"Oxford High School shooter's mother on trial: Testing responsibility for mass shooting"

The trial begins for Jennifer Crumbley, the mother of the teenage boy who killed four people during a shooting at Oxford High School. She and her husband are both facing four counts of involuntary manslaughter. Prosecutors aim to prove that Crumbley shares blame in the November 2021 shooting. The defense argues that she was not well-equipped to handle the situation and could not have foreseen the mass shooting based on what she knew. The trial includes opening statements, jury instructions, and the exclusion of certain evidence.
