A jury has found Jennifer Crumbley, whose son killed four students at a Michigan high school mass shooting in 2021, guilty of manslaughter a crime she was charged with because she and her husband gave her then 15-year-old son a gun despite his behavioral issues.

Crumbley, 45, was found guilty on all four counts of involuntary manslaughter prosecutors charged her with over her role in the deadly shooting at Oxford High School in Michigans Oxford Township. Its believed to be the first time the parents of a shooter have been held accountable for their childs actions.

Each charge carries a a maximum penalty of 15 years. Her sentencing is scheduled for April 9.

Prosecutors argued that she and husband James Crumbley whos set to stand trial next month were responsible for their 15-year-old son Ethans rampage because they bought him a semi-automatic handgun just days before he opened fire at school, even though their son was struggling with his mental state and exhibiting disturbing behavior.
