The other fellow in the picture is Albert Salmi, one time Broadway star and character actor who murdered his wife and then killed himself.
Albert Salmi was a strange case, no previous record or anything, an acting coach. Aaccording to the daughter the wife was dying and the two of them spent the last week of their lives drinking and perhaps sharing her prescription meds. Possible mercy killing, but obviously fueled by the junk they had consumed during that week. The daughter said she knew they were acting strange, but did not think they had gone that far over the edge. I feel odd even discussing this on a thread about Mr. Parker as he was so NOT like that.
