Charges could come Monday in a dispute over a parking space during a comedy concert starring Kevin Hart that led to a shooting on Saturday night. It happened in the parking lot of the Palace of Auburn Hills. The shooter is a Detroit police officer who was off duty at the time. Investigators say the officer was trying to change a flat tire when he got into an argument, then a scuffle that led to gun fire. The gunshot victims are a 32 year old male from Detroit and a 31 year old woman from Harper Woods. There were no life threatening injuries.
