Michigan judge weighs sentence for teenage school shooter after hearing chilling accounts of violence

Teenager Ethan Crumbley pleaded guilty to killing 4 students and wounding 7 in a 2021 Michigan high school shooting.
Crumbley expressed violent intentions in journal entries, recordings, and online searches before the attack.
A hearing will determine if Crumbley receives life without parole or a shorter sentence with the possibility of parole.
Prosecutors highlighted Crumbley's premeditation while the defense argued he can still be rehabilitated.
Testimony from victims detailed the shooting's trauma; Crumbley's parents still face charges over missing chances to prevent it.
