This undated Progress-Bulletin clipping was scanned and sent to me by Ren. Actor Mike Connors was in Pomona one summer day to film a scene for a “Mannix” episode in which his private eye character Joe Mannix returns to his hometown, Sumner Grove, to help an old friend in trouble.

Filming was done in front of the old City Hall, since torn down. “Cries of ‘hey, there’s Mannix’ were common as secretaries left the office for an extended coffee break,” the story relates. The Prog office would have been only a block or two from the filming.

“Mannix” aired from 1967 to 1975 on CBS, lasting eight seasons. It looks likely that this was the third season episode “Return to Sumner Grove,” which aired Oct. 11, 1969. Here’s the IMDB summary.

* Never mind: Microfilm research by the Pomona Public Library’s Allan Lagumbay pins the date of the article as June 16, 1971, which means the filming was for a fifth-season episode.

I don’t know that I ever watched the series; at one point it aired the same time as “The Night Gallery,” which I watched when allowed to. The AV Club wrote an appreciation of the series here.
