Chenoweth-Mann Murder Case
Mann was, in fact, arrested and tried for the murder. His first trial in the spring of 1884 ended in a hung jury with the jurors evenly split. He was retried in August of '84 and found guilty, but the Missouri Supreme Court overturned the verdict on a technicality. His third trial in the spring of 1885 again ended in a hung jury. He was in the midst of his fourth trial in August of the same year when he was killed in his cell at the Newton County jail in Neosho by a mob that broke in, bent on vigilante justice.
When I first started researching this case, I, too, thought, based on the superficial evidence, that Mann was probably guilty. However, the more I researched it, the more doubt I began to have to the point that I now think that it is just about as likely that he was not guilty as it is that he was guilty. For more details on this interesting case, check out my book when it is released (probably within the next few days).
