A U.S. teenager has been sentenced to life in prison without the possibility of parole for the 2021 Oxford High School shooting in Michigan. Ethan Crumbley, 17, killed four students and injured seven others. The sentencing follows a trial where he was found guilty of terrorism and four counts of first-degree murder. Prosecutors presented evidence of Crumbley’s planning and obsession with violence prior to the attack. The judge emphasized the severity of the crimes and the devastating impact on the community. Crumbley’s defense argued for leniency due to his age and mental health, but the court ultimately deemed the crimes too egregious for anything less than a life sentence. This case has reignited debates about school safety, gun control, and juvenile accountability.
