i am racking my brains out for the name of the episode in which a man is leaving a ranch by car after he has commited a murder. On the way out he nearly runs over the only witness to him leaving, who happens to be blind. Can anyone help?

The episode that comes to mind is A Deadly State Of Mind. George Hamilton plays the psychiatrist murderer who is having an affair with his own patient and murders the husband in a scuffle in the house.
I don't get to see Columbo much anymore since Bravo took it off the air. It's only on Saturday afternoon now.........oh well. Hope this helps.
