I found this on YouTube – Why the ONE-ARMED MAN from THE FUGITIVE could not have been the one who did it! – YouTube Video LandumC goes there: https://www.youtube.com/watch?v=pV9_2hIrC2g (about 9:21 minutes long).
Compare and contrast to this YouTube video: The Fugitive TV Series – Final Episode (5 minutes) from 1967 – YouTube Video sr60630185: https://www.youtube.com/watch?v=CDb7pligfRA (around 4:44 minutes long).
I liked this show when it was on TV. Both videos do not have closed captioning or transcripts. I forgot the wife was strangled which would be hard for a one-armed man to do.
