First-degree intentional homicide charges have been filed against a 42-year-old father in his teenage son’s shooting death. Kayle Fleischauer is being held in the St. Croix County Jail. Nineteen-year-old Chase Fleischauer was found suffering a head wound in his father’s home near New Richmond last Saturday. The son’s friend says he had traveled to Wisconsin to spend Friday night with his sister. He lived full-time with his mother in St. Paul and attended college in Minnesota.
