Authorities say Connor Betts was killed by police less than a minute after he started shooting a .223-caliber rifle into the streets of a popular Dayton nightlife area around 1 a.m. Sunday.

They say his 22-year-old sister, Megan, was the youngest of the deceased victims, who were all killed in the same area.

The victims include four women and five men. They are:

  • Megan Betts,22
  • Nicholas Cummer, 25

  • Beatrice Warren Curtis, 26
  • Lois Oglesby, 27
  • Sayid Saleh, 28
  • Monica Brickhouse, 29
  • Logan Turner, 30
  • Derek Fudge, 57

Mayor Nan Whaley says Betts was wearing body armor and had additional high-capacity magazines.

Investigators haven’t publicly discussed a possible motive.

It was the second U.S. mass shooting in less than 24 hours.
