1924 Thomas Ince – Silent film director known as "The Father of the Western" (Custer's Last Fight) He died in his bed in Los Angeles, California. Although Ince died of a heart attack, rumours that he had been shot to death by publishing tycoon William Randolph Hearst circulated for years. A stage performer as a teenager, Ince began directing silent films in his 20s. His movies were so successful that he was able to build his own studio on a large tract of coastal land between Santa Monica and Malibu. At the Inceville Studio, he filmed many of Hollywood's earliest Westerns. Ince was at the peak of his film career when he agreed to take a cruise on William Randolph Hearst's yacht on November 16, 1924, with, among others, Hearst, Charlie Chaplin, and actress Marion Davies, Hearst's long-time paramour. While aboard the yacht, Ince suffered a heart attack. He debarked in San Diego and boarded a train to Los Angeles, where he died at home three days later. Partly fuelled by Hearst and Chaplin's inexplicable denial that they were even on the yacht when Ince suffered his heart attack, rumours began to spread that Hearst had shot Ince. There were two main theories surrounding the death: some believed that Hearst caught Ince with Davies, while others speculated that Hearst actually intended to shoot Chaplin. Although investigators confirmed that Ince had died as a result of a heart attack, the rumours continued. The rumours were so persistent that they were often reported as fact by many publications and books, and some even still believe that the Hollywood community covered up Ince's murder. Years after the incident, publications continued to print false reports that Hearst had secretly supplied Ince's widow with a trust fund because he had killed her husband

Of course he died from a heart attack. A bullet to the heart will do that. You have to wonder why the others denied even being on the yacht if everything was so innocent. There sure were a lot of suspicious deaths in Hollywood through that era.
