Background: William Cunningham Deane-Tanner was born into the Anglo-Irish gentry on 26 April 1872, at Evington House, County Carlow, Ireland, one of five children of a retired British Army officer, Major Kearns Deane-Tanner of the Carlow Rifles, and his wife, Jane O'Brien. His siblings were Denis Gage Deane-Tanner, Ellen "Nell" Deane-Tanner Faudel-Phillips, Lizzie "Daisy" Deane-Tanner, and Oswald Kearns Deane-Tanner. The Home Rule MP Charles Kearns Deane Tanner was his father's youngest brother. From 1885-1887 Taylor attended Marlborough College in England.
Context: In Taylor's pockets, investigators found a wallet holding $78 in cash, a silver cigarette case, a Waltham pocket watch, a pen knife, and a locket bearing a photograph of actress Mabel Normand. A two-carat diamond ring was on his finger. With the evidence of the money and valuables on Taylor's body, robbery seemingly was not the motive for the killing; however, a large but undetermined sum of cash that Taylor had shown to his accountant the day before was missing and apparently never accounted for. After some investigation, the time of Taylor's death was set at 7:50 pm on the evening of 1 February 1922.  While being interviewed by the police five days after the director's body was found, Mary Miles Minter said that following the murder, a friend, director and actor Marshall Neilan, had told her that Taylor had made several highly "delusional" statements about some of his social acquaintances (including her) during the weeks before his death. She also said that Neilan thought Taylor had recently become "insane".  In the midst of a media circus caused by the case, Los Angeles Undersheriff Eugene Biscailuz warned Chicago Tribune reporter Eddie Doherty, "The industry has been hurt. Stars have been ruined. Stockholders have lost millions of dollars. A lot of people are out of jobs and incensed enough to take a shot at you."  According to Robert Giroux, "The studios seemed to be fearful that if certain aspects of the case were exposed, it would exacerbate their problems." King Vidor said of the case in 1968: "Last year I interviewed a Los Angeles police detective, now retired, who had been assigned to the case immediately after the murder. He told me, 'We were doing all right and then, before a week was out, we got the word to lay off.'"
Question: What was the motive?. Whats the answer?
