"Gun Safe Default Code and Testimony Highlight James Crumbley Trial"

Detective testifies that James Crumbley stored two firearms in a gun case with the default combination "0-0-0," showing gross negligence in securing the weapons. Prosecutors aim to expand blame in mass shootings by holding parents responsible for providing firearms and disregarding signs of mental health issues. Crumbley faces involuntary manslaughter charges and up to 15 years in prison if convicted, while his son, Ethan, is serving a life sentence for the shooting. The trial raises questions about parental responsibility in mass shootings and the lack of proper firearm security.
