Baker. For a time it looked like the title the press gave it: the perfect crime.
It was not. This file states the outcome plainly. The case broke almost exactly six years later, and it broke from the inside. On 12 January 1956 — five days before the federal statute of limitations on the robbery would have expired on 17 January — the FBI arrested the core of the gang. The decisive cause was not forensics or stakeouts but a defection: O’Keefe, embittered over money and nearly killed by a hired gunman, agreed to talk. Eight of the conspirators were convicted later in 1956 and sentenced to life imprisonment; two others died before they could be tried. Of the more than $2.7 million taken, only about $58,000 was ever recovered.
What makes the Brink’s job a durable teaching text is the gap between its operational brilliance and its human fragility. The entry was a masterpiece of patient reconnaissance: the crew had let themselves into the building repeatedly at night, removed and copied the lock cylinders on five successive doors, and rehearsed the raid until it took minutes. Dressed in near-identical Navy pea coats, chauffeur caps and rubber Halloween masks, they moved as an interchangeable unit that left witnesses with nothing to describe. The plan that defeated the building, however, could do nothing about the eleven men who knew the secret, the money they could not safely spend, and the six years they had to keep quiet. Brink’s, a firm whose entire business was the secure movement of cash, had left a count-room reachable through a sequence of ordinary locks that a patient crew could defeat one at a time, with no one positioned to stop five employees being surprised on a quiet weeknight — proof that a hardened target can be undone by the routine around it.
