(Le Sueur County, MN)  —  A man is admitting to stabbing his father to death before setting their home in rural southern Minnesota on fire.  Hardy Wills-Traxler pled guilty yesterday to second-degree murder in connection with the death of 64-year-old Bruce Traxler.  The father and son lived in a shed on the Le Center property that included living quarters.  Wills-Traxler is expected to receive a sentence of just over 25 years and will likely serve the first 16 years in prison with credit for time in jail since his arrest.
