Anyone know why the Dayton, Ohio shooter shot his sister?

Or, why he chose that particular club to shoot all of those people? I heard he was an Antifa follower, have they discovered any more information on his motives?

I can’t deal with all of these mass shootings. Someone yesterday said to me she isn’t afraid to travel abroad anymore, because it’s just as bad here in the US. I’ve been telling people that for years now, but finally the national news is reporting the total number more. Think about it. If there are over 200 mass shooting this year, are you aware of 200 because you heard reports of 200 at the time they happened? You probably only know about 10 off the top of your head.
