Oxford High School shooter's parents to face manslaughter trial.

The parents of Ethan Crumbley, a teenager who killed four students at a Michigan high school, will stand trial for involuntary manslaughter, according to a state appeals court ruling. The court said the murders would not have happened if the parents hadn’t purchased a gun for their son or taken him home from school on the day of the shooting. Ethan Crumbley has pleaded guilty to terrorism and murder and could be sentenced to life in prison without parole. The parents' lawyers declined to comment, citing a gag order.
