Paul J. Lentz was 14 when he was last seen in Frederick, Maryland, on June 18, 1975; he had planned to go bowling that evening and did not return. Six days later, on June 24, a state road crew discovered his body in a drainage ditch in a rural part of Frederick County.

An autopsy determined Paul had been fatally stabbed with a hunting knife; the knife was recovered near his body. There were no immediate witnesses, and investigators were unable to establish how he came to be in that remote location. The case was never solved and no arrests or suspect identifications have been announced.

Anyone who knew Paul, remembers his plans that night, or has information about activity in rural Frederick County in June 1975 is asked to come forward with tips.
