OXFORD TOWNSHIP, Mich. (AP) — Authorities say a 15-year-old sophomore opened fire at his Michigan high school on Tuesday, killing three students, including a 16-year-old boy who died in a deputy’s patrol car on the way to a hospital. Eight other people were wounded, some critically. Oakland County Sheriff Michael Bouchard says investigators are still trying to determine a motive for the shooting at Oxford High School in Oxford Township. He says the suspect isn’t talking. 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.
