Gunman’s sister among 9 killed during second US mass shooting in 13 hours

Authorities have found writings linked to Dayton, Ohio, shooting suspect Connor Betts that show he had an interest in killing people, two federal law enforcement sources told CNN. A preliminary assessment of the writings, found during the execution of a search warrant, did not indicate any racial or political motive, the sources said. 

At an afternoon press conference, police said they are looking for any indication of motives.

“We’re always looking at what could have motivated such a horrific action as this, and like I said this morning, we’re interviewing dozens of people and going through a lot of different electronic evidence, other evidence to try to determine that. We don’t have that answer yet,” Lt. Col. Matt Carper, Dayton Deputy Chief of Police said. “But speculating at this point would be premature.”
