"Key Moments in James Crumbley Manslaughter Trial: Witness Testimonies and Emotional Video Evidence"

The defense has rested in the manslaughter trial of James Crumbley, the father of the teenager who fatally shot four students at a Michigan high school in 2021. Prosecutors argued that James Crumbley acted with "gross negligence" by not properly securing the firearm and ignoring warning signs of his son's mental health, while the defense pleaded ignorance on his behalf. Closing arguments are expected later Wednesday, and James Crumbley faces up to 15 years in prison if convicted. The case tests the limits of who is responsible for a mass shooting, with prosecutors aiming to expand the scope of blame in mass shootings by holding the shooter's parents responsible for the deaths.
