Oakland County Sheriff Michael Bouchard said investigators were still trying to determine a motive for Tuesday's shooting at Oxford High School in Oxford Township, a community of about 22,000 people roughly 30 miles (48 kilometers) north of Detroit.
The suspect's father had bought the 9 mm Sig Sauer used in the shooting on Friday, Bouchard said, adding that he did not know why the man bought the gun. Bouchard said the suspect had practiced shooting with the gun and "posted pictures of the target and the weapon."
The three students who were killed were 16-year-old Tate Myre, 14-year-old Hana St. Juliana, and 17-year-old Madisyn Baldwin. Bouchard said Myre died in a patrol car as a deputy tried to get him to a hospital.
