A Michigan judge ruled Friday that school shooter Ethan Crumbley can be sentenced to life in prison without parole for the murders of four students at Oxford High School in November 2021.

Seven others were wounded  in the shooting.

Crumbley, 15 at the time of the shooting, pleaded guilty a year ago to 24 counts, including first degree murder and terrorism, as CrimeOnline previously reported.

Juveniles convicted of first degree murder cannot be automatically sentenced to life without parole as adults are, prompting Friday’s hearing, called. Miller hearing, according to ABC News.

“The prosecution has rebutted the presumption, by clear and convincing evidence, that a sentence to life without parole is a disproportionate sentence,” Judge Kwamé L. Rowe said Friday.

Crumbley will be formally sentenced on December 8.

The hearing began in July with testimony from survivors of the shooting, which killed Hana St. Juliana, 14; Madisyn Baldwin, 17; Tate Myre, 16; and Justin Shilling, 17.

Crumbley’s parents, Jennifer and James Crumbley, are awaiting trial on involuntary manslaughter charges after they failed to recognize their son’s warning signs in the months leading up to the shooting. They have pleaded not guilty.
