I'm afraid the homeowner will be losing his freedom soon. At least based on the information that was provided anyway. The 23-year old deceased man was in the vehicle, correct?
Did the shooter contact police?
Could the homeowner just shoot out the tires?
Was the homeowner in any immediate life threatening danger? Was his family?
I'm on the outside looking in, no doubt. I'm just left with so many questions and will wait until the investigation is complete to understand it all.
