Joe noted that in the 1930 U.S. Census, Walter M. Piggott was an inmate at Leavenworth prison. I found the following article: Re: Warren M. Piggott Cass City Chronicle Cass City, Michigan Friday, October 4, 1929 Declaring that Warren M. Piggot, Bay City furniture dealer, is responsible for a loss of $1,0000.000 by business firms in this country, Federal Judge Arthur J. Tuttle Friday evening sentenced him to the maximum term for use of the mails to defraud of 10 years in the United States penitentiary at Leavenworth, Kans., after the jury had returned a verdict of guilty on all of the 13 counts in which the government charged Piggott with wrongdoing.
