LANSING, Mich. (Michigan News Source) – The teenager who pleaded guilty to murdering four classmates and injuring six others at Oxford High School in Nov. 2021 will not be allowed to appeal his life without parole sentence.

The Court of Appeals denied the shooter’s request and the attorney arguments.

The shooter’s attorneys argued the shooter suffered from “cognitive-adaptive dysfunctions” from fetal alcohol spectrum disorder. In addition, they said defense attorneys made errors during the trial and that the life without parole sentencing was unconstitutional.

While the shooter spends his life behind bars, his parents are serving 10-15 years for involuntary manslaughter related to the shootings. James and Jennifer Crumbley are both appealing the convictions. A jury found both ignored their son’s mental illness and cries for help prior to the shooting.

Fourteen-year-old Hana St. Juliana, 16-year-old Tate Myre, and 17-year-olds Madisyn Baldwin and Justin Shilling died in the shooting.
