The gun used by a 15-year-old who opened fire at his Michigan high school on Tuesday and killed three pupils was purchased by the suspected shooter’s father, police said.

Eight other people were wounded, some critically, in the incident at Oxford High School in Oxford Township, a community of about 22,000 people roughly 30 miles north of Detroit.
