DAYTON, Ohio - A masked gunman in body armor opened fire early Sunday in a popular entertainment district in Dayton, Ohio, killing nine people, including his sister, and wounding dozens before he was quickly slain by police, officials said.
It was the second U.S. mass shooting in less than 24 hours, and no motive has been explained.
The gunman was white and six of the nine killed were black, police said.
Bellbrook Police Chief Doug Doherty said he and his officers werent aware of any history of violence by Betts, including during high school, and had no previous contact with him.
The Ohio shooting came hours after a young man opened fire in a crowded El Paso, Texas, shopping area, leaving 20 dead and more than two dozen injured.
