In Michigan, a jury found James Crumbley guilty of involuntary manslaughter for failing to prevent his teenage son from going on a shooting spree which killed four students at Oxford High School in 2021. James Crumbley’s wife, Jennifer Crumbley, was convicted on the same charges last month after prosecutors successfully argued the couple ignored obvious warning signs and bought the gun for their son. It’s the first time parents have been directly charged for deaths caused by their child in a mass shooting. They’ll both be sentenced next month.
