There was an article out yesterday stating the shooter’s sister was a transgender claiming to be male. She worked as a tour guide someplace near Missoula, MT. Apparently she was back in Dayton with his/her boyfriend and he shot them both. That may be the trigger point for the shooting.
That's not true, there is no evidence she was transgender.
When the Dayton shooter killed his sister, he cut short a life full of promise, friends say
