When I took a class on CCW and the law, one thing that was stressed is that in the eyes of law enforcement, flight=guilt. After a self-defense shooting, you MUST be the first to call 911 and report the incident.
This does not mean you are required to stay in a potentially-dangerous location. If you think the thug's friends will shortly show up, it is OK to leave the immediate area in order to get to a safer location (like the police station) in order to get in contact with the police.
They were coming from a wedding reception and buying a bottle of wine at the quick stop, then shot up a car and fled the scene, went to their hotel room where the TV news would be available to them, and then the next morning fled the jurisdiction.
From the article: “”He did not call the authorities; the police arrested him the following day, finding him because a witness noted his license plate number.””
There are some serious questions about this guy.
