2 mass shootings in less than 24 hours shock U.S.

Two mass shootings at crowded public places in Texas and Ohio in less than 24 hours claimed at least 29 lives and left scores injured, a shocking carnage even in a country accustomed to gun violence.

In the Texas border city of El Paso, a gunman opened fire Saturday morning in a shopping area packed with thousands of people during the busy back-to-school season, killing 20 and injuring more than two dozen, many of them critically. The shooting was being investigated as a possible hate crime as authorities worked to confirm whether a racist, anti-immigrant screed posted online shortly beforehand was written by the man arrested in the attack on the 680,000-resident border city.

Despite initial reports of possible multiple gunmen, the man in custody is believed to be the only shooter, police said.

Many of the victims were shot at a Walmart, according to police, who provided updates about the shooting in English and Spanish in the largely Latino city. The shopping area is about 5 miles (8 kilometers) from the main border checkpoint with Ciudad Juárez, Mexico.

Just hours later in Dayton, Ohio, a gunman wearing body armor and carrying extra magazines opened fire in a popular nightlife area, killing nine and injuring at least 26 people.

The Saturday shooting in El Paso and the Sunday shooting in Dayton were the 21st and 22nd mass killings 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.

Including the two latest attacks, 125 people had been killed in the 2019 shootings.

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 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 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.
