It’s an unthinkable headline to wake up to, a husband and father calls 911 to report that he’s killed his entire family and when police arrive, all six people are dead, including the killer.  That’s what Kansas officials are dealing with this week after 53 year old Ronald Williams shot his four children, their mother and himself this week.  It comes on the heels of a Michigan father just last month killing his six kids and wife and setting his home on fire, and an Iowa father killing his six family members in June.  Criminologists have isolated many of the common traits these men share, including the fact they are often educated, successful and family oriented, but have suffered some recent financial or relationship difficulty.
