Burt Henry McMahon, a 47-year-old oil executive from Sonoma, California and co-owner of North Bay Oil Company, was murdered in Las Vegas after attending a business convention. He attended the Inter-Mountain Oil Company Convention at Caesar’s Palace and was at a banquet at the Library Buttery and Pub on the evening of February 16, 1982. McMahon was last seen alive about 8:45 p.m., waving to friends as they left in a rental car and leaving him standing in front of the restaurant; his rented car remained undisturbed in the restaurant parking lot.

About 9:30 p.m. a passing motorist found McMahon’s body on the side of East Lake Mead Boulevard near Sunrise Mountain, a 23 to 26 minute drive from the restaurant. He had been shot multiple times in the head and body, and robbery was ruled out because his cash and jewelry were still on him. Investigators explored leads including possible ties to organized crime and a theory involving a prostitute but found no evidence to support either. No suspects have been identified and no arrests were made; the case remains unsolved.

If anyone attended that convention or remembers seeing McMahon that night, any information could be helpful.
