Herbert J. Strehl, 75, an immigrant from Germany who built a tool and die company in Salt Lake City, was found shot and bound in a Parleys Canyon quarry on the evening of December 3, 2000. A neighbor had seen Strehl leave his Olympus Cove home that afternoon in his gold 2000 Jeep Cherokee, followed by an unidentified driver in Strehl’s green Mercedes; both cars returned about 5 p.m. The neighbor later saw the Jeep leave again with two hurried occupants.

Strehl’s body showed multiple gunshot wounds to the head; investigators noted the killing was execution-style and were unsure whether the quarry was the primary crime scene or a dump site. Strehl’s gold Jeep Cherokee was never recovered. Detectives investigated robbery and examined Strehl’s business history — including an environmental order in 1989 that led to an alleged illegal soil dump, recent layoffs, and the disbarment of his attorney amid a related cover-up — but no arrests or public suspect identifications have been announced and the case remains unsolved.

Does anyone have information about Strehl’s movements that day or the whereabouts of the gold Jeep Cherokee?
