The case involved an alleged furnace failure that caused a major fire loss of a building in March 1992 in Delaware County, New York. Five months after the building had been unceremoniously relegated to a dump, the alleged offending oil service company was notified of a law suit. The only piece of evidence that was retained from the investigation by the New Jersey-New York based investigation company for review by other experts was a single furnace nozzle which they declared the culprit. Attorney George Roesch of Mac Vean, Lewis, Sherwin and McDermott of Middletown, New York received the case to review on behalf of the oil service company.
