The parents of Ethan Crumbley are facing charges of involuntary manslaughter for allegedly allowing their son access to a gun. Crumbley is accused of killing four students during a school shooting in Michigan in November 2021. Prosecutors want his parents to stop acting all "lovey-dovey" in court after patriarch James Crumbley was seen mouthing "I love you" to his wife, Jennifer, at a court hearing last December following their dramatic arrest at a warehouse in Detroit where they were allegedly hiding out.
