A very successful brush salesman, very popular with the ladies on his route, went missing with no trace. His remains are found when a duck pond is drained; the team seeks to solve the 1967 murder. Fingerprints reveal the victim had a violent past, gave most of his earnings away, and had no personal life. Suspects from his route include a belligerent Vietnam vet with hoarder tendencies and a jealous, controlling husband.
