Authorities: Student kills 3, wounds 8 at Michigan school

OXFORD TWP, Mich. — A 15-year-old sophomore opened fire at his Michigan high school on Tuesday, killing three students and wounding eight other people, including one teacher, authorities said.

Oakland County Undersheriff Mike McCabe said at a news conference that investigators were still trying to determine a motive for the shooting at Oxford High School in Oxford Township, a community of about 22,000 people roughly 30 miles north of Detroit.

McCabe said he was aware of allegations circulating on social media that there had been threats of a shooting at the roughly 1,700-student school before Tuesday’s attack, but he cautioned against believing that narrative until investigators can look into it.
