ST. LOUIS • Monday morning's robbery of ATM Solutions was reminiscent of events on Oct. 23, 1992, when two men in white overalls and stocking masks tied up a Brinks guard and slipped away from a building that was crowded with construction workers. The take was about $847,000.

The cash was untraceable. Investigators never got a decent lead on the robbers or the money, and the FBI considers the case unsolved and closed.

It was St. Louis' biggest cash heist, unless the undisclosed haul in Monday's was more.

The 1992 case began when Brinks guard Clyde Blakey took a freight elevator to the basement of the United Missouri Bank, 10 South Broadway, and picked up bills of varying denominations stuffed into five bags. He made the pickup at 3:45 p.m. on a Friday afternoon and was to take the money for sorting to the Federal Reserve Bank downtown.

While pushing the bags down a hallway in the former Equitable Building, he was stopped by a masked man armed with a revolver. The gunman and his accomplice bound Blakey with rope and tape. Blakey said later that one robber spoke only in whispers, and the other never uttered a sound.

The robbers disappeared. Blakey freed himself in about 30 minutes. Two hours after the robbery, a cleaner entered a 13th floor restroom of the building and found paper jumpsuits, tape, pantyhose and $1,100 stuffed in a trash can.

Investigators quickly cleared Blakey and his driver, who had stayed with the truck on the street. Police interviewed dozens of construction workers who were renovating the office tower but picked up no good leads. Detectives believe the two robbers dumped their jumpsuits in the upstairs bathroom, went back down to the third floor and escaped with their cart of bagged money across the pedestrian bridge to the Stadium South garage.

Blakey retired four years later and still lives in Velda City. He declined Monday to be interviewed about the new robbery.
