Dayton gunman Connor Betts allegedly had an obsession with killing and death as former high school classmates say the warning signs were there long before he slaughtered his sister and eight others.
The 24-year-old massacred nine people, including his 22-year-old sister Megan Betts, with an assault rifle at about 1am on Sunday in a section of the city known for its nightlife.
Betts, who was wearing body armor and a mask during the rampage, was shot dead by police outside a bar about 30 seconds after he first opened fire.
As investigators try to piece together a motive and determine if he targeted his sister, a disturbing profile has since emerged painted by former classmates who claim he was obsessed with death, had a history of violence and threatened to shoot up the school.
Multiple former classmates at Bellbrook High School have said they reported Betts' behavior to police but claim nothing was done to address the red flags and say they weren't surprised he was responsible for the recent massacre.
Jessica Masseth, a female classmate who was named on a rape list compiled by Betts, said she contacted police at the time and that she handed her phone over to authorities so they could see threats he sent her.
