New details emerge in Oxford High shooting timeline after Appeals Court ruling.

The Michigan Court of Appeals has ruled that there is enough evidence for the parents of the Oxford High School shooter to stand trial on involuntary manslaughter charges. The ruling revealed a new timeline of events leading up to the shooting, including text exchanges between Jennifer Crumbley and her son just 10 minutes before he started shooting. The timeline also revealed that both parents were aware of their son's mental health issues and that James Crumbley purchased the gun used in the shooting just four days before the incident.
