In 2021, Ethan Crumbley brought a gun to school and killed four students. His mother, Jennifer Crumbley, has been convicted of involuntary manslaughter in connection to the attack, marking the first time a parent has been held criminally responsible for a school shooting. Prosecutors argued that Jennifer was negligent in failing to inform the school about the family’s guns and for allowing her son access to the 9mm handgun used in the attack. Her husband, James, is set to face trial next. Meanwhile, Jennifer’s defense argued that she was not responsible for buying or storing the gun and that there were no warning signs that her son would commit such a crime. Ethan, who was 15 at the time of the shooting, has pleaded guilty to the attack and is currently serving a life sentence.
