Young Richard Lindsey, one of the three American hunters, whose remains were found in the Gaspé bush in July 1953, would have given Coffin this multi-use pocket knife for having helped them to fix the pick-up truck. That knife was a graduation gift he had received from a relative in the US Air Force in Japan. Coffin had diagnosed that the gas pump was defective. The young Lindsey accompanied Coffin to Gaspé to buy a new one. They indeed bought a new one but it was never installed. This brand new gas pump was later on found in the apartment of Coffin’s mistress in Montréal.
