Another post dealt with "Death Hits The Jackpot" and I realized that both Freddy and Leon Lamar were broke. Leon did own a high-end Beverly Hills jewelery store, but he was struggling. Freddy was a down-on-his-luck photographer. That may be the least "elite" in the Columbo world because Justin's nightclub looked like it was about to put him in the big leagues.
So, excepting the 87th Precinct episodes (which I erased from my mind anyway, lol), I think Freddy and Leon may take the prize. Any other nominees for least elite?
