Connor Betts

During his senior year of high school, Connor Betts seemed to always have caffeine pills in one hand and an energy drink in another. He was unable to sleep, he told his then-girlfriend Lyndsi Doll, because of dark, animal-like shadows that tormented him at night.

The 24-year-old gunman who killed nine people in a rampage in Dayton, Ohio, had a troubled past, including threatening fellow students in high school, authorities said, but police said it was too soon to establish a motive for the slaughter.

In the hours before the mass shooting here, Connor and Megan Betts, brother and sister, drove the family's 2007 Corolla together to this city's historic Oregon District, an area alive on a summer night with restaurants, bars and nightlife.
