The latest: Unclear if Ohio shooter targeted sister

DAYTON, Ohio (AP) The gunman who attacked the nightclub district in Dayton, Ohio, this weekend mowed down so many people so quickly that authorities say he probably wasn’t targeting anyone.

Beyond that, investigators deemed it too soon to say what touched off Connor Betts’ 30-second rampage that left nine people dead early Sunday.

Among the questions: Why would the 24-year-old have shot his 22-year-old sister Megan, the youngest victim? And what could authorities have done to prevent the attack that ended when officers gunned him down?

Some students who went to high school with Betts in a Dayton suburb note that he got suspended for making threats. School officials haven’t discussed those details.

Others considered Betts a nice guy. One friend even described him as “the kind of kid you’d want as a son.”

Police Chief Richard Biehl says it’s hard to believe that the gunman in the Dayton attack didn’t recognize his sister when he opened fired and killed her and eight other people.

Police say 24-year-old Connor Betts opened fire around 1 a.m. Sunday in a popular entertainment district. Police say he was fatally shot by officers within 30 seconds.

Biehl told reporters Monday that it is hard to believe Betts would have targeted his own sister but also difficult to imagine he wouldn’t have recognized her.

Betts was white and six of the nine killed were black, but police have said the quickness of the rampage made any discrimination seem unlikely. Biehl reiterated Monday that there is no indication that race was a motive in the attack, but the investigation is continuing.
