Actually, Jeopardy! also came on the air in 1962. Most people know current host Alex Trebek... but how many of you recall the original host of Jeopardy, Art Fleming? And yes...Fleming's announcer then was the same Don Pardo that announces for Saturday Night Live.
And since it is an unsolved homicide in Los Angeles...and it is the Roaring 20s...and it is HOLLYWOOD, baby!... it is a popular field of study. There are books -- notably A Cast of Killers by James Kirkpatrick [Dutton,1986] that give clues and possibilities, but the Los Angeles Police Department has never closed the case.
And there are, seemingly, scores of suspects. Being a director, Taylor had many friends in that early film colony.
One of the most frequently mentioned is Mabel Normand, a highly popular commediane. Mabel was the last person -- other than the killer -- to see Taylor alive. She'd been chauffered over to pick up a book from him. Taylor was a British expat, and had a formal education; Mabel was a Sennett commedianne, and had not had the benefit of much education. In another book on Taylor's murder, by writer and publisher Robert Giroux, A Deed of Death, the writer reveals the drug world of the era; Mabel was caught up in it. Taylor was fighting it, allied with the police and working inside the studios. Giroux's book emphasises a drug hit on Taylor.
But the most widely-held theory is that he was killed because of a love affair. Mary Miles Minter was a rising star in the Hollywood scene, and had done several films under Taylor's direction. She was madly in love with him, but, though he showed her some affection, Taylor was more mindful of the years between them. So he did his best to keep their friendship open and above-board; she sent him a handful of pretty idiotic love notes, on gaudy, girlish personal stationary that one could almost see glowing through the envelope. But the real problem was not Mary, who, apparantly, was schoolgirl-sweet, but her mother, from all accounts a mean, vicious, straight-razor-totin' woman. She was determined not to let Mary (who, after all, was the cash-flow in the famiily) get into the clutches of that dirty old Taylor.
That is the primary scenario spelled out in Kirkpatrick's book. "Taylorolgy", as it has become known, is a study all its own. There are Taylor websites, books, newsletters... quite a list.
