APPLETON, Wis. (AP) — Prosecutors say a 17-year-old accused of killing his grandparents in eastern Wisconsin typed out plans for the shootings. Alexander M. Kraus was charged Tuesday with two counts of first-degree intentional homicide for the deaths of 74-year-old Dennis Kraus and 73-year-old Letha Kraus Sunday at their home in Grand Chute. Each charge carries a life sentence. The complaint says the plans for the killings were found in a backpack along with a book about an executioner. The document does not indicate a motive. Police said Alexander Kraus told investigators he also was planning to cause harm at his eastern Wisconsin high school, which is not mentioned in the complaint.
