Jennifer and James Crumbley, the first parents of a mass school shooter in the U.S. to be convicted of involuntary manslaughter for the shooting, are set to be sentenced on Tuesday.

Prosecutors asked that each parent be given 10 to 15 years in prison after separate juries found them each guilty of four counts of involuntary manslaughter earlier this year. Their son, Ethan, is serving a life sentence for the murders of four of his classmates at Oxford High School in Oxford, Michigan, on Nov. 30, 2021, when he was 15 years old.
