9 killed in Ohio in second US mass shooting within 24 hours August 4, 2019Witnesses comfort one another at the scene of a mass shooting, Aug. 4, 2019, in Dayton, Ohio. (AP/John Minchillo)(AP/John Minchillo)9 killed in Ohio in second US mass shooting within 24 hoursIn the second shooting in the U.S. within 24 hours, nine were killed and dozens were wounded in Dayton, Ohio.By Dan Sewell and John Minchillo, Associated PressA gunman wearing body armor and carrying extra magazines opened fire in a popular nightlife area of Dayton, Ohio, killing nine and injuring dozens, authorities say, in the second U.S. mass shooting in less than 24 hours.Dayton police patrolling the area responded in less than a minute to the shooting, which unfolded around 1 a.m. Sunday on the streets of the Oregon District, Dayton Mayor Nan Whaley said at a press conference.Whaley said if the police had not responded so quickly, “hundreds of people in the Oregon District could be dead today.”The Oregon District is a historic neighborhood that Lt. Col. Matt Carper described as “a safe part of downtown,” home to entertainment options, including bars, restaurants and theaters.The gunman, who has not been identified by authorities, was shot to death by responding officers. Whaley said he was carrying a .223-caliber rifle and had additional high-capacity magazines with him. Police believe there was only one shooter, and they have not yet identified the suspect or a motive.At least 26 others are being treated at area hospitals, though no details about their conditions have been released.Miami Valley Hospital spokeswoman Terrea Little said the hospital had received 16 victims, but she couldn’t confirm their conditions. Kettering Health Network spokeswoman Elizabeth Long said multiple victims from a shooting have been brought to system hospitals, but she didn’t have details on how many.Nikita Papillon, 23, was across the street at Newcom’s Tavern when the shooting started. She said she saw a girl she had talked to earlier lying outside Ned Peppers Bar.“She had told me she liked my outfit and thought I was cute, and I told her I liked her outfit and I thought she was cute,” Papillon said. She herself had been to Ned Peppers the night before, describing it as the kind of place “where you don’t have to worry about someone shooting up the place.”“People my age, we don’t think something like this is going to happen,” she said. “And when it happens, words can’t describe it.”‘There was a lot of rounds’Tianycia Leonard, 28, was in the back, smoking, at Newcom’s. She heard “loud thumps” that she initially thought was people pounding on a dumpster.“It was so noisy, but then you could tell it was gunshots and there was a lot of rounds,” Leonard said.Gov. Mike DeWine issued his own statement before 7 a.m., announcing that he’s ordered flags in Ohio remain at half-mast and offered assistance to Whaley.“Fran and I are absolutely heartbroken over the horrible attack that occurred this morning in Dayton, the statement said. “We join those across Ohio and this country in offering our prayers to victims and their families.”The FBI is assisting with the investigation. A family assistance center was set up at the Dayton Convention Center.The Ohio shooting came hours after a 21-year-old male opened fire in a crowded El Paso, Texas, shopping area, leaving 20 dead and more than two dozen injured. Just days before, on July 28, a 19-year-old shot and killed three people, including two children, at Northern California’s Gilroy Garlic Festival.Sunday’s shooting in Dayton is the 22nd mass killing of 2019 in the U.S., according to the AP/USA Today/Northeastern University mass murder database that tracks homicides where four or more people killed — not including the offender. The 20 mass killings in the U.S. in 2019 that preceded this weekend claimed 96 lives.
