I found three newspapers on fultonhistory.com that listed Carl W Fritz as DA (died of accident or other causes) in 1919. The Corning 'Evening Leader' of July 10, 1919 says "Mr. and Mrs. G. W. Fritz of the town of Wheeler, have just received word of the death of their son Carl Fritz overseas. No particulars were given."
I couldn't find anything about him in 1922. There are several articles about Carl Fritz, jr. in later years.
