School shooter Ethan Crumbley opened fire in a Michigan school, killing four student. He pled guilty to all charges and is now serving life in prison. His parent James and Jennifer Crumpley are also charged with involuntary manslaughter. Prosecutors say they should have been aware of their son's mental health and should not have made it possible for him to have access to weapons.  The parents' trials are expected to begin later this month, but now Jennifer Crumbley has asked a judge to dismiss three witnesses say their testimony could prejudice a jury.  
A judge has ruled however, that two of the witnesses will be allowed to testify, with a narrow focus.  The jury will also be allowed to see surveillance video from the school.
