James and Jennifer Crumbley, whose son murdered four classmates and shot seven other people at Oxford High School in 2021, were each sentenced Tuesday in a Pontiac, Mich. courtroom to between 10 and 15 years in prison.

Both Crumbleys were found guilty in separate trials on four counts of involuntary manslaughter. Each of those charges carried a maximum penalty of 15 years, and the sentences are to be served concurrently.
