Dayton, Ohio shooting: Gunman's sister among nine killed by Connor Betts

That is so horrible that another event like that has happened again ! This and the tragic event in Texas so close together. My sympathy to the families and friends of those who lost their lives here or were injured from these disturbed individuals.

Since he was traveling with her, how does he end up shooting his own sister? Did he suddenly not recognize her? Was this an accident? Did the accident lead to the rest? Was killing her part of the plan? Why don't people like that save us all time, damage and heartache by offing themselves instead of going after others?
