You mean the third pic of the guy in the green surgery suit with the yellow gloves? That's Jack Klugman as Quincy, M.E., an old mystery show based on the cases of an LA coroner, which was cancelled in the early 80s but is still shown in syndication. Inevitably, when Quincy's boss would declare a case to be a simple death, Quincy would somehow discover "it was murder!" :)
