Adelia Johnson thought she understood where Connor Betts was coming from when he shared that he'd contemplated suicide, and even when he once told her in a drunken call about wanting to hurt people.
As they dated this spring, they bonded over their struggles with mental illness, she said, so his dark thoughts didn't seem so abnormal.
Now investigators are trying to figure out why Betts, 24, gunned down nine people, including his own sister, and wounded many more Sunday outside a strip of bars in Dayton, Ohio, before
police shot him dead.
