An unscrupulous lawyer, in cahoots with Rice’s valet, Charles Jones, had concocted a plot to steal the fortune by means of a forged will. Impatient for Rice to die, the crooked lawyer and greedy valet suffocated him. They might have gotten away with their scheme; however, the next day, they tried to cash a check written out to the lawyer by the valet.
