The father of the 14-year-old accused of killing four people at a Georgia high school faces 180 years for multiple charges, including involuntary manslaughter and second-degree murder. Prosecutors allege that Colin Gray bought his son an AR-15-style rifle despite being aware of his son’s mental health issues and past threats of violence. His son, charged as an adult, faces life without parole. Both return to court on December 4. Dave Aronberg joins Morning Joe to break down the latest.
