Less than 24 hours after a mass shooting in El Paso, Texas, left 22 people dead, another shooter in Dayton, Ohio, killed nine people, including his sister.

Connor Betts, 24, killed his sister Megan Betts, 22, and eight others before he was shot and killed by police. 27 others were wounded. Police have not commented on a motive for the attack. The other victims were Monica Brickhouse, Nicholas Cumer, Derrick Fudge, Lois Oglesby, Logan Turner, Beatrice Warren-Curtis, Thomas McNichols and Saeed Saleh.

On Friday, the Montgomery County coroner’s office said all the victims except for one received multiple gunshot wounds.

A classmate, Addison Brickler, described Megan Betts saying she always had a smile on her face, according to the AP. Brickler said she doesn’t understand why Betts’ brother did this.
