AT CORNING, KERSTETTER worked as a journeyman, which means he did whatever was needed: painting offices, operating the machines, performing maintenance jobs. In 1987, when Corning was downsizing and Kerstetter’s pay was cut, he added overnight and weekend security shifts. A month before the Bradford heist, in Solon, Ohio, a night watchman vanished along with $85,000 worth of platinum. In police interviews, the executive theorized his name was on the note because a Bradford company with which he formerly did business had a grudge against him. Kerstetter would have known about the additional platinum right next to where the platinum was stolen.
