Early Life and Marriages
Anna Schulze, born on June 22, 1894, in Niederwald, Texas, was a member of a prominent local family. In June 1921, at the age of 27, she married Kurt Schroeder, a German immigrant. Tragically, just three months into their marriage, Kurt died in September 1921. His death was initially attributed to complications from an appendectomy. Anna's dramatic mourning at his funeral drew attention, but no suspicions were raised at the time. In 1922, Anna married William Louis Hauptreif, a widower with four children: Walter, Lydia, Hubert, and Annie. William's first wife had died in 1916 during childbirth, leaving him to care for their children. Anna had known the Hauptreif family since childhood, making her a familiar presence in their lives.The Mysterious Deaths
