Ward:  The father was a IRRESPONSIBLE Gun Owner, plain and simple.  Had the father had this weapon in a LOCKED gun safe, his son would be alive today.  For how long,  do NOT know as I believe the son had serious Mental Health Issues, and it was just a matter of time before he "BLEW"  up again.   The father should be PROSECUTED and not be allowed to ever own a weapon again.  His son was PROSECUTED by Death by Cop.............
