DAYTON, Ohio (AP) — An ex-girlfriend of the Ohio gunman who killed nine people says he showed her a video of the Pittsburgh synagogue shooting on their first date. Adelia Johnson says in an emailed statement to The Associated Press that Connor Betts often joked about having dark thoughts. She says he told her that he had bipolar disorder and that his talk didn’t scare her because she thought it was a symptom of his mental illness.
