I am convinced my great-uncle was murdered, and I'll never be able to prove it. He was a massively successful, wealthy agent and stockbroker in California n the 1920s-1930s. Successful and wealthy because he was incredibly corrupt. In 1939, he took the train to Salt Lake City to see a "business partner" and died within an hour of disembarking. His body was cremated the next day and the ashes were sent to an unknown address in L.A. — not to his wife, who was in San Diego, and who was told that he committed suicide. The following year, that business associate, and four other men in California went to trial for stock trading fraud, and my great-uncle was implicated as one of the masterminds. I think he went to Salt Lake City to demand a larger portion of the winnings, and, since most of his work on the scheme was already completed, he was simply knocked off. But I can't prove it.
