“It’s just a tragedy for no reason,” said Donna Johnson, who lost her nephew Thomas Nichols in the massacre Sunday morning.
But the motive might never be known. The killer, Connor Betts, was gunned down by police about 30 seconds after his first shot, Dayton Police Chief Richard Biehl said.
While his motive remains a mystery, a dark picture is emerging of the shooter.
Authorities searched the Betts’ family home in Bellbrook, a suburb southeast of Dayton, and uncovered writings that expressed an interest in killing people, two law enforcement sources told CNN.
But the writings did not indicate any racial or political motive, sources said.
Former schoolmates said they were on a “hit list” Betts created back in high school. One described Betts as “dark and depressive.”
The gunman had 100-round drum magazines
Surveillance video shows the chaos unfold as a shooter targets people enjoying a Saturday night out in Dayton’s Oregon District.
As gunshots ring out, people start to run, ducking into bars and clubs.
Large groups pour into open doorways, escaping the shots that riddle the street.
Within seconds, the shooter is brought to his knees by police just before he’s able to enter a nightclub.
Biehl said his officers patrolling the area heard the gunshots, saw people fleeing and immediately ran toward danger.
“The officers immediately advanced toward the gunfire and within approximately 20 seconds, they engaged the suspect, who was actively firing and attempting to enter a crowded liquor establishment,” the police chief said.
“The threat was neutralized at approximately 30 seconds of the suspect firing his first shot.”
But the devastation was already done. Betts managed to fire dozens of shots with a .223-caliber high-capacity rifle with 100-round drum magazines.
Nine states, plus the District of Columbia, ban large-capacity ammunition magazines. Ohio isn’t one of them.
The nine states are California, Colorado, Connecticut, Hawaii, Maryland, Massachusetts, New Jersey, New York and Vermont, according to the Giffords Law Center to Prevent Gun Violence.
Among the states that ban high-capacity magazines, some prohibit magazines that hold more than 10 rounds, and others ban magazines that hold more than 15 rounds.
Back in Ohio, Dayton Mayor Nan Whaley emphasized that just a few seconds of shooting led to nine deaths.
“I really want to think about that minute,” she said. “The shooter was able to kill nine people and injure 26 in less than a minute.”
The victims range from 22 to 57 years old
The city of Dayton identified the nine people killed in the shooting:
— Lois L. Oglesby, 27
— Megan K. Betts, 22, the shooter’s sister
— Saeed Saleh, 38
— Derrick R. Fudge, 57
— Logan M. Turner, 30
— Nicholas P. Cumer, 25
— Thomas J. McNichols, 25
— Beatrice N. Warren-Curtis, 36
— Monica E. Brickhouse, 39
Nine people remained hospitalized Sunday evening, hospital officials said.
The gunman’s sister is among the dead
Megan Betts, the sister of the suspect, was one of the nine people killed.
Police did not detail the Betts siblings’ relationship. But they did say that the two arrived together but separated at some point.
Biehl said the shooter killed his sister and wounded his male companion.
Authorities said they don’t think the male companion, who had driven to the scene with the shooter and his sister, had advance knowledge of the attack, two law enforcement sources told CNN.
“They are victims, and we’re treating that as such — them as victims,” he said.
